RESEARCH ON THE PREFERENTIAL FLOATATION FOR CHALCOPYRITE BY USING NEW COLLECTOR BK-330

Cheng Xin-chao

Abstract

BK-330 produced recently by BGRIMM is a new sulphide mineral collector.A series of flotation experiments of chalcopyrite and pyrite are conducted by using BK-330,Z-200 and xanthate under different conditions.It is concluded that the new collector BK-330 has stronger flotation power towards chalcopyrite than pyrite.Therefore BK-330 is a strong selective collector.
