摘要
论述了采用通氧酸浸法分离黑铜中的铜砷，并制取硫酸铜和三氧化二砷的工艺方法，研究了各种工艺参数对铜砷分离的影响，试验结果铜、砷直收率分别为８７．１０％、６８．
An acid leaching process with introduction of oxygen is adopted for treating black copper produced during purification of copper electrolyte, and copper and arsenic thus obtained are used to make firstrate copper sulfate and arsenic white(As\-2O\-3 95%). Test and research about impact of various process parameters on separation of copper and arsenic are conducted. The direct recoveries of copper and arsenic by this process are 87\^10% and 68\^9% respectively.\=
