Abstract

The main method of beneficiation of copper ores is flotation. Copper and copper-pyrite ores are easily beneficiated. The applied scheme and technological procedures depend on the type of ore being processed, the composition of copper minerals, their state and susceptibility to leaching, the presence of primary sludges and soluble salts, as well as the nature of mixed rocks.       In copper-pyrite deposits, sulphide minerals are found in the form of chalcopyrite, chalcosine, bornite and pyrite, their total amount is 3-4%, where the relative share of pyrite is much larger than other sulphides. In the oxidation zone, these sulfides preserve malachite, azurite, brochantite, chrysocolla, and other oxidized copper minerals. 10-15% of the total amount of oxidized copper deposits are sulphide, 10-15% to 50-75% are mixed, and 50-75% are oxide ores. Sulphide ores are more industrially important, as they make up 90-95% of this type of ore reserves.
