Abstract
This report evaluates the leaching of oxoanions and other materials from mineral processing wastes, using the TCLP test as
well as several other alternative leaching tests (Generalized Acid Neutralization Capacity (GANG), Constant pH 5 0 Leaching Test
Constant pH Leaching Test at Various pHs, and Variable Mass Leaching Test).
Three actual mineral processing wastes were selected for evaluation. These wastes came from (1) fluvial tailings from the
Arkansas River, three miles from the mining district in Leadville, CO, (2) the Anaconda copper mine in Yerington, NV, and (3) from
a slag pile at a lead and zinc smelter near the village of Bearing, Montgomery County, in southeastern Kansas.
We found that mineral processing wastes vary widely in composition and characteristics. The three samples tested were soil-like
and varied in characteristics, with one being classified as a loamy sand, one a sandy loam, and the third a silty sand. Unfortunately, since
this study focused on leaching of oxoanions, none of the samples contained significant quantities of these materials The Yerington
NV sample was the highest, with 209 mg/kg As and 156 mg/kg Se. All three samples had TCLP leachate concentrations well below
the allowable limits, except for cadmium in the Dearing waste. The Leadville and Yerington wastes would be deemed suitable for
municipal landfill disposal, based on the TCLP test. The amount leached during the TCLP test varied from element to element and
from waste to waste, but variations were relatively minor. Less than 10 percent of most metals leached. For the oxoanions, very
little arsenic, cadmium or vanadium leached, while the amount of molybdenum and selenium leached varied from waste to waste.
However, the concentrations of these last two in the wastes were very low to begin with. Oxoanion leaching reached an equilibrium
fairly quickly, generally within one day. There was an immediate high degree of leaching, probably caused by surface washoff
followed by a constant arsenic concentration. Thus, the 18-24 hour leaching time used in the TCLP test is probably appropriate!
In general, the amounts of metals leached under the Constant pH 5.0 leaching test conditions and the TCLP leaching test are of the
same order of magnitude, although there is some variability between them. The concentrations of oxoanions leached under the two
leaching conditions are quite similar. Leaching tests run at several constant pH values between pH 3.0 and 9.0 were used to evaluate
the influence of pH on metal leaching. Results indicate that 24 hours of leaching is sufficient, and that many of the elements were
below detection limits at higher pH values. This is not surprising, because most metals have a lower solubility at pH values above
neutral compared with below neutral, although this may not be the case for metals in the anionic form. Most of the oxoanions were
also non-detectable, though, above pH 5.0.
Based on the results of this study, using this set of MPW wastes, it is concluded that the TCLP test is as adequate as any of the
other methods studied for estimating potential risk from the leaching of MPW wastes. The test procedure is simpler than other available
tests, and the results obtained from the TCLP test are comparable to those from other more demanding test procedures. The TCLP
test pH of 5.0 appears to be appropriate for MPW wastes, as is the 18-24 hour leaching period. It must be reiterated, though, that two
of the three wastes evaluated did not contain high levels of oxoanions, and the one that did exhibited a very low degree of leaching.
Other wastes might exhibit different leaching behaviors. It is recommended that use of the TCLP test for mineral processing wastes
be continued. A wider range of MPW wastes, that have been shown to leach oxoanions, should be evaluated, though.
This report was submitted by the University of Cincinnati (UC) in fulfillment of Contract No. 68-C7-0057 under the sponsorship
of the United States Environmental Protection Agency (EPA). This report covers a period from August 2000 through November
2001; laboratory work was completed as of August 2001.

1.0 Introduction
The purpose of this task order (Task Order No. 31, UC/EPA Contract No. 68-C7-0057) was to test several alternative leaching
tests — 1) Constant pH 5.0 Leaching Test, 2) Constant pH Leaching Test at Variable pHs, 3) the Generalized Acid Neutralization
Capacity (GANC) test and 4) the Variable Mass Leaching Test—against the Toxicity Characteristic Leaching Procedure (TCLP) test
for leaching from mineral processing wastes (MPW). This project was developed because of concerns relative to using the TCLP test
for solid wastes containing oxoanions (i.e., arsenate, chromate, selenate, vanadate). These elements, which are commonly present
in the anionic form in the environment, have acted acted differently under the TCLP conditions than do the cationic forms for which
the TCLP test was designed. Mineral processing wastes (MPW) often contain high levels of one or more of these oxoanions. Thus,
this project was developed to evaluate the leaching of metal oxoanions in mineral processing wastes under several test conditions.
