摘要： 采用铜铋混合浮选—铜铋分离浮选工艺和新型有机抑制剂XTL-3处理江西某铜铋多金属矿石，实现了铜和铋的高效无氰分离。试验在-74 μm占70％的磨矿细度下，获得了铜品位和铜回收率分别为27.51%和88.71%的铜精矿及铋品位和铋回收率分别为20.14%%和77.58%的铋精矿，铋在铜精矿中的含量为0.14%，铜在铋精矿中的含量为2.13%。

Abstract: The Cu-Bi multi-metal ores in Jiangxi were treated by adopting the Cu-Bi mixed flotation - Cu-Bi separation flotation techniques with new type of organic depressant XTL-3 to realize the high efficient Cu-Bi cyanide-free separation. With the grinding fineness of -74 μm 70%, copper concentrate grading of 27.51% at an 88.71% recovery and bismuth grading of 20.14% at a 77.58% recovery were obtained respectively. Meanwhile, Bismuth content in copper concentrate is 0.14%, and Copper in bismuth concentrate is 2.13%.
