DEVELOPMENT OF RATIONAL SCHEME OF CONCENTRATION OF REST GOLD-BEARING ORES TAKING INTO ACCOUNT THEIR TECHNOLOGICAL FEATURES

摘要

Gravitational-flotation scheme for concentration of rest gold-containing and arsenic-containing ore, including dual-stage comminution and gold extraction into gravitational and flotation sulfide concentrates with intracycle shale flotation in the first stage of comminution, has been developed. The new reactant flotation conditions were proposed in order to rise the gold extraction into sulfide concentrates.
