Mr. Adolfo ZambranoBiotrol, Ino.11 ?eavey RoadChaska, MN 55318

Dear Adolfo:

Please find enclosed a preliminary report of analysis for the 9samples received on 10/26/89. A final report will be issued uponcompletion of the TOC analysis.

The total arsenic was analyzed by Methods SW 3050 and SW 7060(attached). Upon receipt of your procedure, two samples werereanalyzed using the sulfuric-nitric-persulfate digestion. Theresults are as follows:

Sample Run #1 Run $289-23D 960 945 mg/kg As89-28E 113 105 mg/kg As

The results were in close agreement (7 and 2"s), therefore theother samples were not reanalyzed. The sulfuric-nitric-persulfate digestion will be used on all future samples. Pisasaverify whether or net Method SW 7060 is acceptable. Also, is theenclosed analytical and quality control date adequate?

Sample 89-29, unpreserved, was analyzed "as-is". The differencein TOC results for sample 89-29 (unpreserved 65 mg/L andpreserved 1.1 mg/L) represents the inorganic carbonates in thesample. Samples that are to be analyzed for TOC should bepreserved with H2SO4 to pH -'2. All metals should be preservedwith HN03 to pH

Several alkaline phosphates, particularly tetrasodium pyrophos-phate and trisodium phosphate, are used as dispersants in theflotation of slimy ores, especially for those ores containing iron oxide

, slimes.

Because of the sequestering properties of these compounds they areuseful in reducing the harmful effect of heavy metal ions in solution.

CYQUEST 3223 Antiprecipitant =CYQUEST 3223 is an acrylic polymer. It is not a sequestering orchelatinpaftentin the true chemical sense as its action in suppressingnucleation is more physical than chemical. Because of this action, itreduces the harmful effect of soluble salts in flotation.

CYQUEST 3223 also has applications in fields other than mining.These are described in a separate publication.*

CYQUEST 3223 Antiprecipitant is readily soluble in water at roomtemperature. It can be prepared in solution form at concentrationsup to 25% by weight, and can be diluted from this strength asnecessary for accurate feeding.

Typical Physical PropertiesTexture: Free flowing powderSolubility: 25% solubility in waterAlkalinity, 1% solution: pH 10.8Viscosity, 1% solution: 1.5 cps.

CYQUEST 3223 is somewhat hygroscopic and will absorb moistureon exposure to a humid atmosphere. It should be stored in tightlyclosed containers.

1.0 ARSENIC PARTITION STUDY I

This phasa of the study on contaminated soil samples from the iWhitmoyer Laboratories Site will attempt to establish the degree -̂"|of solubility of arsenic species in background groundwater from the |site at room temperature (25 ± 1'C) .

1.1 Pretreatment I

The materials received from the Whitmoyer Laboratories Siteare the soil samples and the background groundwater sample. The Idifferent soil samples came with varied degrees of moisture, Iranging from 12 to 27%. In order to allow for meaningfulcomparisons, the following normalization will be carried out: i

1.1.1 Soil Samples

a) Each sample will be air dried at room temperature Ito constant weight. I

b) The dried agglomerated soil will be gently brokenup using mortar and pestle and rocks and extraneous ldebris will be removed and discarded. |

c) No additional size reduction is recommended in orderto preserve the natural size distribution of the *soil as intact as possible. I

1.1.2 Background Groundwater

The entire 25 gallons of groundwater will be filtered ^J\using Whatman No. 5 paper filter to remove soil particlesgreater than 3 microns. i

1.2 Experimental Design

There will be five different soil samples to be evaluated for Iarsenic partitioning. Each soil sample will be evaluated according *to the experimental design given in Table 1, which will evaluatethe effects of four (4) water/soil weight ratios and six (6) water Ilixiviation times. 1

1.2.1 Experimental Procedure •The experiments will be conducted using two Lab-Line I

mechanical mixing tables capable of holding 24 erlenmeyerseach. The tables will be operated to impart a rotationalspeed of 180 RPM to each individual 1000-ml flask. 1

A sample of 500 ml background groundwater will betransferred to each 1000-ml erlenmeyer flask. A weight of Isoil corresponding to the desired water/soil ratio will be |weighed to the nearest 0.1 gram, as shown in Table 1, andadded to the flask. The flask will then be sealed with a Ineoprene rubber stopper. Each flask will be identified with Ian unique test number as follows:

1.0 ARSENIC REMOVAL

2.0 EXPERIMENTAL DESIGN

I

IThis Phase-I effort will be concentrated on the utilization of

physico-chemical means to remove the leachable fraction of the Iarsenic present in the soil at the Whitmoyer Laboratory site. I

1.1 Materials I

Two different soil samples will be tested in this phase of theoverall study. Sample No. WL-TS-207-06 containing 4,000 mg/Kg .arsenic represents the worst case, while sample No. WL-TS-208-99 Icontaining 850 mg/Kg arsenic represents a composite average of the *site.

