摘　　要：采用侧吹炉协同处理铜阳极泥浸出渣,综合回收有价金属,考察了纯碱用量、粒煤用量、沉淀时间、炉顶烟气温度对主金属Pb、Sb、Bi、Au、Ag回收率的影响。结果表明,适宜的处理工艺参数为:纯碱用量2.5%、粒煤用量3%、沉淀时间1.5 h、炉顶烟气温度750℃,此时贵铅中Au品位达到1 544 g/t(富集了1.84倍)、Ag品位达到10.37%(富集了1.4倍)、Pb品位达到22.89%(富集了2.1倍)、Bi品位达到27.45%(富集了2.2倍)。A side blowing furnace was adopted to treat the leaching residue of copper anode slime and recover valuable metals therein comprehensively.The effects of soda dosage,granular coal dosage,precipitation time and top flue gas temperature on the recovery rates of main metals Pb,Sb,Bi,Au and Ag were investigated.The results show that with soda at an amount of 2.5%,granular coal at an amount of 3%,the precipitation time of 1.5 h,and the top flue gas temperature of 750℃,the precious lead product is obtained after processing,grading 1544 g/t Au(1.84 times enrichment),10.37%Ag(1.4 times enrichment),22.89%Pb(2.1 times enrichment),and 27.45%Bi(2.2 times enrichment).
