depressors in mineral processing An analysis of experimental data and research in the field of nonferrous ore beneficiation indicates that the conventional processing technologies currently in use have been developed for readily upgradable ores and do not ensure high performance values ...

Depressors | definition of depressors by Medical dictionary

Early research work carried out some 12 years ago by the Department of Mineral Processing at the Faculty of Mining and Geology, Belgrade University, had as its objective the replacement of ZnS[O.sub.4] with another, more efficient modifier which could offer, apart from successful depression of sphalerite, a lower depressor consumption[1].

Technology for separation of non-ferrous metal minerals ...

Jan 01, 2000· Up to 50% of copper is recovered into the "copper head" with a minimum requirement of collector (1 +5 g/t) and depressors (20 g/t of sodium sulfide, 100 g/t of zinc sulfate). Classical processing technology is used for most ores including separation of bulk concentrate with subsequent copper and zinc flotation steps.

Depression of pyrite mineral with cyanide and ferrous ...

This paper presents the results of the examination of depressing effect of cyanide salts type reagents (NaCN, K3[Fe(CN)6] and K4[Fe(CN)6]), as well as ferrous/ferric salts (FeSO4 and Fe2(SO4)3) on the floatability of pyrite in the presence of xanthate as collector. The examinations show that all tested depressants reduce the collection ability of pyrite with K-butyl xanthate (KBX).
