An experimental study was carried out on the fluidized bed roasting of copper?cobalt sulfide concentrate obtained after processing of copper?cobalt ores from Congo DRC. It is suggested that a better effect be obtained for the roasting of copper?cobalt concentrate at a temperature of 620℃, with linear velocity of air at 0.43 m/s, air/ore ratio of 3.33 m3/kg. The further acid leaching test of calcine and roasting dust testified the optimum roasting condition. The leaching rates of Cu, Co, Fe reached 96. 43%, 87. 06%, 10. 89%, respectively, from the calcine, and 96. 32%, 84?02%, 17.12%, respectively, from the roasting dust. The experiment result can provide some sort of experimental reference and technical support for the selection of a combined process of concentrating and metallurgy, as well as the following industrialization of fluidized bed roasting technique for such copper?cobalt sulfide concentrate in future.
