    Dear Friends,

      Welcome to the 20th Anniversary issue of Sulfuric

     Acid Today magazine. Where does the time go? It seemslike just yesterday we began compiling the first issue of

    Sulfuric Acid Today. I would like to thank all of those com-

    panies and individuals who were with us from the beginning

    and believed in the vision of producing a sulfuric acid industry

    magazine that would focus on the latest products and technol-

    ogy to improve the maintenance and operations of acid plants.

    What began in 1994 as a black and white newsprint tabloid

    of just 16 pages has grown into a full-color glossy magazine

    that today reaches sulfuric acid professionals globally. I’m

    extremely proud and grateful to be part of an industry that

    is willing and open to the exchange of information. I’m

    looking forward to another two decades of publishing

    Sulfuric Acid Today magazine as well as sponsoring

    sulfuric acid roundtables and workshops in the U.S.

    and Australia. I hope you find this issue both helpful

    and informative.

      In this issue, you will find several articles that

    take a look back over the last 20 years. Be sure to

    read such articles as “Sulfuric acid industry evolvesover 20 years” (page 6), “Sulfuric Acid Today  revis-

    its 20 years of cover stories” (page 11), “Twenty years

    of safety” (page 21), “Global sulfuric acid market–a

    twenty year retrospective” (page 22), “The Roberts

    Company highlights accomplishments” (page 34), and

    “NORAM—The best of the past 20 years” (page 40).

    I would like to thank our new and returning Sulfuric

     Acid Today advertisers, including Acid Piping TechnologyInc., Beltran Technologies, Central Maintenance & Welding,

    Chemetics Inc., Corrosion Services, El Dorado Metals Inc.,

    FLEXIM, Haldor Topsøe A/S, Kimre, Koch Knight LLC,

    and Weir Minerals Lewis Pumps.

      As this issue goes to press, we are finalizing the last

    details of the 2014 Australasia Sulfruic Acid Workshop,

    which will take place March 24-27, 2014, in Adelaide, South

    Australia. We will be hearing some excellent presentations

    from our Co-Sponsors as well as delving into some perti-

    nent plant discussion topics. I’m looking forward to another

    successful meeting.

      We are currently compiling information for our Fall/Win-

    ter 2014 issue. If you have any suggestions for articles or other

    TORONTO, Ontario—Chemtrade

    Logistics Income Fund announced today

    that it has completed its previously-

    announced acquisition of Parsippany,

    NJ-based General Chemical HoldingCompany (General Chemical). The final

    total cash purchase price is expected to

    be approximately $900 million, after a

    working capital adjustment and payment

    of post-closing taxes.

      “This is a historic event for

    Chemtrade. The acquisition of General

    Chemical adds significant size, scale and

    scope to Chemtrade’s existing product

    and service platform,” said Chemtrade

    President and Chief Executive Officer,Mark Davis. “General Chemical has

    strong portfolio alignment with our

    current business, enhancing our existing

    sulfuric acid geographic footprint and

    greatly expanding our water treatment

    business so it now extends across most

    of North America. The acquisition of

      The sulfuric acid industry is mourning the

    loss of Louis John Doerr, Jr., who passed away

    at age 90 on December 28, 2013. A native of

    Saint Louis, Mo., Lou began his education at

    Washington University before active duty in

    World War II came calling. Lou left school at the

    start of the war to join the Navy. He flew rescue

    missions in the Pacific, picking up

    downed U.S. airmen at sea. After

    the war ended, Lou returned to

    his home in Saint Louis and his

    studies at Washington University,

    graduating with a degree in

    Mechanical Engineering.

      Lou spent time as a salesman

    for Aero Tool before finding hisway to Chas. S. Lewis & Co. in

    1969. Lou and three other investors

    purchased the company from Jim Lewis, son

    of the company’s founder, Charles Lewis.

    As Chairman of the Board, Lou focused on

    changing the company from a local success to

    an international sensation. At the start of Lou’s

    tenure, Lewis®  Pumps products were sold in

    the United States and Canada. Thanks to Lou’s

    persistence and his many contacts throughout

    the industry, within eight years Lewis® Pumpsproducts were sold in more than 90 countries

    around the world. Building on that success, Weir

    Minerals Lewis Pumps today has products in

    use in more than 120 countries. Though Lou and

    his investor partners sold the company in 1977,

    Lou stayed on as the Vice President of Sales until

    his retirement in 1995.

      As much as Lou was instrumental in

    making Lewis®  Pumps a well-respected name

    and sought-after brand throughout the world,

    his reach was felt far beyond the walls of the

    company. Lou was an avid supporter of the

    British Sulfur Conference and was a

    member of the British Sulfur Board

    of Directors. He also teamed with

    others in the industry to establish

    the Sulfuric Acid Roundtable as a

    way for participants to exchange

    ideas and spur industry growth.

    Lou was considered an expert inthe industry and his contributions

    will indeed be missed.

      In his personal life, Lou and his wife

    Rosemary had recently celebrated their 63rd

    wedding anniversary. Their five children,

    numerous grandchildren, and one great-

    grandchild helped complete the Doerr family–

    Lou’s lasting legacy. Always active in the

    community, Lou was an avid fan of local sports

    teams as well as a skilled golfer and tennis player.

    He actively supported St. Louis FIRST Robotics,an organization aimed at inspiring high school

    students to be technology leaders with future

    careers in engineering and science. Lou’s

    presence within his family, his community, and

    the sulfuric acid industry will be greatly missed.

      The Lewis Pumps family and the sulfuric

    acid industry have been deeply saddened by

    the sudden passing of Robert “Bob” Borges

    on January 5, 2014 at the age of 62. Bob’s

    genuine nature and kind heart will be missed

    by his friends throughout the industry as well

    as by his beloved wife, Kathy, and their two

    daughters, Liz and Margie.

      Raised in Milwaukee, Wis.,

    Bob graduated as a metallurgist

    from Michigan Technical Institute.

    He began his career with the

    Falk Corporation in Milwaukee,

    working on some of the largest gear

    reduction systems in the world.

    Bob later worked for American

    Magotteaux in Nashville, Tenn.,

    handling technical sales and

    engineering troubleshooting.

    In March of 1985, Bob made the move to

    Chas. S. Lewis & Co., Inc. in Saint Louis, Mo.

