摘要:
西藏某次生铜矿为铜铅混合矿石，铜矿物主要以辉铜矿形式存在，铅矿物以方铅矿形式存在。通过探索试验可知，该矿石所得精矿中铜、铅2种元素分离困难，故最终确定采用优先选铜再选铅的浮选流程，采用抑制剂YS02和YS04可实现对方铅矿的有效抑制，高选择性捕收剂BS09可获得铅品位合格的铜精矿。在磨矿细度-0.074 mm占比65 %，选铜作业流程为一次粗选三次扫选，选铅作业流程为一次粗选三次扫选三次精选条件下获得铜品位24.63 %、铜回收率81.05 %的铜精矿，铅品位45.59 %、铅回收率81.32 %的铅精矿，试验指标较为理想。

Abstract:
A secondary copper ore in Xizang is mixed copper-lead ore,with copper primarily in the form of chalcocite and lead in the form of galena.Experimental exploration revealed that separating copper and lead in the result-ing concentrate from this ore is challenging.Therefore,a flotation process prioritizing copper separation followed by lead separation was determined to be optimal.In the experimental process,inhibitors YS02 and YS04 effectively suppressed galena,while the highly selective collector BS09 yielded copper concentrates with qualified lead grades.Ultimately,under the conditions of a grinding fineness of -0.074 mm accounting for 65 %,a copper separation process of once roughing and three times scavenging,and a lead separation process of once roughing,three times scavenging,and three times cleaning,the experiment achieved a copper grade of 24.63 % and a copper recovery rate of 81.05 % for copper concentrates,as well as a lead grade of 45.59 % and a lead recovery rate of 81.32 % for lead concentrates.The experimental indicators are considered ideal.
