摘要
针对该赋存于氧化矿中的自然银矿石,采用浮选方法进行回收。闭路试验采用-0.074 mm 60%的磨矿细度,以异戊基黄药为捕收剂。通过一粗三精四扫的工艺流程,成功获得了品位为5427 g/t,回收率81.91%的银精矿。该流程药剂种类少,便于简单,且满足了现场选矿指标的要求,为该资源的综合利用提供了参考依据。
The natural silver ores existing in oxide ores were recycled by flotation. Using isoamyl xanthate as the collector,closed-circuit test were carried out in the condition that the roughing grinding fineness was- 0. 074 mm60%. The silver concentrate was obtained by one three roughing three cleanering four scavenging,whose grade and recovery were 5427 g / t and 81. 91% respectively. With a few kinds of reagents and easy operation,this process could meet the requirements of dressing indicators at site and provide reference for the comprehensive utilization of this resource
