| Abstract/Notes | Geochemical zoning of the high-sulfi de (40–45 wt.% sulfides) and low-carbonate (3 wt.% dolomite) waste at the Berikul gold mine, Kemerovo region, Russia, was studied in order to understand the processes controlling As, Cd, Cu, Pb and Zn migration from the waste. The following zones were distinguished from bottom to top: (1) slightly altered waste, (2) cemented hardpan zone, (3) melanterite zone, (4) intermediate zone and (5) jarosite zone. A sequential scheme of extraction was used to separate (a) water-soluble, (b) exchangeable, (c) carbonate, (d) phases bound with Fe3+, and (e) residual fractions of Fe, As, Zn, Cu and Cd. The two basal zones refl ect an early stage of weathering, where acid generated by sulfi de oxidation is neutralized by carbonate. Neutralization processes promote coprecipitation of As, Cd, Cu, Pb and Zn in Fe3+ phases, such as amorphous Fe sulfo-arsenate and jarosite. An intermediate stage, recorded in the melanterite and intermediate zones, is identified by the disappearance of the carbonates and a decrease in the pH of pore solutions. At low pH, sulfi des are oxidized by Fe3+, producing Fe2+, SO4 2–, and liberating As, Zn, Cu and Cd, which accumulate in the pore water. This step results in the precipitation of Zn-, Cu- and Cd bearing melanterite. The intermediate stage of weathering continues until most of the sulfide fraction has been oxidized. Then, as shown in the upper jarosite zone, the concentration of Fe3+ again increases in the pore waters because it is not being utilized in sulfide oxidation, and Fe3+ phases, such as jarosite, precipitate. By this stage, significant amounts of As, Zn, Cu and Cd have been leached from the weathered residue, but Pb precipitates in the jarosite. | ||
