摘　　要：对某铜冶炼厂产出的熔炼炉渣进行了工艺矿物学研究和选矿试验研究。炉渣经一段磨矿(-0.043 mm占80%)和快速浮选得到一部分合格铜精矿和尾矿;次粗精矿经过再磨再选得到另外一部分合格铜精矿。闭路试验得到铜品位为29.78%,铜回收率为90.55%的混合铜精矿,同时尾矿含铜降至0.28%。实现了铜渣中铜的高效化利用。Process mineralogy research and mineral processing experiment research have been carried out for a copper smelting slag;After primary grinding(particle size80%-0043mm)and speed flotation have been carried out for the slag,a qualified copper concentrate can be obtained.By regrinding and reconcentration of unqualified rougher concentrate,another part of copper concentrate and final tailings are produced.In closed circuit test,the copper grade of mixed concentrate can reach29.78%with the recovery of9055%,and the tailings copper grade is down to028%.Efficient recovery of copper from the slag can be achieved by test work.
