In view of the problems existing in the copper and sulfur separation process of a certain concentrator, such as high copper grade (>0.19%), large circulation load and low copper-sulfur separation efficiency of the tailings, operation process of one-roughing, three-scavenging and two-cleaning for cleaning stage of copper-sulfur separation was formed. Investigation of current status of the on-site process flow and mineralogy analysis of intermediate products in cleaning stage were conducted. On-site process optimization industrial tests were executed based on small-scale experiments on intermediate product grinding. Industrial test results of process flow transformation showed that the copper grade of tailings in cleaning stage dropped from 0.19% to 0.156%; the copper recovery rate in cleaning stage increased from 98.04% to 98.56%. The proposed process technological transformation can create economic benefits of about 16 million yuan per year.

针对某选矿厂铜硫分离工艺中存在的精选段尾矿铜品位偏高（>0.19%）、循环负荷大及铜硫分选效率低等问题，通过对现场工艺流程及精选段中间产品工艺矿物学进行系统分析，并结合中间产品磨矿小型试验及工艺流程优化工业试验，对原流程进行改造，最终形成了“一粗、三扫、两精”的铜硫分离精选段作业流程。工艺流程改造后，工业试验效果良好。与改造前相比，精选段尾矿铜品位由0.19%降至0.156%，精选段铜回收率由98.04%提升至98.56%，每年可创造经济效益约1600万元。
