The preparation process is designed to produce a small, representative and homogeneous sub-sample from the material you submit to the laboratory. Sample preparation schemes are available to suit most purposes but can also be readily customized to suit any particular project requirement. ALS Minerals staff are accustomed to adapting to specialized procedures and are very aware of the significance that variations in certain steps can have on analytical outcomes.

In particular, it is helpful to advise us of mineralized samples that require special handling or special equipment cleaning cycles to eliminate contamination of other samples that might follow in a batch.

Sample Pick-up ServicesSample transportation /pick-up services can be arranged from any of our locations. Please contact your nearest ALS office for details.

Accurate results begin with representative samples. Meticulous care is taken in the collection of geological or other samples to provide representative samples to the laboratory. Following sample collection, appropriate laboratory sample preparation protocols must be selected with care to produce the desired homogeneous subsample for analysis. ALS Minerals approaches sample preparation with the same rigorous quality control procedures and careful attention to detail as any other stage of analysis.

Sample Submission Please send your samples to any of the addresses on our website and those listed on the back cover page of this document. Pre-addressed adhesive labels and sample submission forms are available on our website and can be sent to you on request as well. We can also offer advice on shipping your samples to any of our laboratories by surface carrier, air cargo and air express.

Detailed information on requirements and regulations for each jurisdiction are on the website.

Sample TrackingALS Minerals is very aware of the value of your samples. Confidence and security in the chain of custody for your samples as they pass through our system is obviously very important. To provide complete traceability your samples are logged into our proprietary world-wide laboratory information management system and given a barcode at log-in. A per sample fee is applicable and is included in the “Sample Preparation Packages” quoted on the following page. We encourage clients to barcode samples prior to sending them to our laboratories. In such cases we will work with your barcodes. Alternatively, we can attach an ALS Minerals system barcode as your samples are received.

Screening

Screening is performed where a sample needs to be separated into size fractions. Mesh sizes can be specified and custom multiple-screening procedures are available.

Splitting

Some samples may require splitting into representative subsamples. In many locations automated rotary splitters can be attached to crushers to produce demonstrably superior precision in sub-sample analyses. The addition of rotary splitting eliminates one of the largest systemic sources of error in the production of a sub-sample for analysis.

Pulverizing

All pulverizing procedures make use of “flying disk” or “ring and puck” style grinding mills unless otherwise specified. Grinding procedures guarantee that, for most sample types, at least 85 percent of the sample material will be pulverized to 75 micron (200 mesh) or better.

Pulverizing bowls are made from a low chrome steel. Other bowls are also available for non-metallic sample preparation (i.e. tungsten carbide, agate , zirconia etc.). Please enquire if interested in non-metallic pulverization media.

Crushing

Jaw crushers may be used where samples are too coarse to be put directly into a large pulverizing mill, or where particle size must be reduced prior to splitting.

individual Sample Preparation ProceduresThe following procedures are used either separately or combined in a package in order to meet specific needs. Most of these procedures are charged at a rate that is based on sample weight.

Drying

Drying charges are only applied to samples that are excessively wet. Local laboratory managers will determine the applicability of such charges in consultation with the client, when the samples are received.

Specific Gravity & Bulk DensitySpecific Gravity and Bulk Density of ores is often under-characterized in the determination of tonnage and grade of a deposit. Incorrect assumptions or inadequate characterization of this basic rock property has lead to gross errors in the estimation of deposit tonnage and grade in several instances.

Specific gravity on solid objects is calculated by the difference in weight of the object in air and in water. Depending on the fractured or porous nature of the sample, a wax coating may be necessary. The result is expressed as a ratio of the sample’s weight with respect to an equal volume of water. Common rock samples are typically about SG 2.6. SG analysis on pulps is carried out by placing 3g of pulp into a pycnometer, which is then filled with a solvent. The calculation is made using the weight of the sample and the weight of the displaced solvent.

Bulk Density analysis on solid objects is carried out by weighing the object, then slowly placing it into a bulk density apparatus which is filled with water. The displaced water is collected into a graduated cylinder and measured. The BD calculation takes into account the weight of the sample and the volume of water displaced; the result is expressed as g/cm3. BD may alternatively be calculated from SG data.

