Abstract

The conducted studies prove the necessity to increase the hazard class of waste from the pyrometallurgical processing of Severonickel enterprise due to erosion and hypergenic processes, which cause water pollution with toxic metals and sharp decrease in pH level. Formation of acidic waters leads to transformation of the composition of cover sediments, surface and ground waters, as well as to increase of migration ability of polluting elements. Criterion dependences of transformation of mineral and chemical composition of mining and metallurgical wastes are established. The ways to reduce the technogenic load on the soil and vegetation cover and natural waters in the acidification zones are proposed: construction of a geochemical barrier for old, already stockpiled waste and change of the enterprise technology at the stage of slag formation and transportation.
