铜浮渣处理方法的研究进展

The Research Progress of Copper Dross Processing Method

铜浮渣是粗铅火法精炼时产生的副产物,含有铜、铅及贵金属等元素,如不对其处理,将造成二次资源的浪费,渣中的重金属也会对环境造成污染。本文介绍了国内外处理铜浮渣的生产工艺和研究进展,总结了各种方法的优缺点,认为采用真空冶金法处理铜浮渣将会有较好的应用前景。

Copper dross is the by-product from fire refining of lead bullion, which contains copper, lead and noble metal, etc. It shall cause secondary waste of resources and the heavy metal in the slag will also pollute the environment if it is not processed. The domes- tic and foreign production process and research progress of copper dross treatment is introduced in this paper, the advantages and disadvanta- ges of every method is summarized too, and the final conclusion is the vacuum metallurgical method has the better application prospect for copper dross treatment.