Calculations for SG and BD are corrected for air temperature and the density of the wax coating, if a wax coating is used.

Gold and other precious metals continue to be highly sought after by mining and exploration companies worldwide as a result of their strong prices in recent years. ALS Minerals has the analytical tools and years of experience to help you with this potentially valuable search.

Selection of the best method for the accurate determination of precious metal content in a sample is highly dependent on the nature of the sample matrix, the grain size and distribution of the precious metals of interest and the objective of the analytical result.

Gold

Fire Assay Fusion

For quantitative analysis of gold, the fire assay procedure is still the preferred choice globally. However, it should also be recognized that a wide variety of minerals and metals such as chromite, base metal sulfides and oxides, selenides and tellurides in moderate to high concentrations, can interfere with the fire assay process, generally leading to low precious metal recoveries. With prior knowledge of the presence of these minerals and metals, ALS Minerals can modify flux constituents and increase flux to sample ratios to improve recoveries. In most cases, a reduction in sample weight will yield higher precious metal recoveries, particularly in the presence of the interfering species mentioned above. For optimum gold and PGE recoveries for most sample matrices, ALS Minerals recommends a 30g maximum charge weight.

Aqua Regia Gold Digestions and Multi-Elements Determinations

Aqua regia digestion is generally suitable for the determination of gold in soil and stream sediment samples. Where this digestion procedure is used to measure the acid extractable gold content of rock chips and other more mineralized materials, roasting of samples containing sulfides and/or carbon prior to analysis is recommended. A 15g sample is often sufficient for soils. For stream sediments, the large 50g nominal weight and lower detection limit is recommended.

Adding ME-MS41 to an Aqua Regia Gold Digestion

Many projects require the full multi-element suite from the ME-MS41 (page 13) plus a larger sample size for Au to reduce potential nugget effects and provide the lowest possible detection limit. ME-MS41 can be combined with our Trace Level and Super Trace Level aqua regia gold digestions to provide a larger sample size and the full multi-element information.

A 15g sample is often sufficient for soils. For stream sediments the large 50g nominal weight and lower detection limit is recommended.

Exploration geochemistry utilizes trends and patterns in trace elements as indicators of what may lie deep below the surface or at great distance from the current location. More and more often, today’s explorers require lower detection limits and a wider range of elements to identify prospective targets.

The effectiveness of a geochemical exploration program is largely dependent on the availability of analytical methods that properly meet the requirements of the problems at hand. Element coverage, detection limits, reliability and cost are often the main factors considered by explorers when choosing an analytical method for a given sample type.

ALS Minerals offers a wide range of multi-element and single-element methods that can satisfy the requirements of today’s exploration geochemists, both technically and economically. The analytical methods described in this section include different sample decomposition procedures, such as aqua regia and multi-acid digestions, fusions and selective leaches. The instrumental analytical techniques include inductively coupled plasma with atomic emission spectroscopy or mass spectroscopy, atomic absorption, x-ray fluorescence and infrared spectroscopy.

Ultra-Trace Level Methods Using ICP-MS & ICP-aeS

Aqua Regia Digestion with Ultra Low Detection Limits for Soil and Sediment Analysis

The aqua regia digestion and a combination of ICP-AES and ICP-MS, with sophisticated software and careful analysis, allows a low detection limit, multi-element package useful for exploration in areas requiring ultra-trace analytical sensitivity, such as soil or sediment surveys. The recovery for many analytes from more resistive minerals may be low. The method uses a sample size of 0.5 grams. Coarse and malleable minerals such as native gold and silver are not representatively characterized by such a small sample. In these cases fire assay or the super-trace aqua regia methods described on pages 8 and 9 may be preferable.

Aqua Regia Digestion

Although some base metals may dissolve quantitatively, in the majority of geological matrices, data reported from an aqua regia leach should be considered as representing only the leachable portion of the particular analyte. The recovery percentages for many analytes from more resistive minerals can be very low, but the acid leachable portion can also be an excellent exploration tool.

In order to report the widest possible concentration range, this method uses both the ICP-MS and the ICP-AES techniques. Minimum sample size is 1g.

