铜硫分离浮选工艺优化与工业实践OA
Research and Industrial Practice on Optimization of Copper-sulfur Separation Process
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.
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.
