| 摘 要： | 青海某锑金矿选矿厂采用"先锑后金"的优先浮选流程,因矿石氧化程度高,泥化现象严重,导致浮选金精矿品位及回收率很低。为了提高金的选矿回收率,对选锑尾矿采用CIL提金试验研究,金浸出率为65.10%,相比较原选矿工艺金回收率提高52.95%。

| Abstract: | Preferential flotation of antimony before gold is being used in a Sb-Au plant in Qinghai province.Because of high oxidation and severe argillation,gold concentrate grade and the recovery rate are very low.In order to enhance the recovery of gold,CIL gold extraction test is carried out on antimony flotation tailings,with gold leaching rate reaching 65.10%,52.95% higher than the gold recovery rate obtained by original mineral processing flowsheet. |