The null hypothesis stated in the Quality Assurance Protection Plan (QAPP) for this project is: "There is no difference in
concentrations of oxoanions extracted by the control leach test (Toxicity Characteristic Leaching Procedure (TCLP)) and by the
alternative leach tests, (Generalized Acid Neutralization Capacity (GANC), Constant pH Leaching Test, and Variable Mass Leaching
Test), when used on mineral processing waste (MPW) for the measurement of leachability."
The primary objective of this project was to:
determine whether other leaching tests will give results different from the TCLP test when testing the leachability of
MPW.
Secondary objectives were to:
• determine whether other leaching tests are suitable for mineral processing wastes.
• characterize MPW.
The University of Cincinnati (UC) obtained MPW samples from three sites - Leadville, CO; Yerington, NV and Dearing, KS
- for testing and evaluation. The MPW samples were collected at the sites, transported to the UC laboratory, and tested using the
leach tests stated above. Special interest was focused on arsenic as it is an oxoion-forming element which has been reported to fail
the TCLP test for leachability.
-------
2.0 Background
Mineral Processing Waste (MPW) samples were collected from three different sites - Leadville, CO; Yerington, NV and Dearing,
KS.
2.1 Leadville, CO MPW
The first MPW samples were provided by Mr. Michael Holmes, USEPA. The samples were collected from fluvial tailings from
the Arkansas River, three miles from the mining district in Leadville, CO. They were reported to be high in metals (up to 5% lead
and 14% zinc) and to have greater than 300 ppm arsenic. The samples were shipped from Colorado Mountain College by Professor
Karmen Klima on November 10, 2000 and were received at UC on November 17,2000.
At the UC laboratory the samples were sub-sampled using a soil splitter. MPW samples were removed from the transportation
vessel and split repeatedly until representative samples of approximately 500 g were produced. A half-half splitter was used for
sub-sampling. The 75-pound sample was first split into two halves. Then each half was split into equal halves. By repeating this
process, sub-samples of approximately 500 g were produced and stored. The sub-samples were stored in glass jars with Teflon
liners. Sub-samples of a small amount (100 g or less) were kept in plastic zippered sample bags. The jars and sample bags were
kept in a dry, dark environment before being subjected to several leaching tests, including the TCLP test, the constant pH leaching
test, the Generalized Acid Neutralization Capacity (GANC) test and the variable mass leaching test. Test results were compared and
analyzed to determine if, for MPW, other leaching tests might give results different from the TCLP test.
2.2 Yerington, NV MPW
With help from Mr. David Reisman, USEPA, we received a variety of MPW samples (12 samples in all) from the Anaconda
copper mine in Yerington, NV. Based on the information in the Chain of Custody forms, four MPW samples with potentially high
oxoanion concentrations were chosen for digestion and preliminary analysis. This step was used to provide a primary screening of
the 12 original samples so that the one MPW sample with the highest concentration levels of oxo-anion forming elements could be
identified for further analysis. The sample selected was sub-sampled and analyzed as above.
2.3 Dearing, KS MPW
Near the end of the project, we received a third MPW sample from Dr. Souhail Al-Abed, USEPA. This sample came from a slag
pile at a lead and zinc smelter near the village of Dearing, Montgomery County, in southeastern Kansas. Although the smelter is no
longer in operation, heavy metals such as Pb and Cd that are contained in the slag are a matter of ongoing environmental concern,
especially considering the effort and expense involved in the currently recommended remediation treatment of digging up contaminated
soil and treating it as toxic waste. This sample was sub-sampled and analyzed by TCLP and Constant pH leaching procedures.
