Flotation tests were conducted for a low-grade copper-nickel sulfide ore with high content of mud and magnesium oxide from Xinjiang. Using sodium carboxymethyl cellulose and sodium silicate as a combined inhibitor, butyl xanthoxanthate and butyl ammonium black as a combined collector, a closed-circuit test with a flowsheet consisting of a Cu-Ni bulk flotation and a Cu/Ni separation produced a copper concentrate grading 25.11% Cu at 79.90% recovery, with MgO content of 2.02%, as well as a nickel concentrate grading 6.98% Ni at 75.01% recovery, with MgO content of 5.32%. It is concluded that effective recovery and separation of copper and nickel can be actualized.
