METHOD FOR FLOTATION SEPARATION OF SULFIDES Russian patent published in 2005 - IPC

Abstract RU 2248248 C1

FIELD: flotation concentration of non-iron metal sulfide ores.

SUBSTANCE: claimed method includes conditioning of sulfide-containing slurry in alkali medium with collector, foaming agent, and alkali metal dimethyldithiocarbamate. In foamed product one from sulfide is derived, and second or residual sulfides are derived in form of chamber product. Conditioning is carried out without aeration.

EFFECT: increased flotation selectivity.
