FIELD: metallurgy.
SUBSTANCE: method involves crushing of initial ore to fraction size of 30÷80 mm. Then there performed is heap leaching, extraction, re-extraction and electric extraction of cathode copper from liquid phase of leachant. After leaching the final crushing of solid leachant phase and floatation of finally crushed solid phase is performed at pH=7-8 created with caustic soda so that copper concentrate is obtained and gold is extracted to it.
EFFECT: development of high-effective processing method of mixed copper ores, which allows reducing operating costs and achieving optimum extraction properties of copper and precious metals.
