摘　　要：为提高阳极泥回收贵金属变现周期,某贵金属冶炼企业加压浸出工序采用低温通氧自热浸出工序代替高压氧浸,并对加压浸出渣中Pb、Bi进行开路,大幅提高了加压浸出工序的产能及除杂效率,同时对阳极泥浸出工序技术优化后的污染物排放情况及治理措施进行了论述,并分析了技术优化后可能造成的环境问题。In order to improve the realization period of precious metals recovered from anode mud,the pressure leaching process of a precious metal smelting enterprise adopts the low temperature oxygen self-heating leaching process instead of high pressure oxygen leaching,and opens the Pb and Bi in the pressure leaching slag,which greatly improves the productivity and impurity removal efficiency of the pressure leaching process.At the same time,the discharge of pollutants and the treatment measures after the technical optimization of anodic mud leaching process were discussed,and the environmental problems that might be caused by the technical optimization were analyzed.