Four Acid “near-Total” digestion

Although the four acid digestion is able to dissolve most minerals, it may sometimes be necessary to use even stronger dissolution techniques such as fusions in order to get fully quantitative results. However, in most cases this procedure quantitatively dissolves nearly all elements for the majority of geological materials.

In order to report the widest possible concentration range, this method uses both the ICP-MS and ICP-AES techniques. Minimum sample size is 1g.

Trace Level Methods Using Conventional ICP-aeS analysis


An economical tool for first pass exploration geochemistry. Again, although some base metals may dissolve quantitatively in the majority of geological matrices, data reported from an aqua regia leach should be considered as representing only the leachable portion of the particular analyte. Minimum sample size is 1g.

Add-on Elements to a larger (25g or 50g) Aqua Regia Gold Digestion

Following an aqua regia gold digestion (method Au-ST43 or Au-ST44 - see page 9), an aliquot can be analyzed by ICP-AES to give additional information for acid leachable elements. The method below is an alternative way of obtaining additional multi-element data in conjunction with gold when ultra-low detection limits are not crucial.


Four acid digestions are able to dissolve most minerals and although the term “near-total” is used, not all elements are quantitatively extracted in some sample matrices. Minimum sample size is 1g.

The procedures listed below are designed to provide optimum results for each ore type or product. This includes the specific digestion procedure, calibration protocols and the use of appropriate Certified Reference Materials for each sample type. For large projects or regular submissions of certain products, where a broader element suite or lower detection limits are required, ALS will consider customising methods to suit individual needs. evaluation of Ores & High Grade Materials

The methods described in this section are suitable for most ores and high grade materials. Depending on the purpose of the analytical results, concentrations greater than 15%-20% may require the use of more expensive methods, such as titrimetric and gravimetric analysis, in order to achieve the maximum accuracy. Please contact your nearest ALS laboratory should you require this type of analysis.

For characterization of ores, recommended procedures include; the aqua regia digestion (OG46) primarily for lead/silver/zinc rich ores and four acid digestion method (OG62) for copper and zinc ores with low lead and silver and nickel laterite ores. Samples expected to contain significant amounts of sulfides of copper, nickel and/or cobalt are fused with sodium peroxide and then leached with dilute hydrochloric acid using procedure ICP81. High grades of elements difficult to solubilize or maintain in solution, such as barium, tungsten, are best done by XRF. The mineralogy of the sample as well the elements to be determined should be considered when selecting an assay procedure.

Acid Digestions

Aqua regia digestion is a powerful solvent for sulfides, which dissolves Ag and the base metals but the resistive mineral forms are not completely dissolved.

Four Acid Digestion, using HF, is a very strong digestion method which almost completely breaks down silicates which are volatized as SiF4. The digestion will decompose all but the most resistive minerals.

While analytical methods for geochemical exploration are optimized for low detection limits, the assays for evaluation of ores and high grade materials are optimized for accuracy and precision at high concentrations.

Fusions

Sodium peroxide fusions are effective for the decomposition of sulfides, arsenides and many refractory minerals such as chromite, rutile, ilmenite and titanite. It is the method of choice for nickel sulfide deposits.

XRF analysis is the preferred method for highly resistive elements. A homogenous glass disc is prepared by fusion, eliminating mineralogical effects. It has particular applications for resistive minerals and the determination of elements that are difficult to decompose and retain in stable solutions at high concentrations

iron Ore ProceduresX-Ray Fluorescence (XRF) is the method of choice for analysis of oxide iron ores throughout the industry. The lithium borate fusion technique coupled with XRF, offers a robust and repeatable method, consistent with industry requirements. The relatively low flux to sample ratio offers good sensitivity for the majority of elements and creates a matrix which is not subject to particle size effects. With very few spectral interferences and high instrument stability, the XRF method delivers highly accurate and precise results across the full range of iron oxide ore types.

Loss on Ignition (LOI) is a critical component of iron ore analysis, providing a better understanding of mineral composition of the ore and how it will behave during processing. Single temperature or multi temperature LOI determinations are available. Temperatures can be customized as required.

