FIELD: metallurgy.
SUBSTANCE: method consists of ore crushing, differential flotation of sulfide copper minerals into the concentrate by successive addition of reagents - collector and foaming agent and differential flotation from the rest pulp into the other concentrate of oxidised copper minerals by successive addition of reagents - sulphidiser, foaming agent, collector, liquid glass modifier. At differential flotation of sulphide and oxidised copper minerals after addition of each of reagents it is implemented conditioning during 1-3 min. In the capacity of collector it is used butyl xanthate, and in the capacity of foaming agent - reagent T-80 in amount 30-60 g/t.
EFFECT: flotation effectiveness increase.
