Executive Summary

SGS was contracted by Nussir AFA (Nussir) to complete environmental characterisation of tailings and

process waters generated from ore from the Kvalasund deposit located in Norway. The purpose of the

environmental test program was to assess the geochemical and toxicity potential associated with marine

disposal of the tailings material (F12 Comb Tls).

Rietveld x-ray diffraction (XRD) analyses determined that the F12 Comb Tls sample was predominantly

comprised of silicates and carbonates (largely in the form of calcite). Results of the whole rock and

elemental analyses confirmed the primarily silicate composition of the tailings sample. Significant levels

of Ca and Al and minor to trace amounts of K, Fe, Mg and Na were also observed. The very high loss on

ignition (LOI) value reported suggests the presence of large amounts of volatile species (e.g. hydrates,

hydroxides and carbonates).

Modified acid base accounting (ABA) test results suggested that the F12 Comb Tls sample is potentially

acid consuming. The non-acid forming nature of this sample was corroborated by the NAG test results which

reported no net acidity generated after aggressive oxidation of the sample.

Analysis of the synthetic precipitation leaching procedure (SPLP) leachates and the EN 12457-3

extraction test leachates reported all World Bank controlled parameters, with the exception of pH in the

SPLP sample, at concentrations well within the specified limits. Although significantly higher metal

concentrations were typically reported in the modified SPLP and modified EN 12457-3 extractions (using

the artificial seawater as the leachant); it would appear that only very low levels of metals were released

into solution as the concentrations of most parameters did not increase largely from that reported for the

seawater blanks.

Sediment toxicity testing of the F12 Comb Tls solids using marine polychaete worms (Polydora Cornuta)

reported a 50% reduction in the growth of the test organisms. While the tailings sample failed the 10 day

marine amphipod test (Eohausorius Estuarius) with a 55% mortality rate, the F12 Comb Tls passed the

solid phase microtox assay completed on the Vibrio Fisheri bacterium.

Analysis of the F12 Comb Tls Decant (process water) and fresh and aged F12 Comb Tls Salt Water

Decant solutions (artificial seawater) reported all World Bank controlled parameters at concentrations

within the designated limits. Increasing levels of Cl, As, B, Ca, Mn, Mo, Se, Si, Sr and U and decreasing

levels of Al, Ba, Cd, Th and Ti were generally evident over the 56 day ageing test period.

Results of the particle size distribution analyses indicated that the F12 Comb Tls sample tested was

comprised primarily of fines with 78% of the sample passed the 200 mesh (0.075 mm) sieve.

Sample Descriptions and Test Methods

The following sections provide brief overviews of the samples received and the test methods included in

the environmental characterisation program.

1. Sample Descriptions

A single combined flotation tailings pulp sample (F12 Comb Tls) was received from metallurgical

department. The F12 tailings tested, which were determined to be identical to the locked cycle test

tailings (LCT-1) from the flotation test program (SGS project reference 12527-001), were considered to be

the most representative of plant response in a laboratory environment. The artificial seawater used in the

test program was generated by blending 493 g of Instant Ocean® with 17 L of deionised water.

2. Sample Preparation

Upon receipt, the tailings pulp sample was allowed to settle overnight prior to the decantation of a

process water sample for analysis. The pulp sample was then mixed for 60 minutes at 200 rpm to ensure

all solids were thoroughly recombined prior to the extraction and filtration of the solids on No. 1 Whatman

filter papers. Representative portions of the resultant filter cake solids were prepared for the proposed

geochemical and geotechnical testwork and analyses according to SGS Standard Operating Procedures

and the individual test method protocols. The solids subjected to sediment toxicity testing were blended

with a sufficient volume of artificial seawater to facilitate this testwork. The remainder of the filter cake

solids were subsequently blended (60 minutes at 200 rpm) with a volume of saltwater identical to the

volume of process water removed during the liquid solid separation (filtration) thereby generating a slurry

of tailings and seawater that maintained the original ratio of liquids to solids of the initial pulp sample.