Iron Ore represents a large proportion of the world’s bulk mining and exploration activity. In its metal form, iron constitutes 95% of all metals used by modern industrialized society. Common mineral forms which are amenable to bulk mining include hematite, magnetite, goethite/limonite, siderite, chamosite, pyrite and ilmenite. The oxide mineral forms contribute the largest percentage of iron ore to global production.

The preparation of magnetite rich ores requires a rigid and complex protocol involving a staged wet sieving process and the use of a Davis Tube to provide a beneficiated sample that represents the large scale metallurgical process. This procedure is often very specific to the individual ore types encountered. Prior to commencement of any project it is highly recommended that clients discuss their requirements with ALS staff, to determine the optimum protocol for their particular ore type.

Aluminium Ore (Bauxite) ProceduresThe internationally recognized method for the analysis of major and minor elements in bauxite is X-Ray Fluorescence (XRF). Finely pulverized samples are decomposed using a lithium borate fusion technique and the resultant glass disc is analyzed by wavelength dispersive XRF. XRF instrumentation is extremely stable and provides high accuracy and precision. Bauxite ore is typically very hygroscopic and therefore Loss on Ignition (LOI) determination and moisture correction is an important part of the analysis. Results are reported on a dry weight (110°C) basis by default.

Aluminium is the most abundant metal element in the earth’s crust. Bauxite is the most common ore from which alumina is commercially extracted. Gibbsite, boehmite and diaspore are the predominant aluminium rich minerals which co-exist with goethite, hematite and kaolinite in bauxite ore.

Screening and Benefication

ALS Minerals can conduct multi screen sizing and subsequent analysis of the size fractions to determine the optimum screen size for bauxite recovery. ALS Minerals can also conduct the subsequent wet beneficiation using the selected single screen.

Reactive Silica and Available Alumina

The reactive silica and available alumina, determined using pressure controlled caustic leach at elevated temperature, provide important information on the economic extractability of the ore using the Bayer process.

Evaluation of copper prospects may involve the need to know more about copper mineralogy and mineral solubility for metallurgical considerations. The separation of oxide/carbonate, secondary chalcocite and primary sulfide minerals compared to the total copper are useful in determining leachability of copper in a deposit. This information can be obtained by sequential leaching of the sample and may be augmented by direct mineralogical determination using MLA applied mineralogy.

copper Procedures Copper oxide minerals such as malachite, azurite, chrysocolla and portions of cuprite and tenorite can be leached using sulfuric acid, referred to as “acid soluble” copper. Cyanide leach will dissolve the secondary chalcocite, bornite and a portion of the chalcopyrite content of the sample, while the majority of the sulfide minerals will remain in the residue analyzed at the end of a sequential leach. The mineral dissolution in each leach may vary depending on the sample matrix and specific mineralogy.

ALS Minerals provides custom methods using different leach conditions upon request.

nickel Procedures

Acid Digestion techniques

First pass exploration samples are often analyzed using method ME-ICP61 which is a four acid digestion technique with ICPAES finish. While the method has an upper detection limit of 1% for nickel, it is recommended that an ore grade method (ie method Ni-OG62) is used to re-assay nickel concentrations exceeding 0.5%, which is a typical lower cut-off grade.

ALS Minerals has developed a variety of analytical methods suitable for the analysis of nickel in laterite and sulfides. These methods have been tailored to suit the mineralization style and the specific sample type, whether exploration, resource definition or mine grade control.

Fusion techniques

The industry preferred technique for resource definition of lateritic ore deposits is X-Ray Fluorescence (XRF). A finely pulverised sample is fused with lithium borate to produce a uniformly sized glass disc suitable for presentation to the XRF Spectrometer. The comprehensive analysis of laterite ores for major and minor elements is critical in evaluating project economics and for metallurgical process control. Loss On Ignition (LOI) determination using a Thermo Gravimetric Analyser (TGA) is also an important component of the “total” analysis.

For nickel sulfide ores, a sodium peroxide fusion technique with ICPAES finish (method ME-ICP81) is recommended to replace the borate fusions typically used for lateritic ores.

In addition to an understanding of deposit occurrence, uranium exploration now also requires an awareness of the issues and hazards that might be associated with Naturally Occurring Radioactive Materials (NORM) so that these materials are dealt with in a responsible manner.

