Summary

The main part of copper-pyrite ores reserves of Russia is concentrated on the fields of South Ural, where technogenic fields are widespread, consisting of mining, concentrating, metallurgical and other productions waste suitable for industrial use. Analysis of chemical composition and mineral content in ash-slag mixtures and dumps of some mining and processing plants showed that tails contain 0.05-0.17% copper and 0.05-0.37% zinc. The highest content of zinc was found in dumps of Uchalinskiy mining and processing plant, comparable to those in extracted ores. Gold content of 0.8-1.2 g/t was found in pyrite concentrate from Gaisky mining and processing plant. Sulfuric acid waste water is generated due to natural geochemical processes, contaminating land and water.