    Hired as a metallurgist, Bob was instrumental

    in developing new materials for use in acid

    pumps. Over the years, he moved through

    the organization as the Vice President of

    Engineering and later the Vice President ofSales & Marketing. His vast knowledge made

    him a natural fit for field work, and Bob was

    often called on by customers around the world

    to diagnose pump problems. He revamped the

    way Lewis®  Pumps products were built and

    tested, increasing the profitability of pumps

    while also raising pump quality for customers.

    Bob also helped move the company in new

    directions, such as initiating the company’s first

    molten salt pump and opening the door to the

    company’s first sulfur recovery units.

      Bob was highly respected both at Lewis

    Pumps and throughout the industry. Coworkers

    remember Bob as a good friend

    who would always stand behind

    his workers and stand up for

    what was right. He was loyal and

    supportive with an ever-present

    eye on moving the company and

    the whole industry forward. Bob

    enjoyed the opportunity to share

    his expertise with others, and

    throughout the years, he helped

    many companies solve complex

    problems and improve their systems.

      Retiring from Weir Minerals Lewis

    Pumps in 2009, Bob continued to work in the

    industry as a consultant. Outside of work, Bob

    was a good golfer, always striving for his first

    hole-in-one, and he had significant interest

    in financial investments. He was very proud

    of his family, and often spoke of his wife anddaughters. Bob’s boisterous laugh and beaming

    smile always announced his arrival and will

    be fondly remembered by those who knew

    him. Bob was indeed one-of-a-kind and his

    untimely passing has left a void that will not

    soon be filled.

    BRUSSELS—Chemical producer Solvay

    SA has hired Credit Suisse Group to

    find a buyer for its sulfuric acid unit and

    approached private equity firms about

    a deal that could reach $800 million,

    according to people familiar with the

    matter.  The unit, referred to as eco services,

    has annual earnings of around $110

    million before interest, tax, depreciation

    and amortization.

      Solvay said it would explore strategic

    options for the unit but did not give more

    details. A Solvay spokeswoman did not

    respond to a request for comment on

    the details of the sale. A Credit Suisse

    spokesman declined to comment.

      Solvay’s eco service businessproduces and regenerates sulfuric acid,

    which is used as a catalyst at refineries in

    the production of high-octane gasoline.

      The unit is a supplier to the largest

    refineries on the U.S. West Coast, along

    the U.S. Gulf of Mexico and in the U.S.

    Midwest and Canada. It accounted for

    9 percent of Solvay’s net sales of $4.32

    billion in 2013.

      Solvay Chief Executive Jean-Pierre

    Clamadieu said a sale of eco serviceswould simplify Solvay and allow it to

    reallocate resources to fast-growing

    businesses.

      “I think this business could be

    qualified as a cash cow or a sustainable

    cash generator to use a nice terminology,”

    Clamadieu said about eco services.

    VANCOUVER, British Columbia—

    Kansanshi Mine says it will save about

    $150 million annually once the new copper

    smelter is in operation and producing

    sulfuric acid as a by-product. Kansanshi

    Mine, which is owned by First Quantum

    Minerals Limited, says the sulfuric acid

    is intended to be used in the solvent

    extraction/electrowinning (SXEW)

    process, thereby eliminating the need to

    purchase sulfur.

    Meanwhile, construction of the new

    1.2 million tonnes-per-annum copper

    smelter was approaching peak levels with

    commissioning intended to start in the

    second quarter of 2014, with the ramp-

    up continuing this year. The smelter is

    expected to operate at 80 percent of its

    design capacity by mid-2015 and achieve

    full capacity in the first quarter of 2016.

    TORONTO, ONTARIO—As part of its

    long term strategy to bring the Tsumeb

    smelter to internationally accepted

    environmental standards and consistent

    with directives issued by the Namibian

    Government, Dundee Precious Metals Inc.

    entered into a lump sum turnkey contract

    with Outotec for the engineering, supply,

    construction and commissioning of a

    facility to treat smelter off-gas and produce

    sulfuric acid. The project is progressing

    well with engineering 60 percent complete,

    all long lead items purchased and the

    earthworks component of construction

    complete. At this stage, the total capital

    cost to complete the acid plant currently

    under construction, including owner’scosts, is estimated at $240 million, up from

    the initial estimate of $204 million.

      The project remains on track for

    commercial operations and acid deliveries

    to commence in the fourth quarter of 2014.

      “The installation of the acid plant

    is expected to complete our major

    environmental upgrades at the smelter

    and our obligations to the government,

    thereby minimizing the environmental and

    political risks to the smelter,” said RickHowes, president and CEO.

  • 8/17/2019 Sulfuric Acid Today Spring/Summer 2014

    6/56

      The past 20 years have been a time

    of great change, both in the sulfuric

    acid industry and the world. Through it

    all, Sulfuric Acid Today  has been there,

    helping readers navigate an increasingly

    evolving global marketplace. To celebrate

    the 20th anniversary of the magazine, we

    asked several clients who have been with us

    from the beginning for their thoughts about

    the last two decades, and what they hopeis on the horizon. From new technology

    to environmental stewardship, safety

    enhancements to information sharing, it’s

    been an impressive two decades in sulfuric

    acid production. Here are just a few ways

    our advertisers have seen the changes fi rst

    hand.

    Cmps

    mc  For many years, the old adage “if itain’t broke, don’t fix it” applied in acid

    plants. Time and money were not spent on

    comprehensive, preventative maintenance

    programs. When something failed (often

    catastrophically), it was fixed quickly, so

    that production could resume as soon as

    possible. Otherwise, maintenance was

    done during scheduled turnarounds, and

    not given much consideration in between.

    But technological advances have changed

    all that.“Twenty years ago, many customers

    struggled to operate on a continuous

    twelve-month run between catalyst

    screenings,” Jack Harris, president of

    VIP International, said. “Today, with

    improved, shape-optimized catalyst, many

    customers run 30 to 36 months between

    catalyst screenings. The extended runtime

    has promoted maintenance planners to

    consider more comprehensive preventive

    maintenance programs. As converterruntimes are extended, other equipment

    must be examined to assure reliability

    throughout the campaign. Sophisticated

    and knowledgeable inspections must be

    maintained. In the early 1990s, we would

    respond to as many as a half a dozen

    catastrophic failures in towers per year.

    Today, through comprehensive inspections

    and preventive maintenance practices,

    these catastrophic failures are typically

    avoided.”

      Ed Knoll, president of Acid Piping

    Technology, added, “with more emphasis

    on safety and preventative maintenance,

    plants no longer run piping to the point of

    failure.”