Use of lithium has migrated from the classical use in glass and ceramics to batteries for portable electronics and cars. This has led to a renewed interest in lithium as a target for exploration.

Lithium ProceduresLithium may occur with salt, carbonates, phosphates or sulfates in brines and clay sequences in evaporate deposits. It occurs within the mica pelidolite and within spodumene and clays such as hectorite, most easily substituting in many minerals for Mg. Pathfinder elements of interest may include K, Mg, B, F, Na and Ca.

Uranium ProceduresALS has standardized screening and handling protocols throughout its network of laboratories to ensure that any NORM samples received can be rapidly identified and are handled in a manner meeting all appropriate regulations with respect to transportation, workplace safety and environmental regulations.

The storage of overburden, waste rock and mine waste materials at mine sites must be carefully planned to minimize the environmental impact of mining operations. Samples may be tested to predict their acid producing or neutralizing potential, thus allowing responsible mine planning.

acid-Base accounting (aBa) ProceduresThe balance between the potential of a rock to produce versus consume acid, is measured using ABA procedures. Our static acid rock drainage tests are designed to measure the balance between potentially acid-generating or acid-neutralizing minerals in a sample. Sulfide minerals such as pyrite, pyrrhotite, arsenopyrite in mine waste material react with water and oxygen to produce sulfuric acid which may in turn leach metals from the same and introduce them into the environment. Samples with abundant neutralizing minerals such as carbonate minerals calcite and dolomite may act to increase natural pH in waters and prevent any acid and metal contribution to the environment. The calculated Net Neutralization Potential (NNP) is a predictor of whether a particular sample will generate acid over time. A number of methods have been developed with each modification an attempt to improve prediction of the acid-or neutralizing- potential of samples. The original methods described by Sobek define the amount of CaCO3, in a sample required to neutralize acid mainly generated by sulfide sulfur. The measurement introduces acid to the sample, then adds NaOH to back titrate to neutral. The Modified Sobek method evaluates the neutralization potential at ambient temperature, using a higher pH titration end point. The third method introduces hydrogen peroxide as a correction for the erroneously high neutralizing values a regular Sobek method may produce in the presence of siderite (iron carbonate), known as the Siderite Correction procedure.

Mineralogy of the sample will affect the accuracy of the ABA prediction. The presence of siderite (iron carbonate) may overestimate neutralizing potential of a sample if acid is introduced. Sulfates such as gypsum and barite will cause overestimation of the sulfur if a total sulfur measurement is used. Some samples may contain minerals which are not sulfide but which are acid-producing. There are carbonate minerals that do not neutralize the sample, as well as non-carbonate buffering minerals such as biotite and chlorite. Mineralogical knowledge of the sample is an important augmentation to the static ABA tests.

Exploration now requires methods that cover a range of concentrations from the lowest detectable levels up to percentage level concentrations.

rare earth element and Trace elements Using ICP-MSA lithium borate fusion of the sample prior to acid dissolution and ICP-MS analysis provides the most quantitative analysis for a broad suite of elements. This technique solubilizes most mineral species, including those that are highly refractory.

Mineralized rare earth Samples using iCP-MS

A lithium borate fusion is used prior to acid dissolution. High sample to volume ratios are utilized in addition to Class A volumetric glassware. Certified high grade rare earth reference materials are part of the standard protocol.

Ore Grade rare earth determinations by iCP-AeS

High grades of REEs are being encountered in many projects. There is a requirement for better precision and accuracy at these levels than is generally achievable by multiple dilutions and ICP-MS finish.

After a lithium borate fusion and acid dissolution, the sample is taken to volume and analyzed by ICP-AES. Protocols for assay determination are used to ensure suitable precision.

Exploration for deposits of rare earth elements (REEs) is booming. Due to the REEs unique ability to retain their physical properties at high temperatures, they are critical components of materials used in electronics, hybrid batteries, wind turbines and other key industries. Demand for these products will only increase the demand for REEs.

Analysis related to lithogeochemistry, alteration minerals and trace element mobility are important tools in understanding geological environments. The selections of analytical packages on this page are designed to offer comprehensive information for these studies.