-------
3.0 MPW Characterization
Prior to the leaching studies, the Leadville and Yerington MPW samples were characterized by UC and by Agvise Laboratories,
Northwood, ND.
Total waste and chemical speciation analyses of the MPW samples were performed by Agvise Laboratories. These included
density, particle size, percent organic matter, cations (Ca, Mg, Na, K), pH and alkalinity. Data generated for the Leadville and
Yerington MPW samples by Agvise Laboratories are presented in Table 3-1 and Table 3-2. Table 3-3 lists the test procedures used
by Agvise Laboratories. The actual Agvise reports are presented in Appendix Tables B-l and B-2.

There was not enough time to do a complete characterization of the Dearing, KS waste. However, this waste has been previously
characterized by others. Table 3-4 provides selected chemical and physical properties of similar soils from this site for the <2 mm

Sample digestions and analyses for metals and oxoanions in all samples were performed at UC. The digestion method used
was Method 3010 in SW 846 (see Table 3-5). Because of equipment problems with our atomic absorption spectrophotometer we
switched from the proposed AAS analysis to using ICP machines housed with, and operated by, the Department of Chemistry Most
metals were analyzed on a TJA AES atomic emission spectrophotometer using EPA Method 601 OB. Arsenic was analyzed using
EPA Method 6020B and an Agilent ICP-MS. Total metal analysis results for the three wastes are shown in Table 3-6.

3.1 Leadville, CO Waste Characterization
The Leadville, CO waste had the consistency of soil and was characterized as similar to a loamy sand, with small amounts of
silt (6%) and clay (8%). It had a cation exchange capacity of only 1.45 gm/cc, and contained only 1.0% organic matter. Thus, its
capacity to bind heavy metals was low. Its particle density was 2.57, similar to that of sand. Its pH, though, was a very acidic 2.6.
It was stated by USEPA personnel who provided us with this waste sample that it would be high in lead and zinc (up to 5% and
14%, respectively) and in arsenic (>300 ppm). Lead was not analyzed for in this sample, but the zinc (274 mg/kg) and arsenic (22
mg/k'g) contents were found to be much lower than predicted. There was a considerable amount of iron (7,936 mg/kg). As these
were fluvial tailings, it is possible that the sample received contained more sediment than the samples previously analyzed. It is
possible that the sample received was not representative of the deposit at the site, or that many of the constituents had leached between
when the samples were first analyzed several years ago and when they were supplied to us. Nevertheless, we continued to use this
sample, as it did contain relatively significant oxoanion concentrations (As = 22 mg/kg, Se = 10 mg/kg). Little or no chromium,
molybdenum or vanadium was present.
3.2 Yerington, NV Waste Characterization
Twelve samples were obtained from the Yerington, NV site. Based on preliminary analyses, one sample was selected for further
testing. This sample was characterized as a sandy loam: 57.0 % sand, 41.0 % silt and only 1.0 % clay. The sample contained 4.9
% organic matter, and had a CEC of 18.9 meq/100 g. Its particle density was only 1.22.
-------
The Yermgton sample, which had a red color, contained large amounts of iron (48,780 mg/kg) and copper (1 766 me/kg) which
was expected for a copper mining waste. Oxoanion concentrations were much higW than ^LM^wSrS^M =
209mg/kg,Cr = 63mg/kg,Mo = 48mg/kg,Se=157mg/kg,V = 21mg/kg). '

4.0 Leaching
As stated earlier the MPW samples were sub-sampled according to the procedures laid out in the QAPP and then subjected to
several leach tests including the TCLP test, the Constant pH 5.0 Leaching Test, the Constant pH Leaching Test at Variable pHs, the
Generalized Acid Neutralization Capacity (GANC) test, and the Variable Mass Leaching test. For each test, the test method used
is presented in the appendix and the modifications to the method, if any, are presented in the following sections, together with the
results.
