易门铜冶炼渣成分复杂，铜品位为1．83%，主要铜矿物为硫化铜，占总铜的94．54%。为高效回收其中的铜，进行了选矿试验研究。结果表明，在磨矿细度为-0．045 mm占90%的情况下，采用1粗3精2扫、中矿顺序返回浮选流程处理该试样，可获得铜品位为18．27%、含银76．20g/t、铜回收率为84．86%、银回收率为44．06%的铜精矿。试验确定的选矿工艺流程较简单，不仅对铜有较好的回收效果，而且综合回收了其中的银，是该试样中铜的理想回收工艺。

The composition of Yimen copper smelting slag was complex,with Cu grade of 1. 83%. Main copper minerals are copper sulfide,accounting for 94. 54% of total copper. In order to high efficiently recover copper,mineral processing tests were carried out. The results showed that,at the grinding fineness of the-0. 045 mm accounted for 90%,through the process of one roughing-three cleaning-two scavenging,copper concentrate with copper grade of 18. 27% and recovery of 84. 86%,and silver grade of 76. 20 g/t and recovery of 44. 06% was obtained separately. The beneficiation process selected is simple,which can better recover the copper,and comprehensively recover the silver. It is the ideal process for copper recovery from the sam-ple.