While the seawater tailings slurry continued mixing, individual Day 0, 7, 14, 28 and 56 ageing test

charges were extracted. The fresh Day 0 tailings sample was allowed to settle undisturbed for 2 hours

prior to the supernatant being decanted and submitted for analyses.

3. Test Methods

The following sections provide a brief overview of the test methods included in the environmental

characterisation program.

3.1. Rietveld X-ray Diffraction Analyses

A representative portion of the sample was submitted for Rietveld XRD analyses in order to identify the

bulk mineralogy, crystalline assemblages and the relative proportions of the mineral phases (as wt.%). In

this method, x-rays are used to bombard a powdered sample. The x-rays, which penetrate a very thin



3

layer of the sample, are diffracted by lattice planes of minerals. These unique diffraction patterns were

used to semi-quantitatively identify the minerals contained within the sample. These analyses were

subcontracted to the Department of Earth and Ocean Sciences at the University of British Columbia.

3.2. X-ray Fluorescence Whole Rock Analyses

Whole rock analyses were completed on the sample using a quantitative XRF method in order to

determine the elemental concentrations of the major rock forming constituents. This method quantifies

major elements present and reports them as oxides to permit a mass balance assessment against the

component of a sample that is amenable to oxidization (loss on ignition).

3.3. ICP-OES/MS Strong Acid Digest Elemental Analyses

The samples were digested using an acid mixture of HNO3, HF, HClO4, and HCl to obtain a near total

digest of the parameters being analyzed. ICP-OES/MS trace metal scans were performed to provide

quantitative analyses of the elemental components of the sample material. Analyses requested included:

Ag, Al, As, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Se, Si, Sn, Sr,

Ti, Th, Tl, U, V, W, Y, Zn and Zr. Mercury analyses were completed by cold vapour atomic absorption

spectroscopy (CVAAS).

3.4. Modified Acid Base Accounting

The modified ABA test provided quantification of the total sulphur, sulphide sulphur, and sulphate

concentrations present and the potential acid generation (AP) related to the oxidation of the sulphide

sulphur concentration. The test method determined the neutralisation potential (NP) of the sample by

initiating a reaction with excess acid and then identified the quantity of acid neutralized by the samples

NP by back-titrating to pH 8.3 with NaOH. The balance between the AP and NP assists in defining the

potential of the sample to generate acid drainage. In addition, quantification of the extent of carbonate

mineral content permitted calculation of the theoretical carbonate NP.

3.5. Net Acid Generation Testing

NAG testing was conducted to determine the balance between the acid consuming and acid producing

components of the tailings. The NAG test initiated a reaction between the sample and concentrated

hydrogen peroxide in order to force complete oxidation and reaction of the acidity produced with the

neutralising minerals present within the sample. After the reaction ceased, the pH of the solution was

measured (NAG pH). The acid remaining after the reaction was titrated with standardized NaOH to pH

4.5 and the net acid generated by the reaction was calculated and expressed in units of kg H2SO4

equivalent per tonne. The NAG4.5 value is indicative of the contribution from free acid, Al and Fe.

Titration from pH 4.5 to pH 7.0 can provide additional information for sample characterisation as, under



4

certain conditions, the NAG7.0 is indicative of the presence of metallic ions that consume alkalinity over

this pH range, such as Cu and Zn.

3.6. Synthetic Precipitation Leaching Procedure

The major objective of the SPLP extraction is to determine the leachability of metals from solid samples

under acidic conditions such as those created by ARD or acid rain. For the Nussir sample, the SPLP

leachant was adjusted to a pH of 4.2 ± 0.05 (extraction fluid No. 1) through the addition of a 60:40 weight

percent mix of sulphuric and nitric acid to DI. The leachant was combined with the sample in a 20:1 ratio

and the sample container was rotated end over end for 18 hours. The resultant slurry was then filtered

through a 0.7 µm glass fibre filter and the leachate analysed for total metals based on the previously

noted suite of parameters. A modified SPLP test was also completed on the tailings following the same

protocol as noted above but using artificial seawater as the leachant.