      These longer cycles and focus on

    preventative maintenance mean that

    there are more pieces to juggle at each

    turnaround, as well. Plant management

    wants to get the most out of each facility,optimizing both efficiency and time during

    an outage. “Clients require a much more

    sophisticated work breakdown schedule

    for the turnaround as the focus on asset

    utilization is much greater,” Doug Royster

    of Central Maintenance and Welding,

    Florida, said.

    C sps  One of the most significant changes

    noted in our interviews was the businessrelationship between the sulfuric acid

    producer and the service contractor.

    Contractors weren’t always viewed as

    part of the “team,” but as a necessary evil

    required to perform the tasks the producer

    was unwilling or unable to complete with

    plant personnel.

    “Twenty years ago, the contractor

    was viewed as an outside entity and, many

    times, as an expendable labor force,” said

    Harris. “As one old, crusty maintenancemanager told me, ‘Son, you have to realize

    you have two strikes against you when you

    come through the gate as a contractor. If

    you were worth your salt, you would be

    working for a plant like we are.’ ”

    Luckily, attitudes are changing,

    providing a more productive, collaborative

    and safer workplace for everyone involved.

    “In the past, the contractor was generally

    evaluated on the end result and was left

    to his own devices as far as procedure,”

    said Harris. “Today, turning a blind eye to

    contractor protocol has been replaced with

    collaboration in examining every aspect

    of the work to assure mutual safety and

    productivity. Drawing upon the strength

    and expertise from each side in an effort

    of cooperation and respect has transformed

    an adversarial role into one of mutual

    success.”

      Another relationship that has changed

    over the years is that between plants,

    suppliers and contractors when it comes

    to information sharing. Gone are the days

    of secrecy, thanks to global conferences

    and workshops where problems and best

    practices are shared, often leading to

    unexpected solutions.  “Consolidation of companies has led

    to increased cooperation and collaboration

    between plants and suppliers. The industry

    has improved itself through the sharing

    of experiences,” said Bob Braun, director

    of engineering at Weir Minerals Lewis

    Pumps. “Conferences and seminars around

    the world have facilitated significant and

    valuable information transfer. This was

    unheard of prior to 1990. As companies

    and individuals throughout the industry

    share their ideas, experiences, triumphs

    and setbacks, the entire industry benefits

    and grows.”

      “Conferences allow a free exchange of

    information, ideas and best practices to be

    shared globally throughout the industry,”

    Harris said. “This magazine, Sulfuric Acid

    Today, has without a doubt had the largest

    effect on the network of information.”

    Chris Bailey, president of Roberts, a

    frequent attendee at industry conferences,

    shared these sentiments. “Our industry is oneof continuous learning and improvement,”

    Bailey said. “My hope would be that there

    continues to be communication of best

    practices among sulfuric plant operators

    because it is through continuous learning,

    and sharing of best practices, that safer and

    more efficient protocols can be developed.”

    fcs m

    swsp  Another major change over the pasttwo decades has been a trend toward

    environmental awareness and green

    practices. While spurred by stricter

    government regulations, many of these

    initiatives, including energy recovery and

    cogeneration projects, have in turn become

    money savers for facilities, while also

    helping to safeguard the environment.

    “With more stringent government

    regulations, plant designs are far more

    efficient. Single absorption plants are

    almost a thing of the past, being replaced

    by low emission facilities that were thought

    to be unachievable only a few decades ago,”

    Harris said. “Some plants have further

    enhanced environmental preservation by

    converting waste heat into cogeneration

    power plants, thereby reducing the need for

    fossil fuel.”

      “Energy efficiency has gone up to 95

    percent on most plants with heat recovery

    systems,” said John Horne, sales director,MECS, Inc. “There were about 10 reference

    HRS plants in the mid 1990s, compared to

    85 plus now.”

      Stricter environmental regulations

    have also led to innovative technological

    advances that might not have otherwise

    been developed. “The demand for lower

    emissions has allowed our R&D to develop

    and bring new catalysts and technologies

    to market that would not have had much

    demand unless plants were being forced toreduce emissions,” Frands E. Jensen, sales

    manager, environmental for Haldor Topsøe

    A/S, said. “And lower SO2  emissions

    requirements will most likely continue.”

    There are currently no overall international

    environmental regulations in place. Each

    country has its own regulations, and in

    some countries specific requirements are

    established for each individual plant. The

    European Union is, however, in a process

    aimed at establishing binding commonrules for the whole of the European Union

    valid for a number of important industrial

    sectors.

      Steve Puricelli of the MECS

    Technology Group also credits new

    technologies with helping reduce emissions.

    “SO2  emissions have been squeezed down

    to 1-2 pounds per ton, with scrubbers

    (DynaWave®) and regenerative scrubbers

    (SolvR™) getting the number down to 20

    ppm. And acid mist emissions have been

    reduced from 0.15 pounds per ton to 0.075

    pounds per ton.”

      The industry must continue to change

    and adapt, in order to take advantage of

    new technology and meet new challenges

    head-on. “As fossil fuels become more

    expensive, sulfuric acid production will

    become a coveted source of energy. For

    this reason many new plants will beconstructed with ‘built-in’ energy recovery

    features,” said John V. Orlando, P. Eng.,

    senior project manager/sales for NORAM

    Engineering and Constructors Ltd. But

    suppliers must be ready to adapt quickly

    to changing needs and environmental

    standards. “Technology providers will be

    called upon to provide acid plants that are

    proven and reliable to operate. To achieve

    these goals, more innovative designs

    and modern technologies will need to be

    developed and implemented.”These changes won’t stop any time

    soon, either. “We expect the continuation

    of lower emission levels for all types of

    plants and the need to expand existing plant

    capacity through improved plant, process

    and catalyst design,” said Mike Fenton,

    Chemetics Senior BD Manager for Acid

    Proprietary Equipment. “There will also

    be a need for continued improvement in

    heat recovery in sulfur burning acid plants,

    and greater recognition that the overalllifecycle costs of a plant and its equipment

    are of prime importance.”

      When all of this is taken together,

    from stricter emissions standards to power

    cogeneration to constantly improving

    technology, the end result is a win-win

    for the sulfuric acid industry and the

    environment. “The improved energy

    efficiency has resulted in additional

    power cogeneration allowing sulfuric acid

    producers to reduce energy costs, whilecontinuing to be good stewards of the

    environment,” said Bailey.

    ecms sc  The past two decades have brought

    about many changes affecting plant size,

    as well. From consolidation within the

    industry to cost concerns, the result is that

    facilities are getting bigger. “The last 20

    years have seen a significant increase in

    the physical size of the plants. A typicalplant used to produce 2,500 to 3,000 tons

    per day, whereas today the new plants

    are producing 4,500 tons per day,” said

    Doug Royster of Central Maintenance and

    Welding, Florida.

