METHOD FOR FLOATING SEPARATION OF COLLECTIVE SULFIDE COPPER/ZINK CONCENTRATE Russian patent published in 1995 - IPC

Abstract RU 2042431 C1

FIELD: minerals beneficiation. SUBSTANCE: method for floating separation of collective sulfide copper/zink concentrate includes electrochemical treatment, adding depressing agents in the pulp such as sodium sulfide and zinc sulfate, aftergrinding and forming copper concentrate as foam product; collective sulfide copper/zink concentrate is subject to electrochemical treatment before adding depressing agents in the pulp with redox potential ranged from 0.35 to 0.45 V. Electrochemical treatment lasts for 5 to 10 min. EFFECT: high productivity. 2 cl, 1 dwg, 1 tbl