3.7. EN 12457-3 Extraction Testing

The European standard EN 12457-3 extraction test is based on the assumption that equilibrium or near-

equilibrium is achieved between the liquid and solid phases under the pH conditions imposed by the

waste itself during the test duration. This two-stage deionised water batch extraction test, typically used

for materials with a high solid content and with a particle size below 4 mm, is completed at liquid to solid

ratios of 2 L/kg and 8 L/kg. The tailings were also subjected to a modified EN 12457-3 extraction using

artificial seawater.

After completion of the first (2 L/kg) liquid to solid extraction (6 hours), the liquid phase was separated

from the solids by filtering through a 0.45 μm membrane filter. The liquid phase was subsequently

submitted for ICP-OES/MS analyses while the residual solids were re-eluted at the higher liquid to solids

ratio (8 L/kg) and extracted for a period of 18 hours. The solids were again separated from the liquid

fraction and the resultant liquid was submitted for analysis.

3.8. Survival and Growth Testing of Spionid Polychaete Worms (Polydora Cornuta)

Survival and growth testing was completed to evaluate the effects of exposure to the tailings solids on the

reproduction of the marine polychaete worm (Polydora Cormuta). As per the Environment Canada EPS

1/RM/41 test method, each treatment consisted of 5 replicates utilising five organisms per replicate over a

14 day period.

The tests were conducted in 300 mL glass vessels containing 50 mL of sediment with approximately 200

mL of dilution water (reconstituted sea water at 30±2 g/kg salinity) and aerated overnight. After 24 hours,

5 polychaetes were randomly introduced to each test vessel. The test was conducted at 23±1°C with

overhead fluorescent illumination of 16 hours light (providing between 500 and 1000 lux intensity at the



5

sediment surface) and 8 hours dark. After 14 days the vessels were poured through stainless steel

screens and the surviving organisms are retrieved, counted and weighed. Each test is accompanied by a

control test containing reference sediment. The biological endpoint for the test is percent survival and

growth at Day 14. All toxicity tests were subcontracted to Aquatox Testing and Consulting Inc (Aquatox).

The total organic carbon, moisture content (dry weight basis) and particle size distribution (determined by

sieve and hydrometer) of the test sample was determined by SGS and supplied to Aquatox for the

completion of this testwork.

3.8.1. Total Organic Carbon

A weighed sample of the tailings sent for sediment toxicity testing was fully oxidized by combustion in an

oxygen atmosphere and the CO2 gases evolved were detected by calibrated infra-red (IR) cells. Total

carbon (C) content was measured as mg and calculated as a percentage of the sample weight.

3.8.2. Moisture Content

The moisture content of the tailings sample for sediment toxicity testing was determined by drying 3

representative cuts of the sample at 60°C until they reached a constant weight and averaging the results.

It should be noted that the moisture contents were calculated based on a dry weight basis as per the

equation below.

MC = Weight of Water/Weight of Dry Solids

3.8.3. Particle Size Distribution

The tailings submitted for sediment toxicity testing were analysed for particle size using the sieve and

hydrometer test methods (a description of the particle size test method is provided in Section 3.12).

3.9. Amphipod Acute Survival Testing Using Whole Sediment

The 10 day marine amphipod test indicates the adverse effects of contaminated sediment on marine

organisms. This test followed the EPS 1/RM/35 and EPS 1/RM/26 test method protocols from

Environment Canada with each treatment consisting of 5 replicates using 20 organisms (Eohaustoriu

Estuarius) per replicate over a 10 day period.

