摘要: 根据新疆某氰化后尾矿的矿物性质,进行了铜、锌优先分离浮选中抑制剂、活化剂、捕收剂等的选择与用量试验,以及开路全流程试验和闭路试验。试验结果表明:1粗1扫3精、中矿顺序返回的铜、锌依次优先浮选工艺,可较好地回收铜、锌以及少量的金、银。获得了铜品位16.88%、铜回收率79.70%、金回收率34.97%、银回收率33.07%的铜精矿和锌品位52.07%、锌回收率63.77%的锌精矿,实现了矿产资源的再次回收。

Abstract: Based on the mineral properties of a cyanide tailings in Xinjiang, test on choice and dosage of agent like inhibitor, activating agent, collector, etc in prior separation flotation of copper and zinc, opencircuit whole process and closedcircuit test were done. The result indicated: one roughing, one scavenging, three reconcentrate, priority in turn flotation technology of copper and zinc of middling sequence recurrence, could better recovered copper, zinc and quantities of gold and silver. Copper concentrate with copper grade 16.88% and recovery rate 79.70%,gold recovery rate 34.97%,silver recovery rate 33.07% and zinc concentrate with zinc grade 52.07% and recovery rate 63.77% were obtained, twice recovery of mineral resources were realized.
