| 摘 要： | 对四川某难选多金属硫化矿，在铜锌分离时加入硫化钠超前测沉淀铜离子。利用T-207作铜捕收剂。使铜精矿在回收率基本不变的情况下，品位提高了1．53％。铜精矿中锌含量由13．39降至5．62％；采用T-2000与石灰组合抑硫．使锌精矿品位由42．78％提高至49．02％。锌回收率提高了16．08％，一举解决了生产中铜锌硫分离难的老问题．为矿山增加效益提供了一条快捷简便、科技含量高的可行途径。

| Abstract: | To separate copper from zinc in the minerals with vulcanized metals of Sichuan, NaeS is joined to precipitate copper ion before using T- 207as selective agent for separating copper. The percent recovery of copper concentrate is constant, but the purity of concentrate increase 1.53 % and the purity of zinc in the copper concentrate decrease from 13.39 % t05.62 % ,The purity of zinc concentrate increase from 42.78 % to 49.02% and the precent recovery of copper concentrate increase 16.08% when using T-2000 and lime to inhibite sulphu. The method solved the puzzle of separating copper from zinc it is a simple and high tech- nological path to increas the benefit of the company. |
