The chemical technology for recovery precious metals Au and Ag from mature flotation tailings of copper-pyrite ores by two-stage sintering with chlorine-ammonium reagents and leaching of bakes with water is developed. The chemical extraction of gold and silver is carried out, using NH4Cl and NH4NO3 reagents in the ratios of 1:1 at a temperature of 250 °C, and 2:1 at 200 °C. In accordance with the obtained results, a chemical technology of enrichment rejects of copper-pyrite ores processing and a scheme of primary apparatus chain for implementing this technology are proposed. The economic effect of the technology realization is calculated. This effect is 96.3 million rubles with a payback period of 8 years when processing enrichment rejects of copper-pyrite ores in amount of 109.5 thousand tons per year under the conditions of JSC “Uchaly Mining and Metallurgical Combine”.

The article discusses issues related to the production waste of Stepnogorsk Mining and Metallurgical Combine (SМMС). The greatest danger to the environment is represented by radionuclides. Soil types and their resistance and ability to accumulate radionuclides are considered. It is also noted that harmful radioisotopes spread through the soil and atmosphere and the maximum permissible concentration (MPC) of these substances decreases from the source of their storage and this is due to the fact that different soils have different conductivity of these harmful substances. The article also identifies opportunities to reduce the impact of SМMС wastes on soil and vegetation, as well as the atmosphere near a dangerous source of radiation infection.
