摘 要: 提出了一种处理含砷烟灰的方法,并用这种方法处理铜转炉烟灰。首先将砷一次性地彻底除去, 并以较纯的形态富集, 然后加工成砷酸铜, 砷回收率达99%。同时,铅、铋、锌等有价金属很好地得到分离、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.
