FIELD: concentration of mineral resources. SUBSTANCE: method of flotation separation of collective copper-zinc concentrate consists in pulp conditioning by a zinc-containing reagent in the presence of sodium sulfide and subsequent separation of copper concentrate to a froth product, mechanoactivated zinc concentrate is used as zinc-containing reagent; the relation between mechanoactivated zinc concentrate and sodium sulfide is from 15:1 to 30: 1; mechanoactivated zinc concentrate is introduced within 3 to 6 kg/t of ore. EFFECT: facilitated procedure. 3 cl, 1 dwg
