METHOD FOR CONTROLLED FINISHING OF ROUGH COPPER-NICKEL CONCENTRATES

METHOD FOR CONTROLLED FINISHING OF ROUGH COPPER-NICKEL CONCENTRATES

FIELD: nonferrous metallurgy, in particular, concentration of copper-nickel ores. SUBSTANCE: method involves additional grinding and reflotation of rough copper-nickel concentrates by means of soda, carboxymethyl cellulose, copper sulfate, xanthate, aerofloat and machinery oil. Machinery oil is dose...

description FIELD: nonferrous metallurgy, in particular, concentration of copper-nickel ores. SUBSTANCE: method involves additional grinding and reflotation of rough copper-nickel concentrates by means of soda, carboxymethyl cellulose, copper sulfate, xanthate, aerofloat and machinery oil. Machinery oil is dosed into process depending on speed of motion and extent at which froth is charged with sulfide minerals. Method allows cases when flotation machine fails to skim froth to be excluded and, as a result, extraction of nickel into concentrate to be increased. EFFECT: increased efficiency and improved extraction of nickel. 1 dwg
