| Abstract: | Flotation tests were conducted to reclaim copper resources from copper smelting slags in Kangxi Copper Smeltery. The results show that a close-circuit test by adopting a flowsheet consisting of one roughing and two scavenging processes, with grinding fineness of -43 μm 80%, pulp concentration of 40%, lime dosage of 1 000 g/t, 300 g/t of Na2S for roughing process and 100 g/t of Na2S for scavenging process, can result in a copper concentrate grading 27.64% Cu at 94.25% recovery. |
