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-74μm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%。
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%.
