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.
Abstract
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.