4.1 TCLP
The Toxicity Characteristic Leaching Procedure (TCLP) is a standard method that EPA replies on for teachability testing. In
this project, as stated in the QAPP, the TCLP test was performed following Method 1311 in SW 846. However, due to the limited
quantity of the MPW samples, the amount of sample used for the TCLP in this project was reduced to 50 ± 0.5 g each. The amount
of extracting liquid (TCLP fluid) was also reduced to approximately 1000 mL to keep the liquid/solid ratio at 20.
Triplicates were performed for the TCLP, i.e. the TCLP test was performed on three identical MPW samples. First, the MPW
samples were sieved to reduce the particle size to less than 9.5 mm. Depending on the water pH value of the sample, TCLP fluid
#1 or #2 was prepared for the extraction. A 50 ± 0.5 g sample was weighed and transferred into the TCLP jar. In order to maintain
the liquid/solid ratio of 20, approximately 1000 mL of TCLP fluid was added into the jar. The TCLP jar was closed tightly before
it was transferred to a tumbler for 18 hours agitation. After that, it was removed from the tumbler and the contents allowed to settle
for a short period of time. Then the suspension was filtered with the TCLP filter paper. The filtered extract was acidified and stored
in a refrigerator for analytical analysis.
TCLP results are presented in Table 4-1. TCLP QC data is presented in Appendix Tables C-4 to C-6 and is discussed in Section
5.0.

4.1.1 TCLP Data Evaluation
As can be seen from Table 4-1, all three samples had TCLP leachate concentrations well below the allowable limits, except for
cadmium in the Dearing waste. The Leadville and Yerington wastes would be deemed suitable for municipal landfill disposal for
the considered contaminants, based on the TCLP test.
The TCLP results were also normalized to the amount of solid waste, and expressed as mg of constituent in the leachate per kg of
waste material. These data are presented in Table 4-2. Based on the results in Tables 4-1 and 4-2, the percentages of each constituent
leached under the TCLP conditions were determined (Table 4-3). The amount leached during the TCLP test varied from element to
element and from waste to waste, but variations were relatively minor. Less than 10 percent of most metals leached. For

the oxoanions, very little arsenic, cadmium or vanadium leached, while the amount of molybdenum and selenium leached varied
from waste to waste. However, the concentrations of these last two in the wastes were very low to begin with.
4.2 Constant pH 5.0 Leaching Test
In order to be comparable to the TCLP test, the amount of MPW samples selected for use in the Constant pH 5 0 Leaching
Test was also 50 ±0.5 g Samples were put into the reactor along with a magnetic stirrer. The initial pH value of the leachant was
5.0. Acid (0.1 N HN03) and/or base (0.1 N NaOH) were added into the reactor to maintain the PH value constant using a PH stat
system. Continuous stirring was employed to keep the mixture homogeneous. The leachate was sampled at defined intervals The
sampling time and the volume of leachate were also recorded. Leachate samples were filtered and stored in the refrigerator for further
analysis. Constant pH leaching test data for pH 5.0 leaching are provided in Tables 4-4, and 4-5 for the Leadville and Yerington
wastes, respectively. This test was not performed on the Dearing waste, but similar results can be seen in Table 4-8.
4.2.1 Data Analysis
Examination of the data presented in Tables 4-4 and 4-5 shows that, in almost all cases, leaching reached an equilibrium fairly
quickly, generally within one day. Figure 4-1 shows the amount of arsenic leaching as a function of time for the Leadville CO and
Yerington, NV MPW samples. There was an immediate high degree of leaching, probably caused by surface washoff, followed by
a constant leachate arsenic concentration. Other wastes leached in a similar fashion. Thus, the 18-24 hour leaching time used in the
TCLP test is probably appropriate. It can also be seen, though, that acid had to be continually added to maintain the pH 5 0 goal
The results from this test should be comparable to the TCLP test, in that they both have an objective of leaching at a pH of ~5 0 The
difference between them is that the TCLP test has all of the required acid added at once, while the Constant pH test only adds acid
as needed to maintain the desired pH. There is no guarantee that the final TCLP pH will be 5.0, because the amount of acid added
according to the TCLP protocol may not be sufficient to maintain it at 5.0. On the other hand, there may be a surplus of acid at the
beginning of the test. The constant pH test overcomes these potential problems.