      MECS’ Horne echoed this sentiment.

    “In the 1990s, 3,500 STPD was considered

    a world class plant. Today, world class is

    closer to 5,500 STPD.”

      “The economy of scale trending

    toward larger plants for phosphate fertilizer

    production and quicker turnaround times

    have changed the landscape of the sulfuric

    acid market within the past decade,” said

    Mike Graeff, president of Koch Knight

    LLC.

    Dr. Hannes Storch, vice president,

    sulfuric acid/off-gas of Outotec, agrees.

    “Economy of scale has resulted in larger

    and larger plant sizes to keep the productioncosts down.” And Storch predicts that

    further economic pressure will result in

    even larger units.

      As with any other major change, larger

    plant size affects suppliers, too, demanding

    different solutions and new equipment.

    “Increased plant capacity has led to the

    development of larger pumps,” said Janey

    Marie Hartzell, marketing specialist, Weir

    Minerals Lewis Pumps. “This has spawned

    research and development efforts into new

    designs as well as the investigation of newmaterials. As the industry changes, so must

    any supplier hoping to stay at the top.”

    nw pcs

    cs  Along with larger plants and more

    complete maintenance schedules comes a

    need for new products and technologies.

    Many of our client companies have kept

    pace with the changes in the industry,meeting the demands and exceeding the

    expectations of facilities worldwide. Here,

    in their own words, are some of their

    most important advances over the last two

    decades.

    viP i  VIP International has long served

    the sulfuric acid industry by solving

    turnaround maintenance problems. In

    the last 20 years the VIP employees haveperformed almost 4,000 tower inspections.

    During that same time they have handled

    over 160,000,000 liters of sulfuric acid

    catalyst. With this much experience under

    their belts, they may not have seen it all, but

    when it comes to acid plants they’ve seen

    more than anyone else.

    Combining experience and innovation,

    VIP has focused on reducing downtime

    while providing superior service, safety,

    experience and productivity. The company

    continues to provide new and creative

    maintenance solutions for everything

    from converter maintenance to tower

    inspections and repair; mist eliminator

    removal, cleaning and installation to

    exchanger tube cleaning and sleeving;

    and catalyst handling and NOx removal

    to acid and sulfate neutralization. VIP is

    also relied on for SO2 and SO

    3  scrubbing,

    packing removal, tower demolition,

    distribution repair and replacement and

    high temperature entry.

    MeCS ic.  The MECS® HRS™ system has made

    practical the recovery of the last 25 percent

    of the energy generated by the sulfuric

    acid process as medium pressure steam.The more than 80 units in operation are a

    testament to the ease of use and robustness

    of this technology.

    The MECS® SolvR™ technology has

    opened doors to waste-sulfur recovery.

    Many flue gas streams contain sulfur,

    but are too dilute to recover as a usable

    product. SolvR™ technology now provides

    a way to recover the SO2 and process it in

    a conventional sulfuric acid plant. When

    SolvR™ technology is used instead of

    alkali based scrubbers, waste is convertedinto a useful product.

      There have been three significant

    improvements made to MECS®  Catalyst

    over the years. The shapes have been

    optimized to reduce pressure drop and to

    accommodate a greater build-up of dust.

    The activity has improved, allowing for

    better conversion, greater acid production

    or lower catalyst loadings. And thirdly,

    new formulations have allowed for lower

    operating temperatures, which translate to

    higher conversion or the ability to process

    higher concentrations of SO2.

    Mist eliminator technology has also

    been improved. The MECS® Brink® XP™element and Brink® AutoDrain™ features

    are the first major steps forward in new

    mist eliminator design. These elements are

    more efficient, operate at lower pressure

    drop and significantly reduce maintenance

    and operating issues by eliminating seal

    cups and drain legs.

      MECS® ZeCor® Alloys have opened

    the door to innovative distributor designs

    like the UniFlo®  Acid Distributor that

    improves the performance of sulfuricacid towers and at the same time reduces

    maintenance. ZeCor® has also made tower

    replacements a much more manageable task

    during a routine shutdown and provides the

    potential for easier maintenance repairs

    over the life of the tower.

      MECS® Operator Training Simulators

    (OTS) for sulfuric acid plants have

    brought operator training into the 21st

    century. MECS has created a suite of

    training simulators that are considered

    the ‘best-in-class’ method to prepareoperators for real world situations such

    as emergency scenarios, troubleshooting

    and process optimization. The benefits of

    the OTS include greater student interest

    and participation, as well as a significant

    increase in long-term knowledge retention.

    All of these equate to a greater return on

    the customer’s investment in t raining time.

    h tpsø  On the catalyst side, Haldor Topsøehas developed and introduced several new

    types of catalysts to meet the needs of

    facilities around the world.

    VK69™, the first cesium catalyst

    type tailored for lean gases, has with its

    unsurpassed performance helped numerous

    clients achieve lower emissions and higher

    production.

    The VK-WSX™ catalyst was

    developed as a low-temperature catalyst

    for the last bed of wet sulfuric acid

    (WSA) plants, meaning that up to 99.7

    percent conversion can be achieved insingle contact WSA plants. VK-WSX™ is

    installed in several WSA plants.

    The VK38™ 25 mm Daisy dust

    protection catalyst allows bigger penetration

    depth of dust particles into the 25 mm Daisy

    layer. The resulting higher dust capacity

    yields significant savings in blower energy

    and allows plants to lengthen the campaign

    compared to standard size catalyst.

    After installing cesium catalyst, our

    VK-701 LEAP5™ is the next step for

    achieving even higher conversion. VK-

    701 LEAP5™ uses the new LEAP™

    technology to circumvent the transport

    deficiencies in the molten phase and

    improve the amount of vanadium in the

    V+5 form.

    On the technology side, the

    development of the WSA-DC™ (double

    condensation) has been one of our major

    achievements in recent years. The WSA-

    DC™ is a double condensation wet gas

    technology that allows combining the high

    energy efficiency of the WSA technology

    with very high SO2  conversion efficiency

    of the double contact principle. WSA-

    DC™ plants can be designed for as high as

    99.99 percent conversion efficiency.

    oc  For higher efficiency, the company

    has been developing technologies such as

    Outotec® LUREC™ strong gas processing

    technology and Outotec®  HEROS™

    low pressure steam heat recovery. To

    increase lifetime, Outotec has also worked

    on equipment such as stainless steel

    converters, CORD™ gas heat exchangers

    and SX™ solutions. Our goal is to make

    sure that we are always ready to respond to

    changing requirements.

    noraM e

    Cscs  NORAM has also brought several

    new technologies to market over the last

    two decades. One of these products is the

    NORAM HP™ (High Performance) low

    pressure drop ceramic saddles packing.

