FIELD: technological processes.
SUBSTANCE: invention relates to floatation extraction of sulfide minerals containing noble metals, from concentrates, and may be used in floatation enrichment of sulfide pyrite-arsenic pyrite ores, which contain noble metals. Method includes conditioning of ground pulp with sulfhydric collector, introduction of surface modifier, depressor and foaming agent, and extraction of pyrite concentrate into foam product of floatation. As surface modifier, 2-oxypropyl ether of diethyl dithiocarbamic acid, and depressor is represented by extract of oak bark.
EFFECT: improved efficiency of pyrite and arsenic pyrite separation.
