Abstract RU 2124573 C1

FIELD: hydrometallurgy. SUBSTANCE: method includes processing of copper ores or concentrates containing gold with simultaneous leaching, both, copper and gold by cyanide solution with molar ratio of CN:Cu > 3.5:1 with subsequent separation from solution of copper and gold by electrolysis or cementation and regeneration of cyanide ions. EFFECT: higher efficiency of processing ores with high concentration of cyanide-soluble copper minerals with low content of gold. 22 cl