The nature of lithophile elements and the matrices in which they occur require stronger dissolution procedures to separate them from the bulk matter. The most accurate results will therefore be obtained using fusion as the separation procedure or through direct analysis. X-ray fluorescence (XRF) is the preferred technique; however, ICP-AES can also be effectively used following a fusion.

Lithogeochemistry analysis Using XrF or ICP-aeS

Lithium Borate Fusion

Major element analysis can be performed by either XRF or ICP-AES. A minimum of 2g sample pulp is required. If LOI is not required, a minimum sample quantity of 0.5g is sufficient for ME-ICP06.

Complete Characterization PackageBy combining a number of methods into one cost effective package, a complete sample characterization can be obtained. This package uses the whole rock package ME-ICP06 plus carbon and sulfur by Leco to quantify the major elements in the sample.

Single element MethodsThese methods are effective options when analytical results for one or only a few elements are required. You can create your own package of elements specific to your exploration program.


Aqua regia digestion is a cost effective method for determining the acid leachable portion of elements. Sample minimum size is 1 g.


In most cases, this digestion dissolves nearly all elements for the majority of geological materials. Resistive minerals may require fusion or XRF determination for fully quantitative results.

elemental Analysis by Pressed Pellet XrF

Pressed pellet XRF is a suitable method for determining several elements that are not easily solubilized by acid digestion techniques. A finely ground sample powder (20g minimum) is mixed with a few drops of liquid binder, compressed in a pellet press then analyzed by XRF spectrometry.

Selective Leach GeochemistryMineral exploration has moved into mature terrains with the best potential often beneath deep overburden. Subtle anomalies can be detected using conventional analytical methods; however, these types of strong acid digestions are less selective and the bulk chemistry of the overburden may mask the presence of trace elements. There are a variety of partial leaches which are effective in selectively dissolving specific components of the sample, enhancing a geochemical response to buried mineralization.

ALS Minerals offers a wide variety of partial leaches to enable its clients to select the leach which is most applicable to the geochemical environment being sampled. Methods offered include, but are not limited to, Ionic Leach, modified cold and hot hydroxylamine hydrochloride and sodium pyrophosphate leaches. Leaches using other concentrations, other reagents, leach times and conditions as specified to meet particular project requirements are available upon request. Instrumental analysis is carried out using ICP-Mass Spectrometry. Please contact an ALS representative to discuss your specific project requirements.

Ionic Leach

This sodium cyanide leach is buffered to pH 8.5 using the chelating agents ammonium chloride, citric acid and EDTA. Ionic Leach enables the detection of buried mineralization using a surface regolith or soil, through the dissolution and subsequent measurement of weakly bound ions loosely attached to surface particles. The ability of this innovative leach to give close to true background detection limits makes it effective in providing geochemical contrast and targeting buried mineralization. The method requires 50 grams of sample.

Ammonium Acetate

A buffered ammonium acetate leach is used to extract exchangeable ions and carbonates. Slightly stronger than a water wash, this very weak leach targets the most weakly bound ions and may be used in sequential extractions prior to stronger leaches.

Cold hydroxylamine hydrochloride

The cold hydroxylamine leach has been used extensively by exploration geologists because it is selective for manganese oxides, long known to be powerful scavengers of heavy metals of geochemical significance. Manganese forms several oxidation states and exists in a variety of amorphous and crystalline forms. As a result, manganese oxide has an extraordinarily high cation exchange capacity, accommodating many different trace elements on its surfaces. This leach does not dissolve crystalline iron oxides but does dissolve very small amounts of amorphous hydrous iron oxide.

hot hydroxylamine hydrochloride

The hot hydroxylamine leach, which combines a higher concentration of hydroxylamine with elevated temperature (60°C) and a reducing acid environment, is capable of effectively dissolving amorphous hydrous iron oxide while leaving crystalline iron oxide substantially intact (typically <1% dissolution). As amorphous hydrous iron oxide is a much more effective scavenger than crystalline forms of iron oxide, this leach can be quite informative about metal ion mobility.