Table 4-6 shows that, in general, the metals leached under the Constant pH conditions and the TCLP leaching test are of the same
order of magnitude, although there is some variability between them. This variability may be due to the differences in equilibrium
pH discussed above. The amounts of oxoanions leached under the two leaching conditions are quite similar.
4.3 Constant pH Leaching Test at Variable pH
In addition to the constant pH leaching test procedure described in the QAPP, another set of constant pH leaching
tests was also performed for all three MPW samples. These MPW samples were tested at varying pH levels with the
pH level kept constant at the desired pH throughout the test. The pH levels chosen for this test were 3, 5, 7, arid 9 Four
identical 50 g MPW samples were put into four reactors, with the leachant inside maintained at pH levels of 3', 5, 7 and 9

respectively, using a pH stat system. Acid (HNO3) and/or base (NaOH) were added into the reactors as necessary to keep the pH
levels constant. The resulting leachates were sampled at selected time intervals. These samples were filtered and refrigerated for
analysis. Results of the Constant pH Leaching Test at the selected pH values are presented in Tables 4-7 to 4-9.
4.3.1 Data Analysis
The Constant pH leaching test results under different leachant pH conditions (Tables 4-7 to 4-9) can be used to evaluate the
influence of pH on metal leaching. Results for 24 hours of leaching are summarized in Table 4-10. Many of the elements were
non-detectable at higher pH values. This is not surprising, because most metal cations have a lower solubility at pH values above
neutral compared with below neutral. Most of the oxoanions were also below their detection limits (D.L • 1 ue/L As 1 ue/L Mo 2
(Ug/L Se, 4 ug/L V) when the pH was above 5.0. '
4.4 GANG Test
The GANG test performed in this project followed the standard method stated in the QAPP. MPW samples were dried ground
and sieved to 9.5 mm or less. A total of 63 samples of 1.000 ± 0.005 g were put in triplicate into HOPE bottles containing the
appropriate leachant at 21 different pH levels. All the bottles were closed tightly and tumbled for 48 hours The pH values of the
leachates were then measured. Results are presented in Tables 4-11 and 4-12 for the Leadville, CO and Yerington NV MPWs and
are also plotted in Figures 4-2 and 4-3, respectively. The GANG test was not performed on the Dearing, KS sample.
The results presented indicate that the samples had essentially no acid neutralization capacity.

4.5 Variable Mass Leaching Test
The Variable Mass Leaching Test was investigated for use with the Leadville sample. However, this test is designed for
use with permeable, but solid, wastes such as solidified/stabilized wastes. The test is performed to measure acid penetration rates
into a solid and the resulting leaching rates. However, these MPW solids were granular in nature, and the acid did not penetrate
It was determined that the Variable Mass Leaching test was not applicable to MPW-type wastes and was not appropriate for this
project. There was little of significance discovered in terms of leaching from MPW wastes. Therefore, this test was abandoned for
this project. Nevertheless, the original data is provided in Appendix Table B-9.

5.0 Data Quality Discussion
The QC results can be found in the data files in the appendices, Tables C-1 to C-12. Certified QC standards were used throughout.
During the analyses in this project, which included ICP-AES analysis, ICP-MS analysis and pH measurements, the QC checks
indicated that the data quality in this project met the requirements in the QAPP most of the time, but there were lapses.
Table B-5 presents a summary of the metal analyses performed on the three MPW waste samples. This includes the average
results for metals in the digestates, TCLP leachates, and constant pH leachates. The percent leached is also given. In addition, the
relative deviations (R.D.) between the TCLP test results and the constant PH test results are provided. These indicate a large percent
variation, but this is largely due to the small concentrations present. Small differences in concentration can lead to large relative
deviations.