The tests were conducted in 1 L glass vessels containing 175 ml of sediment and 950 ml of dilution water

(reconstituted sea water at 30±2 g/kg salinity) and aerated overnight. After 24 hours, 20 amphipods were

randomly introduced to each vessel. The test is conducted at 15±1°C with constant overhead fluorescent

illumination between 500 to 1000 lux intensity at the sediment surface. Each test is accompanied by



6

control containing reference sediment collected from the same area as the test organisms. After 10 days,

the vessels are poured through stainless steel screens and the surviving organisms are retrieved and

counted. The biological endpoint for the test is percent survival at Day 10.

3.10. Solid Phase Mircrotox Testing

This test method (EPS 1/RM/24) exposed luminescent bacterium to the sediment sample. Toxic

materials present interfere with the cellular respiration of the organism, which is measured as a decrease

in light output by the bacterium, Vibrio fischeri (previously Photobacterium phosphoreum).

An aliquot (7 ± 0.05 grams) of the wet sediment was transferred to a beaker and stirred for 10 minutes

with 35 mL of solid phase diluent. A dilution series of 12 concentrations and 3 controls were prepared

from this mixture. Bacterial reagent was added to the dilutions and incubated at 15°C for 20 minutes.

These dilutions are filtered to remove sediment particles and the filtrate transferred to cuvettes in the

Microtox analyser. After 10 minutes in the analyser bioluminescence is recorded. The EC50 was then

calculated on a wet weight basis (the concentration of test sediment at which light output by a population

of the luminescent bacterium is reduced by 50% when compared to the untreated control population).

Three aliquots of the sediment were dried and the percentage moisture determined. The IC50 (inhibiting

concentration to 50% of the population) was corrected for moisture content and quoted on a dry weight

basis as mg dry sediment/L of diluent.

3.11. Analysis of the Fresh and Aged Tailings Decant Solutions

Liquid analyses were completed on the initial tailings decant solution (process water) to provide

quantitative analysis of the elemental components and to aid in the identification of elements present at

potential environmentally significant concentrations.

The fresh and aged seawater solutions were decanted from the settled tailings slurries and analyzed after

defined periods of ageing. The objective of this testing was to identify changes in the seawater solution

that had been blended with the tailings over time, and quantify elemental concentrations that may be

released. Decant solutions were collected and submitted for chemical analysis of the following

parameters: pH, alkalinity, acidity, conductivity, EMF, TSS, TDS, anions (Cl, F, SO4, NO2 and NO3), total

thiosalts and ammonia (NH3 and NH4). Total metal analyses were completed as per the previously noted

suite if parameters.

3.12. Particle Size Distribution Analyses (ASTM D 422-63 (2007))

The Micromeritics Model 1305 multivolume gas pycnometer measures the volume of powdery, granular,

porous and irregularly shaped solids in the solids using Boyle’s Law. The test used a known weight of

solids to quantitatively determine the specific gravity of the solids.



7

Standard screen sieve sizes (Tyler) were used to determine the particle sizes of the solid tailings

particles. The weights of the percent retained and passing on each respective screen size were

determined. The test determined the particle size distribution of the plus 200 mesh fraction of the product

being investigated.

The particle size distribution for the minus 200 mesh fraction of the tailings was established using the

hydrometer (sedimentation) method. A 50 g (dry equivalent) sample was placed into solution (dispersing

agent) with 1 L of distilled water in a standardized glass cylinder. The solution was agitated, and the

particles were permitted to settle out of suspension. As settling occurred over time, the average specific

gravity of the mixture decreased, causing the height of the suspended hydrometer to drop. Reading of

the hydrometer at specific time intervals provided (though established relationships) the weight of the soil

remaining in suspension, and the size of the particles that had settled out of solution. The percent finer

weight was calculated based on the hydrometer readings, using Stokes Law for spheres falling freely in a

fluid of known properties.

