摘　　要：针对南美某含钼0.027%、含铜0.45%的低品位铜矿进行了选矿试验研究。应用适宜的浮选药剂,采用铜钼混合浮选-铜钼分离流程,闭路试验获得了铜品位26.93%、铜回收率81.96%的铜精矿和钼品位25.32%、钼回收率76.24%的钼精矿,铜、钼资源得到有效回收。Mineral processing tests were carried out for a low-grade copper ore from South America containing 0.027%Mo and 0.45%Cu.After optimization of the reagent regime,a close-circuit test by adopting a flowsheet of Cu-Mo bulk flotation plus Cu/Mo separation resulted in a copper concentrate grading 26.93%Cu at 81.96%recovery,and a molybdenum concentrate grading 25.32%Mo at 76.24%recovery.Therewith,copper and molybdenum resources in the lean ore can be effectively recovered.
