摘要: 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。

Abstract: 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 sample.
