Mining activity entails accumulation of sulfide?bearing mill wastes with high concentrations of ore elements (Fe, Cu, Zn, Cd) and impurities (As, Hg, Be, and Tl). The volumes of hazardous sulfide-containing mining waste in non-equipped storage facilities according to modern standards reach several billion tons in Russian Federation. The handling of abandoned waste in our country is not currently regulated, the question remains open: there is no established methodology for estimating stockpiles and handling of wast...

The studied tailing dump is located on a hill in the urban village limits (Komsomolsk, Kemerovo region) and contained cyanidation wastes. There are the comprehensive school and the central street of the city below a hill, and the kindergarten on the opposite hill. Due to the easy availability of atmospheric oxidizing factors, the material of the bulk dumps changes very quickly, and, of course, seeps into the hill. Two types of streams interact with the material of the Berikul bulk dumps: infiltration water that se...

The relevance of the work is dictated by extensive environmental pollution in the areas of mining waste storage by chemical elements of 1-3 hazard classes (Hg, Be, As, Fe, Cu, Zn, Cd, Pb, Co, Ni, Mo, Ag, and Sb). The interaction of crushed sulfide-containing wastes with surface waters and atmospheric precipitation contributes to the formation of highly mineralized technogenic solutions with element concentrations exceeding the background and maximum permissible values several orders of magnitude. Land and water re...