The QC data for these MPW samples is provided in Appendix Tables C-l, C-2 and C-3 for the Leadville, CO; Yerington, NV;
and Dearing KS samples, respectively. There is some question about the copper results for the Leadville, CO, waste because the
check standard values were out of the range specified in the QAPP. The copper results may be biased high. However copper was
not an element of concern under analysis in this project. There was no precision or accuracy data for Leadville sample #4, but all
others were acceptable. Except for a few blanks that were slightly high, all other results were within limits.
Table B-6 presents a summary of the ICP-AES results. As can be seen, the standard deviations between replicates are generally
small.
Tables B-7 and B-8 present data from the GANG test on the Leadville and Yerington MPW wastes. Three replicates were run
on each sample. A comparison of the data indicates that there was little variation between the three replicates.
Table B-9 presents all of the raw metals analysis data for all of the experiments. This includes all analyses, standards checks,
blanks, etc.
Finally, Table B-10 summarizes the ICP data with measurement ranges. Again, there was very little variability between
measurements.
Tables C-4 C-5 and C-6 present a QC analysis of the TCLP data for the Leadville, CO; Yerington, NV; and Dearing, KS,
samples respectively. The accuracy of these analyses and the blanks were in the acceptable range. There was one copper result for
the Leadville MPW that was much too high, throwing the precision for this analysis off. It appears that this might be a decimal error.
The result was ten times higher than the other replicates. If this is the case, the results become acceptable. Variability in copper,
iron and selenium was higher than expected. Some of the Yerington measurements are suspect. Sample-to-sample comparisons
are good but some sample measurement precision and check standards are less than acceptable. For the Dearing MPW, sample-
to-sample variability was acceptable for all but iron and selenium. Some of the blanks were a little high, which may have affected
these results. The check standards accuracy was good.
Tables C-7 and C-8 show the QC data for the Leadville and Yerington samples subjected to the Constant pH 5.0 leaching test.
In all cases, the blanks were high. Some of the check standards were less than acceptable for the Leadville MPW, but most were
within range for the Yerington waste. There was no precision data available.
Tables C-9 C-10 and C-l 1 present QC data for the three wastes subjected to leaching at constant values of pH 3, pH 5, pH 7
and pH 9. There is one suspect blank data point for vanadium in the Leadville sample and one blank for the Yerington sample that
registered zinc. All other data look fine, except that a few of the vanadium recovery values exceeded limits specified in the QAPP.
The QAPP minimum detection limits (0.05 - 4 //g/L) and precision (5%) and accuracy (± 10-25%) standards set in the QAPP
were much more stringent than is common for research of this type. More realistic values, such as those found in EPA SW 846
Method 6010B, would have been met in almost all cases. Thus, although the precision and accuracy of some of the data were below
19
-------
QAPP standards and may be considered suspect, the magnitude of the values and the leaching trends determined would not have
changed.
m * w , 1JmitS Specified in ^ QAPR However' the metal concentrations
present in the MPW samples were generally quite low and the resulting TCLP leachate concentrations were well below the allowable
limits. It is not likely that more precise measurements would have caused the results to exceed the TCLP limits.

6.0 Conclusions
Based on the results presented, several conclusions can be made:
1 Mineral processing wastes vary widely in composition and characteristics. The three samples tested varied in physical
characteristics, with one being classified as similar in texture to a loamy sand, one a sandy loam, and the third a silty sand.
Organic contents varied from 1.0% to 4.9% Particle densities varied from 2.57 g/cc to 1.22 g/cc, and cation exchange
capacity varied from 13.6 meq/g to 45.6 meq/g. Unfortunately, since this study focused on leaching of oxoanions, the samples
contained smaller quantities of these materials than hoped for.The Yerington, NV sample was the highest, with 209 mg/kg
As and 156 mg/kg Se.
