摘　　要：以硫化砷渣为原料,用氯化铜酸性溶液浸出砷渣的全湿法进行实验,着重研究氯化铜浸出砷的过程中氯化铜用量、溶液p H和浸出时间对砷浸出率的影响,探讨用氯化亚锡还原砷盐酸溶液从硫化砷渣得到单质砷的方法。In this experiment, arsenic sulfide residue was used as raw material and wet process of arsenic slag extraction with copper dichloride acid solution was applied. The research focused on the influences of the dose of copper dichloride, pH of the solution and leaching time on the leaching yield of arsenic during the leaching process with copper dichloride. Besides, the method of producing elemental arsenic from arsenic sulfide residue by reduction of arsenic acid solution with stannous chloride was also discussed.
