新疆某微细粒铜矿石选矿试验研究

在对新疆某铜品位为0.52%、钼品位为0.028%的细粒嵌布铜矿石进行矿石性质分析的基础上，进行了浮选工艺条件研究。研究结果表明，该铜矿石在磨矿细度为-0.074 mm占90.60%的条件下，以丁基黄药与Z-200为组合捕收剂（质量比为1∶4），采用1粗3精2扫、中矿顺序返回的闭路流程处理，可以获得铜品位为20.52%、铜回收率为92.54%、含钼0.95%、钼回收率为78.04%的铜钼混合精矿。

Experimental Research on Mineral Processing For Some Micro-fine Copper Ore from Xinjiang

Based on the analysis to a fine-disseminated copper ore with Cu grade 0.52%,molybdenum grade 0.028% from xinjiang,carried out the research on floatation process.The results show that: under the conditions of grinding fineness of-0.074mm 90.60%,buty1 xanthate and Z-200(mass ratio 1∶4) as collectors,through once roughing three times cleaning twice scavenging,middlings orderly return,can get the Cu-Mo mixed concentrate with Cu grade 20.52%,recovery 92.54% and Mo content 0.95%,recovery 78.04%.
