Mining activities in Russia, associated with coal and mixed sulphide ores and concentrates generate every year, millions of tons of hazardous wastes, which
are stockpiled in the vicinity of major cities (Moscow, Ekaterinenburg, etc). These wastes are oxidized, due to the action of precipitation, oxygen and bacteria
and therefore, acidic waters and leachates with a very low pH and high concentration s of heavy and toxic elements are generated. These leachates migrate and
contaminate severely major lakes, rivers and groundwater reservoirs, endangering thus the quality of the environment and the health of million of people.
The present proposal, aims at the development and application of preventative and remedial technologies in order
a) to decontaminate the hazardous wastes,
b) clean up the effluents and
c) isolate hazardous waste dumps, in order to eliminate all these active pollution sources and protect the environment.
