摘 要: 提出了一種處理含砷煙灰的方法，并用這種方法處理銅轉(zhuǎn)爐煙灰。首先將砷一次性地徹底除去， 并以較純的形態(tài)富集， 然后加工成砷酸銅， 砷回收率達(dá)99%。同時(shí)，鉛、鉍、鋅等有價(jià)金屬很好地得到分離、回收，回收率高。

Abstract:A new process for treating bearing arsenic dusts was described. The result of treating copper convertor's dust with this process was perfect. Initially the arsenic in convertor's dust was removed almost completely and concentrated in a relatively pure form, and subsequently copper and arsenic combined to form copper arsenate. The overall recovery of arsenic was about 99%. The main valuable metals, such as lead, tin, bismuth and zinc are separated each other with high recoveries.
Key words: arsenic convertor's dust copper arsenate
