| 英文摘要 | Copper anode slime is a precious secondary source for the recovery of silver. However, current recovery process are constrained by either sever pollution or high cost. To cover the drawbacks of current process, this research employed a novel strategy by using the manganese dioxide as the oxidant in acid solution, which avoided the generation of sulfur dioxide while high silver extraction rate was achieved. The effects of manganese dioxide, sulfur acid concentration, stirring speed, temperature and leaching time on silver extraction rate were investigated. The silver recovery reached to 91.68% under the conditions of 1.2 g manganese, 2.0 mol/L H2SO4, 300 rpm, 80oC and 6 h. 漏 IMPC 2018 - 29th International Mineral Processing Congress.
