Sulphidizing Flotation of Copper Oxide Ore

Abstract:

The copper oxide ore in Dali, which contains 0.69% of copper and 11.24g/t of silver, was beneficiated by sulphidizing - xanthate flotation method. The flotation tests were carried out systematically with sodium sulfide as sulphidizing agent and butyl xanthate + ammonium dibutyl dithiophosphate as the combined collectors. Through closed-circuit test, a copper concentrate with 18.34% of Cu grade and a recovery of 70.13% were obtained. In addition, silver also was enriched in copper concentration with a grade of 329.37g/t and a recovery of 78.79%, which is convenience for utilization in metallurgical processes.
