| Abstract: | Laboratory study on Cu-S separation for a refractory copper-sulfur ore was carried out. The raw ore contains 0.586% of copper and 11.22% of sulfur, and the secondary copper therein accounts for 0.171% while the oxidation rate of copper minerals attains 9.22%. Selective flotation approach was adopted with lime as pyrite depressant, ammonium dibutyl dithiophosphate and butyl xanthate (1〖DK〗∶1) as combined collector for copper, and HT as the regulator. A copper concentrate with copper grade and recovery of 20.55% and 85.92%, respectively, and a sulfur concentrate with sulfur grade and recovery of 37.13% and 91.69% respectively, can be collected in the closed-circuit test. |
