摘要/Abstract

摘要： 针对四川某铅锌银矿原选矿工艺不能适应矿石性质变化，而且在流程中使用氰化物的问题，对该矿矿石重新进行了浮选试验，结果表明：在-0.074 mm占85%的磨矿细度下，以石灰为调整剂、硫酸锌+亚硫酸钠为抑制剂、乙硫氮为捕收剂优先选铅，选铅尾矿以硫酸铜为活化剂、丁黄药为捕收剂选锌，可获得铅品位为51.80%、铅回收率为64.75%的铅精矿和锌品位为53.55%、锌回收率为91.83%的锌精矿，银在铅、锌精矿中的总回收率达到83.75%。试验不仅使铅、锌、银的回收率与现场工艺相比有明显提高，而且实现了铅锌无氰分离。

Abstract: Aimed at the problems that the former beneficiation process can not adapt the nature of the ore and cyanide addition in the process for a lead-zinc-silver mine in Sichuan, another flotation test on this ore was made.The results showed that: under the grinding fineness of -0.074 mm 85%, and with lime as adjusting agent, zinc sulfate+sodium sulfite as inhibitor, diethyldithioc butyl xanthate as collector to concentrate zinc, lead concentrate with grade of 51.80% and lead recovery of 64.75% and zinc concentrate with grade of 53.55% and recovery of 91.83% were obtained separately.The total recovery of silver in lead and zinc concentrates reached 83.75%.The tests realized higher recovery of lead, zinc and silver and adopted cyanide-free process, comparing with the on-site process.