Sodium Pyrophosphate

Organic matter in soils and sediments is capable of forming chelation complexes with metals. A solution of neutral (pH 7) sodium pyrophosphate liberates these organically-bound heavy metals. Variations in the concentrations of organically-bound metals such as copper, zinc, cobalt, nickel, iron and aluminium have been used as indications of buried mineral deposits. Extraction with pyrophosphate does not attack sulfides, nor does it dissolve significant amounts of amorphous iron oxides

Isotope geochemistry is useful to determine the source and age of geological materials. Improvements in instrument technology now allow the detection limits required to measure a variety of element isotopes, providing a deeper level of understanding of the composition of geological materials. Isotope determinations are increasingly documented to provide unique signatures that relate to specific styles of mineralization and alteration. Improved technology continues to increase the number of elements for which isotopic abundances may be measured.

isotopesIsotopic determinations are made using the Sector Field ICP-MS (ICP-SFMS), providing precision of 0.05% relative standard deviation. Even greater precision can be provided by the multi-collector ICP-MS in which simultaneous measurement of the isotopes is made by individual detectors. The MC-ICP-MS can measure precision to 0.001% relative standard deviation.

Analysis of mine concentrate and metallurgical samples is critical for the purchase and sale of commodities as well as the optimization of the recovery process. With so much riding on a correct result, control assays require meticulous work by highly trained technicians. The results must be of the highest calibre for reliability, accuracy and precision.

Concentrates, Metallurgical Materials and Bullion analysisWherever ALS Minerals performs work on commercial grade materials the facilities are carefully separated and dedicated for such work. ALS Minerals employ highly trained and experienced registered assayers to oversee the work. All such work is performed using classical techniques, analyzed in duplicate as a minimum to assure quality.

ALS Minerals will also perform umpire analyses in cases of buyer/seller dispute. Umpire work is conducted with the same degree of attention but is performed to an even higher degree of precision. In addition to concentrate work, our specialty assay facilities are available for the analysis of precious metal bullions and other metallurgical materials such as carbon from leach circuits.

Major Minor and Trace elements in Concentrates

ALS Minerals has multi-element procedures specifically designed for this application. If desired, an analysis of this type can be combined with automated mineralogy using our in-house Mineral Liberation Analyzer (MLA) for a full mineralogical characterization. Please keep in mind that matrix and concentrate elements may create interferences that may prevent some analytes from being available for reporting.

Industrial minerals are those whose commercial value does not rely on the production of a metal or fuel from the mineral source. Typical examples include limestone, clay, silica, gypsum and talc. Metallic compounds where used in non-metallic form such as rutile or titanium dioxide are also included in this group.

industrial mineralsIndustrial mineral analysis commonly includes analyses that deal with unusual matrices and highly refractory components. As a result, aggressive digestions are selected to ensure complete homogeneity of the analytical sub-sample leaving no residual sample.

We have extensive experience analyzing industrial mineral products such as phosphates, beach sands, ilmenites, raw building materials such as limestone and dolomite right through to intermediate processing plant flows and product streams. Typically these analyses are used to characterize the commercial material, identify contaminants and quality variations, and to provide legislative checks for waste acceptance and occupational hygiene purposes.

The procedures listed below are designed to provide optimum results for each material type or product. This includes the specific digestion procedure, calibration protocols and the use of appropriate Certified Reference Materials for each sample type. Where a more inclusive element suite or lower detections limits are required, ALS Minerals can customize methods or develop new procedures to suit individual needs.

applied Mineralogy with LithogeochemistryExploration success can be significantly enhanced by combining state of the art Mineralogical analysis (using Mineral Liberation Analyzers – MLA) with comprehensive, low detection multi-element geochemistry (using ICP-MS, ICP-AES and XRF instruments). ALS Minerals now offers competitively priced packages which provide both percentage mineral abundance and quantitative elemental distributions as Applied Mineralogy-Geochemistry packages. These comprehensive analysis packages are ideally suited for regional rock chip sampling programs and “bottom of hole/basement” samples from exploration drilling under deep cover.

In many instances geologists are forced to operate in new geographies with little logistical support and yet are still expected to collect data that is meaningful and insightful. To support such efforts, many ALS facilities now offer a variety of services to help collect and analyze drill samples in a highly-secure and controlled environment. Together these services can provide a streamlined and easy way to collect, store, and retrieve a wealth of information very soon after core is provided to the laboratory.

