CRYOGEOCHEMISTRY OF OXIDATION ZONE OF SULPHIDIC DEPOSIT UDOKAN (EAST TRANSBAIKALIA)

Эпова Е.С.
The experimental leaching of the sulphidic and oxidized Udokan copper ores by sulfuric acid solutions of different acidity for various temperatures have been carried out. The complex of chemical elements including potential toxicants as Cu, Pb, Cd, Be have been determined. The group of elements - Cu, Ag, Pb, Al, Ti, Zr, P is characterized by the high mobility in permafrost conditions of Udokan deposit. On the basis of the received data and ores analysis the parameter of potential toxicity of a deposit according to a technique [2] is calculated. The acid mine drainage processes ‘ll be activate the heavy metals mobility with geochemical transformations and negative affect on the Udokan geosystems.
