摘　　要：针对铜阳极泥中难处理的分锑富集物,提出了Na2S-NaOH联合法一步浸出,使Sb大部分被浸出。在Na_2S浓度为165 g/L、NaOH浓度为30 g/L、液固比为5∶1、温度为85℃、反应时间1.5 h的条件下,锑的浸出率达到96.13%、渣率为30.75%。其活化能(E)为47.86 kJ/mol,反应过程为化学反应控制。The article put forward Na2 S-NaOH combined method of one step leaching for the enrichment in hard processing copper anode mud. The method leaching the most Sb. Under these conditions ： the concentration of Na2S 165 g/L, the concentration of NaOH 30 g/L, the ratio of liquid to solid 5： 1, leaching temperature of 85 ℃, the reaction time of 1.5 h, the leaching rate of antimony reached 96. 13% , slag rate of 30.75%. The activation energy （E） is 47.86 kJ/mol, and the reaction process is controlled by the chemical reaction.
