METHOD OF FLOTATION SEPARATION OF SULFIDE COPPER-ZINC-PYRITIC CONCENTRATES, THAT HAVE ZINC SULFIDES ACTIVATED BY COPPER AND CALCIUM CATIONS Russian patent published in 1996 - IPC

Abstract RU 2054971 C1

FIELD: mineral resources beneficiation. SUBSTANCE: pulp is conditioned with sulfuric sodium and zinc sulfate in alkaline medium. Collector and foam maker are introduced. Flotation is carried out. Copper sulfides and pyrites are carried off into foam product. Zinc concentrate is produced as chamber product. Mercaptobenzothiazole is additionally introduced in pulp conditioning process. Consumption ratio of sulfuric sodium zinc sulfate and mercapto benzothiazole is from 1.000 : 4.660 : 0.007 to 1.000 : 2.330 : 0.027. EFFECT: increased productivity. 1 tbl
