七宝山铜铅锌多金属硫化矿浮选新工艺研究

Study on the New Flotation Technology for Cu-Pb-Zn Polymetallic Sulphide Ore in Qibaoshan

为了给江西七宝山铜铅锌多金属硫化矿选矿厂的进一步优化改造提供依据,以江西理工大学自主研发的LP-01和LP-11分别作铜矿物和铅矿物的捕收剂,以丁黄药作锌矿物的捕收剂,以硫酸锌+亚硫酸钠作铅锌矿物抑制剂,进行铜铅锌依次优先浮选试验,获得了铜品位为19.84%、铜回收率为60.25%的铜精矿,铅品位为72.34%、铅回收率为7 3.04%的铅精矿,锌品位为50.55%、锌回收率为88.46%的锌精矿,使铜铅锌得到了较好的回收。

In order to provide the basis for Cu-Pb-Zn polymetallic sulphide ore in Qibaoshan Jiangxi province further optimized renovation,the high-effective collector LP-01 was selected as Cu collector and LP-11 as Pb collector,which were self-developed by Jiangxi University of Science and Technology,and butyl xanthate for Zn,the mixed reagent of ZnSO4 and Na2SO3 as Pb and Zn depressor.A better separation index was obtained through the selective floatation test of Cu-Pb-Zn,Cu concentrate with Cu grade of 19.84% and recovery of 60.25%,Pb concentrate with Pb grade of 72.34% and recovery of 73.04% and Zn concentrate with Zn grade and recovery of 50.55% and 88.46% respectively.Each of Cu,Pb,Zn gets the successful recovery.
