摘要
以再生铜电解过程中产生的高砷高锡铅阳极泥为原料,采用火法—湿法联合工艺,经水洗—脱砷—酸浸—蒸发结晶,在有效回收锡、铅、铜等有价金属的同时脱除砷。结果显示,砷的脱除率达到96.49%,锡、铅、铜、镍、锑的回收率分别为96.80%、99.32%、93.72%、94.15%、97.80%。
Valuable metals were recovered and arsenic was removed from high As,Sn and Pb bearing lead anode slime coming from electrolysis process of secondary copper recycle applying a combination process of thermometallurgy and hydrometallurgy,i.e.,water washing,As removal,acid leaching,and evaporation and crystallization.The results show that removal rate of As is 96.49%,and recovery rate of Sn,Pb,Cu,Ni and Sb is 96.80%,99.32%,93.72%,94.15% and 97.80%,respectively.