All arsenic-removal tests will be conducted using the Ibackground groundwater sample No. WL-MW-105-A, which analyses 3 ppbarsenic, as the suspending medium. I

1.2 Arsenic Extractanta

The reagents to be used for the extraction of arsenic will be IHC1, HNO,, H2SO4, Na2SO,, NajS-O,, NaOH, Na2CO,, Xanthate Z-5, cyquest \̂ SDP-3 & DP-6, NaHS, sodium EtfTA, Ethanol ana other minor additives.The experiments to be conducted will consider single and combined Ireagents for the arsenic removal approaches implemented in this Iscreening phase.

\

The scheme for arsenic removal will consist of twelve >4T-hour .single stage leaching tests performed using the composite soil >j _> Isample. All tests will be conducted at room temperature using J5&~ 'grams of air-dried soil slurried to a 35% pulp density. Anydeparture from the 24-hour testing will be detailed in the 1experimental procedure section. J

2 . 1 Experimental Procedures •

2.1.1 CASE A: HC1 Leach.

This extraction approach will consist of leaching in a I35% slurry maintained at pH-1.0 with HC1. A leaching time of I24 hours under constant agitation by a magnetic stirrer willdefine the treatment. 1

SR300596

After filtration, solid and liquid.phases will besubmitted for determination of pertinent parameters.2.1.2 CASE B: H-S04 Leach.

A slurry at 35% solid will be leached for 24 hoursmaintaining pH - 1.0 throughout the test. Both solids andsolution will be analyzed for pertinent parameters.

2.1.3 CASE C: HN03 Leach.

This leaching approach will evaluate the performance ofHN03 under the same conditions as Case A. Because of theoxidizing nature of nitric acid, arsenic fixation may takeplace depending upon the available level of ferric iron in thesystem.

2.1.4 CASE D: NaOH Leach.This leaching approach will investigate the lixiviating

power of NaOH at pH - 11. This lixiviant is more selectivethan the acids but may require a temperature optimizationscheme if it shows promise at room temperature.

2.1.5 CASE E: Na2C03 Leach.

This approach is a comparison with Case D for the removalof trivalent arsenic. Leaching conditions will be identical atpH - 11, pulp density at 35% solids and 24 hours leachingtime.

2.1.6 CASE F: KC1 + Na2S03 Leach.

The attempt with this approach is to promote thesolubilization of trivalent arsenic by reducing with thesulfite ions at pH » 1 and at a level of 20#/ston of solids.

2.1.7 CASE G: HC1 + Na2S2O3 Leach.

This is a comparison with Case F for the reducing powerof two different sulfur compounds under identical acidicconditions. A critical difference however is the complexingeffect of the thiosulfate which has the tendency to promotehigher solubilizations. A level of 20f/ston of solids will betested.

2.1.8 CASE H: HC1 + Cyquest DP-3 Leach.

Case K is a comparison to Case A for acid leaching at pHequal 1 but trying to prevent any arsenic fixation by theaddition of DP-3 at ll/ston of solids.

This is a comparison with Case E for carbonate leaching Iat pH • 11, but trying to prevent arsenic fixation by theaddition of DP-6 at l#/ston of solids. i

2.1.12 CASE L: HC1 Leach + Flotation.

This is a combination approach attempting to maximize Iarsenic removal. The leaching part of this test will be \*-̂ 'conducted at pH - 1 for 3 hours only. After filtration, thefilter cake will be re-slurried to 35% solids with a HC1 Isolution of pH - 6 and conditioned for 5 minutes with the |following levels of reagents per ton of solids:

2.2 Sample Identification ;

Each test will generate two samples: the leach filtrateand the leached solids. The leached solids are obtained afterthree washing stages at pH - 5 or pH » 7 for acid and basicleaching tests respectively. These test products will beidentified by a general test number of the form:

R-pH-St-State,

whereR - Reagent(s) namepH - pK value at which the test was controlledS# - Sample number of soil sample from Whitmoyer siteState - A letter for Leachate(L), Solid(S), or Filtrate(F).

