Abstract: 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%.The experimental results demonstrate that it is effective to recovery zinc and manganese from zinc-electrowinning anode mud by washing and reduction leaching process.