    By choosing NORAM HP™ packing,

    clients can debottleneck their acid plant

    and increase production rate or reduce

    energy consumption. HP™ packing has

    been proven to reduce pressure drop across

    the packing in acid towers and increase gas

    flow throughput in the tower by 25 percent.

    NORAM has also developed the Split

    Flow™ radial flow gas heat exchanger to

    address problems of corrosion in cold gas

    exchangers due to condensation of the gas

    at cold zones of the exchanger, typically at

    the bottom tube sheet. For more than 15

    years this patented product has improved

    the reliability and life-cycle of cold gas

    heat exchangers, SO3  coolers, pre-heaters

    and tail-gas re-heat exchangers.

    NORAM’s pipe-type acid distributors

    have also been well received by the

    industry because of their low cost and easy

    installation. These distributors promote

    uniform acid distribution into the packing

    as no leveling is required, unlike that of

    competitor products. Additionally, the

    design features external access ports, which

    provide added safety to service personnel.

    Cmcs  Although Chemetics was the first

    to introduce silicon stainless steels

    (SARAMET®  alloy) to the industry in1982, the 1990s and early 2000s were a

    period of acceptance by industry for this

    alloy in all strong acid systems—towers,

    tanks, distributors and piping—over

    traditional brick lined vessels and cast iron.

    Chemetics improved its mechanical designs

    and modernized its fabrication facilities

    to meet the increasing competition from

    global sourcing. We have led in the supply

    of modular gas exchangers and stainless

    steel converters to lower the overall costand risk for overseas projects. As the acid

    plants have been getting bigger, we have

    continued to lead in the development of

    acid coolers, pushing the limits of cooler

    size, water and acid temperatures while

    ensuring reliability.

    ac Pp tcy  In addition to completing severalmajor projects around the globe, including

    the U.S., Australia, Morocco and Jordan,

    Acid Piping Technology (APT) has

    improved the options available to plants in

    a number of ways.

      Mondi™ piping alloy has undergone

    major improvements in metallurgy and

    casting techniques. Thanks to these

    improvements, piping will now last the life

    of the acid plant.

      APT has partnered with ASC ValveCompany to provide excellent gas duct

    valves and jug valves at competitive prices.

    ASC is one of the few, perhaps only,

    manufacturers offering tight shutoff, high

    temperature, low pressure valves.

      In recent years, APT has also

    developed low pressure drop, high

    efficiency tower saddle packing.

    Kc K llC  Koch Knight has challenged the

    market by producing multiple product

    advancements over the past 20 years with

    the introduction of our PYROFLEX™

    acid resistant sheet lining 500 for tower

    membranes, FLEXERAMIC™ ceramic

    structured packing for more efficient mass

    transfer, LPD™ random packing for lower

    pressure drop in towers and advancements

      Magma Metal Co. ofSan Manuel, Ariz., made itsmark on the industry as a rapid-fire turnaround facility. Withcomplete turnarounds taking

    place at 15-month intervals,the company fine-tuned itsturnaround procedures to makethe necessary events both safeand efficient.  At the time, Magmawas producing 1 million short

    tons of 100-percent sulfuric acid per year, making it oneof the largest one-site producers of smelter acid in theUnited States.

    Company Update

    In 1995, The Broken Hill Proprietary CompanyLimited (BHP) acquired Magma Metals for $2.4 billion.  Prior to its shutdown in 1999, Magma’s operat ionin San Manuel was the largest operating undergroundcopper mine in the countr y.  In 2006, the Magma Metals plant was dismantledand sold. The two remaining smokestacks were toppled

    in January 2007.

      In June 1995, following

    three years of planning andengineering, Kennecott UtahCopper Corp. brought theworld’s largest metallurgicalsulfuric acid plant online justoutside of Salt Lake City at

    the Bingham Canyon Mine.This modern facility replaceda previously existing plant,which was shutdown in May

    1995.  The 3,860-ton per day plant was designed andconstructed by St. Louis-based Monsanto Enviro-Chem(now MECS Inc.).

    In addition to its economic attributes, the new

    facility also garnered attention as one of the most

    environmentally sensitive plants in the world. The

    MECS design included reductions of sulfur dioxide

    emissions from around 17,000 tons per year to less than

    1,000 tons per year.The facility was also the first to feature MECS’

    new HRS system that helps capture and recover energy—

    around 24 megawatts on a n average production basis. In

    addition, it was the fi rst to use two HRS towers.

    Company Update

      In April 2013, a landslide occurred at the mine. It

    was the largest non-volcanic landslide in the history

    of North America. Around 65-70 million cubic meters

    of dirt and rock thundered down the side of the pit.

    Mining operations were shut down the previous day in

    anticipation of the slide. The massive slide is expectedto cut the production of the mined copper by 110,000

    short tons. A second slide caused an evacuation of 100

    workers on September 11, 2013.

      In addition to producing about 300,000 tons of

    copper a year, the Bingham Canyon Mine also produces

    approximately 400,000 ounces of gold; 4 million ounces

    of silver; 30 million pounds of molybdenum; and 1

    million tons of sulfur ic acid annually.

      First started over a

    century ago, the Asarco Inc. El

    Paso, Texas, facility was one

    of the nation’s oldest copper

    smelters.

    Originally built to

    handle ore from Mexico, the

    site consisted of two sulfuric

    acid plants—a 1972 Lurgi

    (575 tons per day) and a 1978

    Monsanto (1,050 tons per day).

    In the mid-1990s, theonset of stricter environmental standards prompted

    Asarco to monitor the heat exchangers for potential

    leaks that can increase emissions. In 1996, if a plant’s

    sulfuric acid emissions exceeded 600 parts per million,

    it was shut down. If a facility lost a heat exchanger due

    to a few leaking tubes, the amount of tai l gas would shut

    that site down. To determine a lea k, acoustic monitoring

    equipment must be utilized inside the exchanger. But

    accessing the exchanger requires a cool down process

    that can ta ke days.

    To save both time and money, Asarco called on VIPInternational (VIP) of Baton Rouge, La., and its high

    temperature entry process. VIP’s high temperature entry

    virtually eliminates the exchanger cooling process. VIP

    can usually enter after only four hours of cooling.

