摘　　要：为回收某硫化铜矿浮选尾矿中的有用矿物,提高资源利用率,采用"预先脱泥-浮选"的工艺流程进行了试验研究。结果表明,经预先脱除-0.02 mm粒级矿泥,在磨矿细度为-0.074 mm粒级占90%的条件下,以Lp-01+Y89为组合捕收剂,石灰为p H调整剂,水玻璃为抑制剂,最终实验室小型闭路试验可以获得含铜15.17%、铜回收率68.37%的铜精矿,实现了有用矿物的有效回收。A technique consisting of predesliming and flotation was adopted to reclaim valuable minerals from the flotation tailings of copper sulfide ore and improve the resource utilization. After a pre-discarding of slime with the grain size of -0.02 mm,a laboratory closed-circuit test was conducted with the grinding fineness of -0.074 mm 9 0 %, Lp-01 and Y 89 as a combined coflector, lime as pH regulator, and sodium silicate as depressant. As a result, a copper concentrate containing 15.17% Cu was obtained with recovery of 68.37%,showing an effective recovery of such copper resource.
