METHOD OF FLOTATION OF SULPHIDE COPPER-NICKEL ORE

摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to concentration of ores of nonferrous metals and can be used in concentration of sulphide copper-nickel ores. Method involves crushing and conditioning of ore in presence of sulfhydryl collector - potassium butyl xanthogenate and foaming agent, extraction of nickel and copper minerals into collective concentrate and minerals of waste rock in final tailings. In addition to collector butyl xanthogenate bis(2,2,2-trifluoroethyl)ethyl phosphite is introduced, at following ratio, wt%. %: butyl xanthogenate - 50, bis(2,2,2-trifluoroethyl)ethyl phosphite - 50.;EFFECT: technical result is increase of technological parameters of flotation process and wider range of used flotation reagents.;1 cl, 1 tbl, 1 ex