    Once inside, VIP uses acoustic emissions equipment

    to spot the leaks, and can have them plugged long before

    the conventional process would even begin.

    Company Update

    The Asarco El Paso, Texas, smelter was idled inFebruary 1999 due to hi storically low worldwide copperprices and the closure of several copper mines.

    In its last full year of operation, the plant produced120,320 tons of copper. When the plant was fullyoperational, it provided about 400 high-paying jobs andhad a direct and indirect impact on the local economy ofabout $300 million an nually.  Asarco was acquired by Grupo Mexico in November1999. With the purchase of Asarco, Grupo Mexicobecame the third largest copper producer in the world.Asarco is a subsidiary of Grupo Mexico Sa de CV. InApril 20 01, Asarco suspended operations i n East Helena,

    Montana.In 2005, Asarco filed for Chapter 11 bankruptcy.

    In 2009, Asarco emerged from bankruptcy and re-integrated into Grupo Mexico, deciding not to reopenits El Paso smelter. In December 2009 Asarco signedan agreement guiding the course of the environmentalcleanup of the El Paso 400-acre smelter, which willbe lead by the Texas Commission on EnvironmentalQuality. Cleanup of the site began in 2010 and the tworemaining smokestacks were demolished in April 2013.

    Completion of the cleanup is targeted for 2015.

      In the short span of

    a decade, Potash Corp. of

    Sasktachewan (PCS) hashelped change the future of

    the fertilizer industry. Througha managerial philosophythat embraces growth and

    change, PCS has built acompany of quality reserves,quality operations and quality

    employees, which continues to be further enhanced bynew acquisitions.

    In March 1997, PCS acquired Memphis, Tenn.-

    based Arcadian Corp. T he company’s integration into the

    PCS structure created a fertilizer empire unparalleledin quality and service capabilities. It cemented PCSas the No. 1 nitrogen producer in the U.S. and the

    second worldwide, and enabled the company to buildconnections among subsidiaries and develop synergiesthat enable it to better serve its clientele as a one-stop-

    shop. What was once a potash-only corporation is nowset for the 21st century as a powerhouse in the potash,phosphate and nitrogen fields.

    At the helm of the PCS metamorphosis is Chairma n,President and Chief Executive Officer C. E. Chi lders. A40-year industry veteran, Childers joined PCS in 1987.

    He brought with him a clear-cut vision of the industry’sfuture. He led the company through privatization in1989, bringing a return to shareholders of more than 500

    percent.Childers’ foresight helped prepare the company for

    the rising world population and the growing demands on

    economies and farmers.

    Company Update

      Over the last several years, PCS has continuedto invest in its operations by completing potashdebottlenecking projects at its Canadian facilities

    in Rocanville, Allan, Lanigan and Patience Lake.Expansion projects have also been completed at Allanand Cory, and Aurora, N.C.  The company has also been enhancing its portfolio

    through corporate acquisitions. In 1999, the companyacquired Minera Yolanda SCM, a specialty potashproducer in Chile, for $37M. In addition, PCS has

    been purchasing increasingly larger stakes in Sociedad

    Quimica y Minera de Chile (SQM), Arab Potash

      Throughout its 115-yearhistory as part of the coppermining industry, Phelps DodgeCorp. has evolved into oneof the world’s largest copperproducers, while never straying

    from the belief that being agood business goes hand-in-hand with being a goodneighbor.  Since its inception in

    the 1830s, Phelps Dodge has placed environmentalresponsibility at the heart of its mining operations. Astimes, products and people have changed, those idealsset forth by the company founder, Anson Greene Phelps,have never faltered.

    Phelps Dodge entered the copper mining businessin 1881. As part of the government’s requirements

    placed upon copper miners and their sulfur emissionsregulations, Phelps Dodge operates three sulfuric acidplants for use with its copper smelting business. Theproduction of acid is essential to t he smelter operations.

    In 1998, Phelps maintained two smelter operations – the Chino Mines Co. a nd Phelps Dodge Hidalgo I nc.The Hidalgo site runs two acid plants to keep up with itscopper smelting.

      Phelps Dodge has found an alternative to the

    transport and disposal of its sulfuric acid with thedevelopment of an internal consumer through its mine-for-leach operations. The leaching process requires theacid, so the two operations serve as a p erfect complement.

      As one of the world’sleading manufacturers anddistributors of fertilizerproducts, CF Industries Inc. hascarved a unique niche for itselfas a consistent, unchangingface in a rapidly consolidatingindustry. The company’s

    Florida Operations—whichinclude four sites at Bartow,Plant City, Hardee and the

    Port of Tampa—serve as the base of all the company’sphosphate mining, manufacturing and distribution.

    The four facilities within the Florida Operationshave been bolstered by CF’s unusual structure as acorporate entity owned by farm supply cooperativesthroughout the United States and Canada. The Floridasites work in tandem to mine, manufacture and distributethe necessary nutrients to CF’s cooperative owners. Thisco-op arrangement has been the saving grace for CF

    during market ups and downs. With a built-in market,operating at capacity is always cost-effective.  Production levels at CF are at an all-time high.Bartow produces between 1,000 and 1,100 tons per dayand Plant City generates as much as 7,000 tons per dayon average. In March 1999, Plant City levels reachedrecord-setting status with a 100-percent operating factoron all acid plants.

    Company Update

      CF Industries Florida Operations has always beena stellar example of production and safety for the

    industry as a whole. In September 2003, the companywas recognized for its efforts and was named one ofAmerica’s Safest Companies by Occupational Hazards magazine. To earn that title, CF achieved over 6 millionsafe work hours at the Plant City Complex in late 2003.  In 2005, CF Industries Inc. initiated an initial publicoffering as the final step to establishing CF IndustriesHoldings, Inc. as a public company.

    Continuing their quest to become a nitrogenbellwether in the global fertilizer industry, in 2010 CFIndustries acquired Terra Industries Inc. Th is positionedCF Industries as the premier nitrogen and phosphate

    fertilizer manufacturer in North America, the secondlargest nitrogen fertilizer producer in the world and thethird la rgest phosphate fertilizer producer among publiccompanies.

