| Abstract: | Conditions of copper minerals flotation from copper-bearing pyrite is studied. A set of copper-sulfur separation process was developed. Using combined depressants the pyrite is effectively inhibited. Good indexes of flotation can be obtained in laboratory tests by one-roughing, two-cleaning and two scavenging flotation flowsheet. The grade of copper concentrate is 20.31% and copper recovery rate is 90.82%. |

| Keywords: | copper-bearing pyrite flotation high sulphur content copper-sulfur separation |