Discussion

Rietveld XRD analyses determined that the F12 Comb Tls sample was predominantly comprised of

silicates (68.5 wt.%) and carbonates (30.3 wt.%). Quartz was the dominant silicate mineral followed by

muscovite and plagioclase. Carbonates were largely in the form of calcite (28.4 wt.%) with minor

amounts of dolomite (1.9 wt.%) also being observed. Results of the Rietveld XRD analyses are illustrated

graphically in Figure 1 below.

Figure 1: Rietveld XRD Results

Results of the whole rock analyses confirmed the primarily silicate composition of the F12 Comb Tls

(48.9%). Significant levels of CaO (16.5%) and Al2O3 (9.4%) and minor to trace amounts of K2O (3.5%),

Fe2O3 (2.4%), MgO (2.3%) and Na2O (1.6%) were also observed. The very high loss on ignition (LOI)

value (13.8%) reported suggests the presence of large amounts of volatile species (e.g. hydrates,

hydroxides and carbonates). Figure 2 illustrates the results of the whole rock analyses.

ICP-OES/MS strong acid digest elemental analyses also corroborated the primarily silicate composition

(23.9%) of the F12 Comb Tls. As expected, moderate levels of Ca (10%) and Al (5.4%), minor levels of K

(2.9%) and trace levels of Fe, Mg and Na (< 2%) were observed. Comparative results of the elemental

analyses are presented in Figure 3. The significant components of the sample are illustrated in Figure 4.

Figure 4: Comparison of the ICP Elemental Significant Components

ABA test results for the F12 Comb Tls reported an alkaline paste pH value (9.38) and fizz rate (4)

suggesting the presence of significant amounts of available reactive alkaline minerals. Determination of

the carbonate (CO3) content of the sample also indicated that 99% of the total NP reported for the

F12 Comb Tls sample is related to fast reacting carbonate minerals. The resultant CO3 NP value (307

t CaCO3/1000 t), coupled with the very low sulphide content (<0.01%), clearly illustrate the neutralisation

capacity of this sample and indicate the potential for acid consumption. The non-acid forming nature of

the F12 Comb Tls was corroborated by the NAG test results which reported no net acidity generated and

alkaline final pH value (11.12) after aggressive oxidation of the sample

The SPLP is used to determine the mobility of contaminants due to interaction with slightly acidic

solutions, such as acid rain or acidic effluent. Since the pH of the SPLP leachant added was 4.2, the



19

alkaline pH value (9.07) reported is indicative of the inherent buffering capacity within the sample upon

initial exposure to acidic conditions. Analysis of the SPLP leachates reported all World Bank controlled

parameters, with the exception of pH in the sample using SPLP extraction fluid #1, at concentrations well

within the specified limits. It should; however, be noted that analysis of the SPLP artificial seawater blank

reported Cu and Ni concentrations in excess of the published concentrations for this commercially

prepared synthetic sea salt product (Instant Ocean®).

Overall, significant levels (> 1 mg/L) of B, Ca, K, Mg, Na, Si and Sr were observed in the leachates.

Significant increases (1 to 2 orders of magnitude) were observed in the concentrations of Al, As, Ca, K,

Mg, Mn, Mo, Ni, U and V released into the standard SPLP leachant (extraction fluid #1) in comparison to

the SPLP extraction blank. Although significantly higher metal concentrations were reported in the

seawater leachant in comparison to the SPLP leachant, it would appear that only very low levels of

metals were released into solution. Mn, Si and U were the only elemental components showing

noteworthy increases (1 to 2 orders of magnitude) in the modified SPLP leachate when compared to the

corresponding seawater blank. Decreased levels of Al, Ba and V were also observed in the modified

SPLP leachant in comparison to the standard SPLP leachant. Comparative results of the SPLP analyses

are shown in Figure 5.

