摘　　要：针对某品位低、深度氧化且含硅较高的复杂氧化铅矿,采用乙硫氮和新型药剂LW 13为捕收剂,分别浮选方铅矿和氧化铅矿物,在原矿铅品位为8.68%条件下,闭路试验获得了品位59.46%、回收率94.04%的铅精矿。Aiming at a low -grade complex lead oxide ore with deep oxidation and high content of silicon in Yunnan province, ethyl thio carbamate and new collector LW13 was used in flotation of galena and lead oxide ore respectively. Under the condition of the run - of - mine ore of 8.69% Pb, lead concentrate of 59.46% Pb with a recovery of 94.04% was obtained in closed circuit experiment.
