Application of Ceramic Ball Combined with Tower Mill in Copper-sulfur Separation Process of Anhui Longqiao Mining Company
In order to further reduce the flotation production cost of the concentrator of Longqiao Min-ing Company,improve the concentrate overgrinding and the flotation index,in view of the high energy con-sumption and serious concentrate overgrinding of the copper-sulfur separation coarse concentrate regrinding machine in the concentrator,a new type of low-consumption tower mill is used to replace the original over-flow ball mill,and the nano-composite ceramic ball is used as the grinding medium.The industrial applica-tion practice shows that the recovery rate of copper operation is increased by 2.15 percentage points by using tower mill and ceramic ball grinding.At the same time of further reducing energy consumption,the over-grinding degree of concentrate is improved,the flotation process index is improved,and the comprehensive economic benefit is 96.8 million yuan per year.
