摘　　要：介绍了铜渣中铜和铁的赋存状态,分析了影响铜渣中铜、铁回收的主要因素。对某铜业公司冶炼炉渣采用浮选与磁选综合回收铜、铁的工艺流程进行了试验,并取得了较好的指标。在磨矿细度为-0.037 mm占95.27%,通过一粗二扫再精选闭路流程,获得了铜品位46.36%、回收率83.63%的铜精矿;通过二段磨矿加入分散剂,获得了铁品位51.81%、回收率为30.88%的铁精矿。The occurrence states of copper and iron in smelting copper slag are explained, the effect factors of copper and iron recovery from smelting copper slag are analyzed. Experiment was made on a technological process of flotation and magnetic separation to comprehensively recover copper and iron in the smelting slag from a copper company, and good separation indexes were achieved. By a closed circuit consisting of one roughing, two scavenging and re - concentration, at the grinding fineness of - 0. 037 mm fractions taking up 95.27%, a copper concentrate grading 46.36% at a recovery 83.63% was obtained. An iron concentrate grading 51.81% at a recovery of 30.88% was obtained by means of regrinding and adding dispersant.
