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 chal-cocite 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 sup-pressed galena,while the highly selective collector BS09 yielded copper concentrates with qualified lead grades.Ulti-mately,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.
