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