Figure 5: Synthetic Precipitation Leaching Procedure Extraction Results

Liquid analyses results (mg/L) from the EN 12457-3 extraction tests reported all World Bank controlled

parameters within the specified limits. Increasing pH values were evident in the second extraction

(L/S=8) leachates from both samples tested. The Nussir samples (DI leachant and artificial seawater

leachant) generally reported significant concentrations of TDS, Cl, SO4, Ca, K, Na and Si. The salt water

extraction also reported considerable levels of B and Sr in solution. Although significantly higher metal

concentrations were typically reported in the EN 12457-3 extraction completed using the artificial



20

seawater as the leachant; again it would appear that only very low levels of metals were released into

solution as the concentrations of most parameters did not increase largely from that reported for the

seawater blank. Similarly to the SPLP extractions, the artificial seawater leachate showed noteworthy

increases in Mn and Si, and decreases in Al, Ba and V in comparison to the DI leachant. Increased

levels of SO4 were also observed in the 2nd seawater extraction leachate.

Results of the 12457-3 extraction leachate analyses were combined and re-calculated to give results on

the proportion of the constituents that are leachable (mg/kg) on a dry weight basis. Comparisons of the

liquid analyses from the blanks, first and second stage extractions and results of the calculated

cumulative amounts leached are provided in Figures 6 and 7.

Although the Polydora Cornuta (marine polychaete worm) sediment toxicity testing of the F12 Comb Tls

solids reported an 84% survival rate after 14 days, considerable impact was evident in the growth cycle of

the test organisms. A 50% reduction in growth of the Polydora Cornuta was statistically calculated upon

completing of the test.

The F12 Comb Tls failed the 10 day marine amphipod test (Eohausorius Estuarius) reporting a 55%

mortality rate. However, the F12 Comb Tls passed the solid phase microtox assay completed on the

Vibrio Fisheri bacterium.

Analysis of the F12 Comb Tls Decant (process water) and fresh and aged F12 Comb Tls Salt Water

Decant solutions (artificial seawater) reported all World Bank controlled parameters at concentrations

within the designated limits. The initial alkaline pH values (both process water and sea water) decreased

to near neutral (7.69) over the 56 day ageing test period. Moderate levels of alkalinity were maintained

and free acidity was not released. As expected, the addition of the artificial seawater to the tailings solids

resulted in immediate increases in the TDS, Cl and SO4 concentrations and in the resultant conductivity

measurements. Increasing levels of Cl, As, B, Ca, Mn, Mo, Se, Si, Sr and U and decreasing levels of Al,

Ba, Cd, Th and Ti were generally evident over the ageing test period. Comparative results of the

analyses completed on the fresh and aged decant solutions are shown in Figure 8.

Results of the particle size distribution analyses (sieve and hydrometer) indicated that the F12 Comb Tls

sample tested was comprised primarily of fines with only 22% of the particles falling into the fine sand

size category while 78% of the sample passed the 200 mesh (0.075 mm) sieve. The majority of these

fines were comprised of silt size particles (~72%) with only 6% of the particles falling into the clay sized

fraction.

EXPERIMENTAL METHOD

The sample “F12 Comb Tls” of Project 12527-002 was reduced to the optimum grain-size

range for quantitative X-ray analysis (<10 μm) by grinding under ethanol in a vibratory

McCrone Micronising Mill for 7 minutes. Step-scan X-ray powder-diffraction data were

collected over a range 3-80°2θ with CoKa radiation on a Bruker D8 Focus Bragg-Brentano

diffractometer equipped with an Fe monochromator foil, 0.6 mm (0.3°) divergence slit, incident-

and diffracted-beam Soller slits and a LynxEye detector. The long fine-focus Co X-ray tube was

operated at 35 kV and 40 mA, using a take-off angle of 6°.

RESULTS

The X-ray diffractogram was analyzed using the International Centre for Diffraction Database

PDF-4 and Search-Match software by Siemens (Bruker). X-ray powder-diffraction data of the

sample were refined with Rietveld program Topas 4.2 (Bruker AXS). The results of quantitative

phase analysis by Rietveld refinements are given in Table 1. These amounts represent the

relative amounts of crystalline phases normalized to 100%. The Rietveld refinement plot is

shown in Figure 1.