Core Cutting and Other ServicesIn the past year, ALS Minerals has introduced a group of services called the “ALS Core Shed” in which we provide services to help you manage your core samples in the field with greater ease and less expense. ALS Core Shed services can be bundled in any combination and cover the full range of handling and management that clients are typically engaged in at a remote drill site.

Clients who ship core directly to the nearest ALS facility will find a comfortable, dedicated, secure and safe space in which to lay-out and log core, lighting and infrastructure to support core photography, equipment to scan core using portable x-ray equipment and in selected locations, equipment to provide infra-red and hyperspectral scans for mineralogical information prior to chemical analysis. As with all our services, all information can be readily uploaded to our Webtreive™ system for easy distribution and access from anywhere in the world.

ALS Core Shed services include:

• Secure and dedicated rental space for layout and logging of core or other materials

• Core cutting services

• High resolution core photography linked to Webtreive™ for online viewing

• Hand-held portable XRF equipment and analysis for quick point determinations

• Specific gravity and/or bulk density testing

• Secure, barcoded on-site storage that can be seen and monitored via Webtrieve™

• Complete sample preparation and multi-element analysis of core samples as required

ALS Minerals now offers a ground-breaking and unique core photography service. This service allows high quality photographic images of core to be collected on our web-based service for secure sharing and ready pairing with analytical data to aid geological interpretation and communication without return to the core box.

Virtual Down-hole Core PhotographsOur exclusive image processing software allows ALS Minerals locations to offer a unique, high quality core photography service that will help enhance geologic interpretation, as well as the communication of findings within your company.

High quality, parallax corrected photos of core in normal core boxes are rendered into continuous down-hole images that allow close-in zoom capability to aid identification of micro geologic features, as well as appreciation for the larger-scale elements of lithology and structure. Our process uses an automated image registration that combines each row of core in a series of core boxes into one continuous visual image.

At a client’s request, this photographic information can be combined with security-encrypted down-hole depth registration that allows geochemical information to be viewed graphically in conjunction with the actual core images. Down-hole depth information is securely encrypted such that it is only viewable by the client and not accessible by unauthorized users, or even ALS Minerals personnel. Best of all, this information can be retrieved or shared with other authorized users anywhere and anytime around the globe using Webtreive™.

This new service aids the interpretation and understanding of geology and the geochemical characteristics of a project and allows the cataloguing and secure archiving of data related to drill holes.

Our service includes:

• Exclusive software to acquire high resolution, parallax corrected core images

• Image processing to produce “strip-log” style, continuous down-hole display of core

• Down-hole depth registration

• Image zoom capability

• Easy image archiving and retrieval

• Simplified geologic and geochemical interpretation

Truly remote projects require a higher degree of support. Each project has particular demands and no two circumstances are exactly alike. The logistics and expense of sample shipment often drives a need for carefully designed on-site sample preparation. In some situations, on-site analytical capability is required.

Custom Mobile Sample Preparation FacilitiesALS Minerals offers clients a MOBILE PREPARATION LAB option for setting up on-site facilities. Mobile preparation labs have been manufactured for years exclusively by ALS Minerals for ALS clients. We have many in operation at any time around the globe. We have two standard sample preparation configurations and we have extensive experience manufacturing more customized solutions for clients whose requirements are more demanding.

A mobile sample preparation module consists of either a 10 by 20 foot, or a 10 by 40 foot standard shipping container, which is converted into a sample preparation area housing:

• one/two heavy duty crushers

• one/two large bowl ring pulverizers (2 kg capacity bowls)

• working stations

• dust collector

• electric drying oven including carts

• heavy duty air-compressor

• a nominal diesel powered generator package 100 kVA (optional)

Complete labs can be manufactured in 6 to 8 weeks.

ALS On-site Support

An ALS Minerals supervisor will be on-site for the installation of the facility. ALS Minerals can also be contracted to provide on-site training in most languages (English, French, Spanish, Russian and others). You can also have one or more of your staff trained at an ALS Minerals facility. Under certain conditions and given enough lead time, ALS Minerals is also able to operate such facilities on a contract basis.