    In late 2013, the Mosaic Co. announced anagreement to purchase CF Industries for $1.4 billion.Under the deal, CF Industries agreed to sell the HardeeCounty phosphate rock mine; the Plant City phosphate

      Dedicated to producinga cost-conscious product whileremaining a valiant defenderof the unique environmentin which it thrives, SFPhosphates Ltd. Co. hasproved a shrewd competitor

    in the fertilizer industry. Thecompany’s operations consistof two facilities that work inconjunction with one another

    to create a strea mlined, cost-effective system.  The Vernal, Utah, site is home to the company’smining operations while the Rock Springs, Wyo.,location is home to the company’s fertilizer plant. Thetwo sites are connected with a 10-inch slurry line thattransports the phosphate concentrate over the UintahMountains to Rock Springs, some 96 miles away. Thepipeline, constructed by predecessor Chevron, has

    freed the company from the reliance on other formsof transportation that are often affected by inclementweather in the region.

    Two sulfuric acid plants power the Rock Springsoperation. The first, a Lurgi model, produces 1,900short tons per day. The more recent plant, brought onlinein 1995, is a 1,250 short tons per day Monsanto model.Prior to its installation, SF had been purchasing itssulfuric acid to supplement the plant’s production.

    Two finished products are created at SF’s facilities—super phosphoric acid and MAP. Resources producedinternally, such as the sulfuric acid and the phosphate

    rock mined at Vernal, help keep SF’s production costs toa minimum.

    Company Update

      In late 2003, the J.R. Simplot company purchasedFarmland’s interest in the SF Phosphates venture forapproximately $64.5 million. The manufacturingfacility at Rock Springs, Wyo., and the phosphate mineat Vernal, Utah, are now a Simplot-only enterpriseknown as Simplot Phospahtes. For an update on SimplotPhosphates, see  J.R.

    community.Founded in 1907 by two aspiring German

    entrepreneurs, Rohm and Haas branched out to theUnited States in its first decade. In the 1920s, thecompany moved to specialty chemicals. Innovations inacrylic chemistry and the creation of Plexiglas helpedbolster company profits and reputation.

    In the late 1940s, Deer Park set up shop along theHouston Ship Channel. Today, the site is one of the most

    productive in the company’s network. Central to the siteis a sulfuric acid plant that produces more than half-a-million tons of sulfur ic acid each year.

    Company Update

    Consolidation has been a major factor in the sul furicacid industry over the past 20 years, and Rohm and Haasis no exception. In 2009, Dow Chemical Company boughtRohm and Haas for $15 million. Today, Dow Deer Parkoccupies 700 acres along the Houston Ship Channel, andemploys nearly 790 people within eight production areasthat operate as separate facilities or “plants within aplant.” The myriad of specialty chemicals manufacturedat the site include methyl methacrylate, acrylic acid,amines and various acrylates.

      Mississippi PhosphatesCorp. is ideally located fordomestic and internationalbusiness along the coastalwaters of the Gulf of Mexico.The company has blossomedas a successful industrial

    enterprise with a corporatephilosophy that is more aboutfamily and roots than bigbusiness and bottom lines.

    In the mid-1950s, the company moved toward theGulf Coast area to combine all three primary plantnutrients—potassium, nitrogen and phosphate. Some40 years later, following a variety of acquisitions,mergers and overhauls, Mississippi Phosphates is nowa 250-person strong company, producing 900,000 tonsof DAP per year. The site has a 70,000-ton storagecapacity, and its close proximity to a port at Pascagoulaenables the company to ship at a rate of 8,000 tons ofproduct per day.

    Presently, there are two Lurgi sulfur ic acid plants inoperation on the site. Both were original ly 1,500 tons perday plants. Upgrades and the addition of low-pressurecatalyst have pushed the plants to 1,750 tons per day.

    Mississippi Phosphates combines its homegrownsulfuric acid with internationally imported Moroccanphosphate rock to create its quality product. Close

    proximity to the southern Mississippi port and the high

    quality of the imported rock made the decision an easyone. With the finely milled Moroccan rock, Mississippi

    Phosphates only has to run one mill to prep the resourcefor production.

    Company Update

      In June 2003, Mississippi Chemicals voluntarilyfiled for a Chapter 11 reorganization. The companydetermined that this choice was the best for the long-

    term interests of t he company and its stakeholders.In 2005, Terra Industries Inc. purchased the

    nitrogen side of the business for $268 million, including

    assumed debt. In 2010, Terra Industries was acquired byCF Industries for $4.7 billion. The combined companybecame the second largest nitrogen fertilizer producer in

    the world. CF Industries and Terra have complementarystrengths in nitrogen, providing breadth and flexibilityin product offerings. In addition, the locations of CFIndustries’ and Terra’s facilities together expand thecombined company’s domestic reach.  The phosphate side of the business emerged from

    Chapter 11 proceedings as Mississippi Phosphates Corp.MPC’s manufacturing facilities at Pascagoula includethe two Lurgi sulfuric acid plants, a phosphoric acid

    plant and a DAP granulation plant. The DAP granulat ionplant has a maximum annual production capacity ofapproximately 850,000 tons. The existing sulfuricacid plants have the capacity to produce sulfuric acid

    sufficient for annual DAP production of approximately600,000 to 640,000 tons. The company has been plaguedin recent years by a string of safety violations, includingthe deaths of two workers.

    In January, the company announced that it willadd monoammonium phosphate (MAP) to its product

    line, beginning this spring. The addition of MAP tothe MPC product portfolio will allow the company

    to take advantage of broader market opportunities. Inbroadening its product mix, MPC will combine internalmarketing efforts with an exclusive off-take agreementfor MAP with Interoceanic Corporation (IOC), ofOssining, N.Y., in an effort to enhance its targeting of

    value-added market sectors.

    and made the product a commercial success through its

    applications in the aviation industry.  Following World War II, INEOS was forced toseek new applications for MMA and PMMA. Today the

    marketplace abounds with distinctive products includingappliances, paint, inks, adhesives, lubricants and textiles.

    At each of INEOS’ five MMA plants, a sideprocess stream of weak acid is produced. The stream is

    processed by burning the acid, reconstituting the freshacid and then reworking it back into the plant as oleum.That oleum is then utilized to create methacrylamide.

    Each of INEOS’ five plants also houses a sulfuric acidregeneration (SAR) unit that together supply acid to

    worldwide markets.

    Company Update

      In May 2002, INEOS Acrylics changed its name toLucite International to better align the company withits top brand: Lucite. In 2009, Lucite International was

    acquired by Mitsubishi Rayon Co. Ltd., creating theworld’s largest supplier of MMA. Already a well-knownname throughout the Americas, Lucite has a growingpresence in Europe and other a reas of the world.

