研究了采用水洗和还原浸出法从锌电积阳极泥中提取锌和锰，考察了洗涤温度、洗涤时间、洗涤方式及还原浸出时间、浸出温度、pH等对锌、锰回收率的影响。试验结果表明：洗锌过程中，温度对洗锌率影响较大；在液固体积质量比3∶1、温度80℃条件下，通过逆流洗涤，洗锌率达97％以上，渣中锌质量分数在0．07％～0．09％之间。用SO2作还原剂浸出锰，pH和SO2气体流量对锰浸出率影响不明显；60℃下，锰浸出率在99％以上。通过水洗和还原浸出，锌电积阳极泥中的锌和锰得到有效回收，且流程简单。

Washing of zinc and reduction leaching of manganese from zinc-electrowinning anode mud was investagated .The washing temperature ,washing time ,washing way and leaching time ,leaching temperature ,pH and other parameters on recovery of zinc and manganese are examined .The results show that in washing zinc process ,washing temperature affects obviously washing zinc rate .Under the conditions of the ratio between liquid volume and solid mass of 3∶1 ,the washing zinc rate is 97% .In leaching manganese process using SO2 as reducing agent ,effecting of pH and SO2 gas flow rate on the leaching rate of manganese is not obvious .Under the condition of leaching temperature of 60℃ , manganese leaching rate reaches 99% .T he experimental results demonstrate that it is effective to recovery zinc and manganese from zinc-electrowinning anode mud by washing and reduction leaching process .
