摘　　要：某高硫铜锌混合粗精矿在铜锌分离过程中难以获得铜品位18%以上的铜精矿,为解决铜精矿品位偏低的问题,进行了艾萨磨再磨工艺与现场球磨+水力旋流器再磨分级工艺对比试验研究。试验结果表明:采用艾萨磨工艺,铜锌分离作业可获得铜品位20.52%、锌含量2.38%、铜回收率89.32%的铜精矿,与现场球磨再磨工艺相比,铜精矿品位提高了2.82个百分点,锌含量降低了1.17个百分点,铜回收率提高了3.98个百分点。It is difficult to obtain copper concentrate with copper grade of more than 18%in the pro⁃cess of copper-zinc separation from a high-sulfur copper-zinc mixed rough concentrate.In order to solve the problem of low copper concentrate grade,a comparative experimental study was carried out on the Aisha mill regrinding process and the on-site ball mill+hydrocyclone regrinding classification process.The exper⁃imental results show that the copper concentrate with copper grade of 20.52%,zinc content of 2.38%and copper recovery of 89.32%can be obtained by using the Aisha grinding process in the separation of copper and zinc.Compared with the on-site ball milling and regrinding process,the grade of copper concentrate in⁃creased by 2.82 percentage points,the zinc content decreased by 1.17 percentage points,and the copper re⁃covery rate increased by 3.98 percentage points.