    Over the past 15 years, Lucite International hasfocused on innovation. The company developed Alpha

    technology, a new, patented route to MMA based onreadily available raw materials including ethylene,methanol and carbon monoxide. The first Alpha plant,a 120,000 metric tons per year facility in Singapore,became fully operational in 2007. Plans are in the works

    for two more Alpha sites.  Lucite International was also the first MMAproducer to successfully adopt a three-year overhaulcycle, which continues to release additional capacity

    from existing assets.  Lucite Internationa l’s focus on novel research intocatalysis and new processes has won the company

    several awards, including the 2009 KirkpatrickChemical Engineering Award and the Chemical IndustryAssociation (CIA) 2009 Innovation Award.

      From humble beginningsin the 1920s to its present

    status as a major agribusiness,the J.R. Simplot Co. has beenan ever-changing reflection

    of the times and technologiesthroughout its 80-plus yearsin business. Company founderJ.R. “Jack” Simplot recognized

    the inevitability of change, andhe used that k nowledge to grow

    his one-man operation to a major agribusiness, currentlyemploying over 9,000 people.

      In the mid-1940s, Simplot’s livelihood was threatenedby the diminishing supply of phosphate fertilizer. Toensure a long-term supply for hi s agribusiness, Simplotfounded his flagship fertilizer production facility in

    Pocatello, Idaho. Soon after the Don Plant went onlinein 1944, the Simplot name became synonymous with theprocessing of agricultural assistance products.  The Don Plant is joined in its production of fertilizer

    by two sites state side in central California. An additionalfacility is operated under the Simplot Canada Ltd. name,headquartered in Brandon, Manitoba.

    The Simplot family of fertilizer producers expanded

    once again in 1992 when Simplot and Farmland Industr ies

    created a joint venture known as SF Phosphates Ltd. Co.Whenever the times have been hardest and the markets

    have been their bleakest, Simplot Co. has relied upon the

    wisdom of the company founder to guide it through. Byenacting a policy of low costs and high assets, Simplotturned his small farming entity into a global enterprise.

    Company Update

    The Simplot Company suffered a great loss withthe death of founder J.R. Simplot in May 2008. Thecompany has carried on, though, led by four members

    of the Simplot family who comprise the executive

    committee of the company’s board of directors. Theyhave continued his tradition of plowing profits back

    into the enterprise, responsibly advancing J.R. Simplot’slifelong mission of bringing Earth’s resources to life.

    From 2002-2005, Simplot paid several fines tothe EPA for unreported release of sulfur dioxide at the

    Don Plant, among other things. Since then, though, thecompany has redoubled it’s efforts at environmentalstewardship.

    Simplot is one of six major companies to join the

    Obama Administration in an effort to significantlyreduce energy use over the next 10 years. The company

    has received a number of awards, including the stateEarth Day award for environmental work completed

    in Nevada, and a star award for outstanding safety andhealth results over the last 5 years.  In June 2012, Simplot partnered with twoconservation groups in an effort to improve the water

    quality of the Blackfoot River in Eastern Idaho. Theconsortium includes J.R. Simplot Company, Monsantoand Agrium/ Nu-West Industries, the Idaho Conservation

    In central Florida, the company manages fourphosphate mines—Four Corners (the largest mine inthe world), Fort Green, Kingsford and Hopewell. Thecompany also operates two chemical process units—one

    at New Wales and one at South Pierce. The New Walessite is the largest concentrated phosphate plant in theworld.

    New Wales is a vast and complex facility. It is home

    to five large sulfuric acid plants, three phosphoric acidplants and granular plants. On a typical day the sitebrings in around 20,000 tons of rock, 4,500 tons of

    sulfur and 2,400 tons of ammonia. Railcars and trucks

    leave the site daily with 13,000 tons of fertilizer and

    2,500 tons of animal feed products.The Louisiana leg includes operations at Uncle Sam,

    Faustina and Taft. Both Faustina and Taft were subject

    to closures, the later permanently, during major industrydownturns.

    Company Update

    In 2004, Cargill joined forces with IMC to createMosaic Co. The new venture provided customersaround the globe with a more diversified product mix,including all three of the world’s primary concentrated

    crop nutrients: phosphate, potash and nitrogen. For

      In its 80-plus year

    history, Newmont Mining Cor p.has been a stellar reflection ofthe company’s clearly stated

    directive—creating value withevery ounce.

    A global force in thegold industry, Newmont is the

    world’s largest producer ofthe precious metal. Newmontoperations and assets dot the

    planet and include five continents, 87 million ounces

    of long-lived reserves and roughly 94,000 square milesof territory in the world’s best gold districts. Newmontcomplements its impressive catalog of resources withinvestments in technology, ensuring the greatest gold

    recovery rates.Since the first discovery of the colossal Carlin Trend

    in 1961, Newmont has maintained a strong presence inthe Nevada mining territory. The company’s current

    operations include nine open pit mines, five undergroundmines and 15 processing facilities.

    Remaining the leader in gold production requires

    that Newmont rely on the latest technology for obtainingand refining its product. The company incorporates all ofthe advanced processes—leaches, oxide mills, flotationplants, autoclaves, roasters and bio-oxidation—to create

    an impressive ore blend.As an offshoot to t he efficient extraction processes,

    Newmont is left with an extensive waste stream of SO2.

    As a conscientious member of the community and adedicated environmental steward, Newmont constructeda sulfuric acid plant at t he back end of Mill 6. This highlyeffective, profit-saving method for re-using Newmont’s

    waste has also boosted the plant’s profit margin. Thecompany uses the sulfuric acid for cost-saving on site(as part of the cyanide detoxification process) and profitraising off site (as a supplier to other gold producers).

    Company Update

      Newmont’s mining operations in Nevada haveexpanded over the past 20 years. Operations now

    include 14 open-pit and four underground mines and14 processing facilities. The properties operate as anintegrated unit, and together, they boast the widestvariety of processing methods of any gold mining

    complex in the world.  In 2013, Newmont expanded its scope of operationsat the Phoenix gold mine, near Battle Mountain. The

    company began recovering copper from gold-mining

    solution to dissolve the copper. Roughly one-third of theacid used is currently produced on-site. Production in

    2013 was around 5 million pounds of copper, with anestimated annual production rate of 20 million poundsper year for the first five years of full-scale operation.

      The company also has a long-standing dedication tosafety. The Carlin Surface Mine rescue team won the titleof 2013 Overall Champion at the National Mine Rescue

    Championship, the first team from Nevada to do so.
