摘　　要：对江西某铜矿石（铜品位为０．５８９％），采用扫选精矿再磨后返回粗选作业的新工艺流程，与常规流程相比可提高铜精矿品位０．４１８％、提高铜回收率５．７７％，经济效益显著。The flowsheet of 'scaveging concentrate return roughing after regrinding'was adopted to a copper ore in Jiangxi Province which contains 0.589% Cu.Comparing with ordinary flowsheet,the new one could increase by 0.418% Cu in concentrate grade and 5.77% in recovery,and achieve remarkable benefits.
