A New Process for Recovering Valuable Metals from Leaching Residue of Copper Anode Slime by Side Blowing Furnace
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 1 544 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).
