西藏某多金属矿选厂的铜钼混合精矿-0．048 mm含量为85%,铜、钼品位分别为19．06%和0．640%,金、银含量分别为6．98和490．90 g/t,99%以上的铜钼矿物为原生或次生硫化矿物。采用高效易降解药剂对该混合精矿进行铜钼分离选矿试验,结果表明,在磨矿细度为-0．048 mm占90%的情况下,以高效易降解的ZG-2为铜矿物抑制剂、HTL-3为钼捕收剂,采用1粗4精2扫、中矿顺序返回的闭路流程分离试样中的铜钼,最终可获得钼品位为47．68%、钼回收率为81．45%的钼精矿,和铜品位为19．26%、铜回收率为99．94%的铜精矿,金、银主要富集在铜精矿中,实现了该铜钼混合精矿的高效、低毒分离。

Particles of a copper-molybdenum rough concentrate from a polymetallic plant in Tibet is -0. 048 mm 85%. Copper,molybdenum,gold and silver grade is 19. 06%,0. 640%,6. 98 g/t,and 490. 90 g/t,respectively. Over 99% of the copper and molybdenum are native or secondary sulfide minerals. Beneficiation experiments were conducted on the ore in order to separate molybdenum from copper on the mixed concentrate using highly efficient and easy to be degraded reagent. The re-sults indicated that:molybdenum concentrate with molybdenum grade of 47. 68% and recovery of 81. 45%,and copper concen-trate with copper grade of 19. 26% and recovery of 99. 94% was obtained by the process of one roughing-four cleaning-two scavenging and middlings back to the flow-sheet in turn with high efficient and easy to be degraded ZG-2 as copper depressor, HTL-3 as copper collector at the grinding fineness of 0. 048 mm passing 90%. Gold and silver mainly were enriched in copper concentrate. High efficiency and low toxicity separation of the copper-molybdenum bulk concentrate can be achieved.