2. All three samples had TCLP leachate concentrations for the elements studied well below the allowable limits, as shown in
Table 4.1, except for cadmium in the Dearing waste. The Leadville and Yerington wastes would be deemed non-hazardous,
and suitable for disposal in a municipal solid waste landfill, based on the TCLP test. The amounts leached during the TCLP
test varied from element to element and from waste to waste, but variations were relatively minor. Less than 10 percent of
most metals, including cadmium, leached. For the oxoanions, very little arsenic or vanadium leached, while the amount of
molybdenum and selenium leached varied from waste to waste. However, the concentrations of these last two in the wastes
were very low to begin with.
3. Mineral processing wastes vary widely in composition and characteristics. The three samples tested varied in physical
characteristics, with one being classified as similar in texture to a loamy sand, one a sandy loam, and the third a silty sand.
Organic contents varied from 1.0% to 4.9%. Particle densities varied from 2.57 g/cc to 1.22 g/cc, and cation exchange
capacity varied from 13.6 meq/g to 45.6 meq/g. Unfortunately, since this study focused on leaching of oxoanions, the
samples contained smaller quantities of these materials than hoped for. The Yerington, NV sample was the highest, with
209 mg/kg As and 156 mg/kg Se.
4. All three samples had TCLP leachate concentrations for the elements studied well below the allowable limits, as shown in
Table 4.1, except for cadmium in the Dearing waste. The Leadville and Yerington wastes would be deemed non-hazardous,
and suitable for disposal in a municipal solid waste landfill, based on the TCLP test. The amounts leached during the TCLP
test varied from element to element and from waste to waste, but variations were relatively minor. Less than 10 percent of
most metals, including cadmium, leached. For the oxoanions, very little arsenic or vanadium leached, while the amount of
molybdenum and selenium leached varied from waste to waste. However, the concentrations of these last two in the wastes
were very low to begin with.
5. Oxoanion leaching reached an equilibrium fairly quickly, generally within one day. There was an immediate high degree
of leaching, probably caused by surface washoff, followed by a constant leachate arsenic concentration. Thus, the 18-24
hour leaching time used in the TCLP test is probably appropriate. In general, the metals leached under the Constant pH
5.0 conditions and the TCLP leaching test are of the same order of magnitude, although there is some variability between
them. The amounts of oxoanions leached under the two leaching conditions are quite similar.
6. Leaching tests run at several constant pH values between pH 3.0 and 9.0 were used to evaluate the influence of pH on metal
leaching. Results indicate that 24 hours of leaching is sufficient, and that many of the elements were non-detectable at
higher pH values. This is not surprising, because most cationic metals are generally more soluble at lower pH. Most of the
oxoanions were also non-detectable above pH 5.0. This is contrary to many previous studies that found increased arsenic
leaching at higher pH. This may possibly have occurred here because of the relatively low arsenic concentrations present
in the wastes.
7. The Variable Mass Leaching test and the SUC (Shrinking Unreacted Core) leaching tests are not suitable for mineral
processing wastes because they are designed for use with permeable, but solid, wastes such as solidified/stabilized wastes.
21
-------
The tests are performed to measure acid penetration rates into a solid and the resulting leaching rates. However these MPW
solids were granular in nature, and the acid did not penetrate. Consequently, they should not be used for particulate (* 0 5
mm) MPW samples. v v '
8. Based on the results of this study, using this set of MPW wastes, it is concluded that there is no difference in the amounts
of contaminants leached between the leaching methods studied. The TCLP test procedure is simpler than other available
S^^Tn, r!SUltS °,btained from me TCLP test *« comparable to those from other, more demanding test procedures
ine 1CLP leaching solution pH of 5.0 appears to be appropriate for MPW wastes, as is the 18-24 hour leaching period It
must be reiterated, though, that two of the three wastes evaluated did not contain high levels of oxoanions, and the one that
did exhibited a very low degree of leaching. Other wastes might exhibit different leaching behaviors
22
-------
7.0 Recommendations
The following recommendations can be made, based on the findings from this research:
1. It is recommended that use of the TCLP test for mineral processing wastes be continued, as it provides results comparable
to those from other leaching protocols studied.
2. A wider range of MPW wastes, that have been shown to leach oxoanions, should be evaluated.