The only test generating three samples will be Case L, whichcombines two processing steps: leaching and flotation.

The final Leachates or Filtrates submitted for analysiswill be the composites of original aqueous products plus washwater.

2.3 Leaching Procedures Selection

From the results of the twelve screening test, the best fourleaching approaches will be chosen to conduct four leaching testsusing the Whitmoyer soil sample No. WL-TS-207-06 which representsthe worst case. After completion of these four leaching tests, thetwo best approaches will be implemented in the Phase II of thisstudy.

3.0 CHEMICAL ANALYSES AND PROCEDURES

The filtrates from the twelve leaching tests performed oncomposite sample No. WL-TS-208-99 as well as the four filtratesfrom the worst soil sample No. WL-TS-207-06 will be analyzed fortotal arsenic, TOC, and TS.

The leached solids obtained according to the best fourleaching approaches applied to these two soil samples will beanalyzed for the following parameters:

- Total arsenic level,- TCLP Leachate Procedure: Total arsenic,- ASTM Leachate Procedure: Total arsenic, TOC, TDS, and pK*These same parameters will also be determined by themodified ASTM procedure using upgradient groundwater as thelixiviant.

1.0 ARSENIC REMOVAL OPTIMIZATION I

Based on the sixteen leaching cases completed in Phase I ofthis study, the best two approaches will ba implemented to simulate Ia four-stage leaching extraction train for arsenic removal from the |two soil samples tested during the exploratory Phase I.

1.1 Materials I

The two different soils to be tested during this Phase-IIeffort will be the average composite and the worst case samples. 1The worst case sample is identified as Sample No. WL-TS-207-06 iwhich has an average arsenic content of 4,000 ppm, while theaverage composite corresponds to Sample No. WL-TS-208-99 having an iarsenic content of 850 ppm. j

The implementation of the arsenic removal schemes will be .carried out using the background groundwater sample identified as Isample No. WL-MW-105-A which analyses 3 ppb arsenic. ~^S '

1.2 Arsenic Extractanta I

The best two leaching schemes in Phase I were Case M and Case0 , which correspond to the following approaches: i

Case M: Na2CO3 + Na_S203Three hundred grams of soil are leached with sodium .

carbonate at pH - 11 for 4 hours in the presence of sodium Ithiosulfate at a level of 20 Ib/ston of solids. The leaching 'is performed at room temperature while necessary pHadjustments are made with a NaOH solution of known strength. 1

Case 0: Na,CO3 + DP-6.This test is conducted like Case M, except that DP-6 is .

used instead of the thiosulfate at a level of 1 Ib/ston of solids. I

At the end of the leaching period, the slurry is filtered andthe filter cake is washed three times with groundwater adjusted to IpH - 7.5 with NaOH. J

Because the lixiviants in these two leaching approaches aremore than 50 times the amount of contained arsenic in the leachfeed, the concentration of the reagents is in excess of thestoichiometric requirements. Therefore, reaction time is one ofthe pertinent operating parameters that can be investigated tooptimize arsenic removal. v

A four-stage simulation could provide .pertinent kinetics forproper sizing of the site remediation plant. This simulation canbe implemented through crosscurrent leaching of coil samples for aholding time of four hours per stage. The required four tests willbe conducted according to the leaching scheme shown in Figure 1.

Each test will be conducted at room temperature using 300grams of dried" soil slurried to 35% solids with backgroundgroundwater, except for test No. 4 which will be conducted usingeither 1,200 grams of soil, or 600 grams in triplicate tests inorder to prepare the samples for Ebasco. Mechanical stirrers willbe used at the necessary speed to maintain the solids insuspension. ,:; • < •

i ; 2.1 Experimental Procedures

The leaching approaches will be as described in section 1.2and according to the crosscurrent scheme of Figure 1.

The slurries from every leaching stage will be flocculatedusing Allied Colloids' Percol E10 at a dosage of 0.5 Ib/ston ofsolids prior to filtration. This dosage will vary depending onslurry's degree of dispersion.

2.2 Sample Identification

Each test will generate the leached solids residue and theleach filtrate composite. The leach composite will be the combinedvolume of the slurry filtrate plus the washwater volume to wash thefilter cake three times by displacement. This volume will be equalto the original volume required to make the original slurry. ThepH of the washwater will be 5 for an acid leach and 7 for a basicleach. The identification of the test products will be accordingto a test number of the form:
