摘　　要：针对湿法炼锌系统产出浸出渣含硫高,在挥发窑强还原性反应气氛中容易形成硫化物,带来后续氧化锌粉处理终渣含锌高的情况,在生产上通过沸腾炉降低焙砂含硫、挥发窑生产过程调整反应气氛,或者氧化锌粉湿法处理过程增加氧化剂,有效地解决了氧化锌粉硫化物高造成的终渣含锌高问题。Leaching residues generated from the zinc haydrometallurgy system has high sulfur content,the sulphide is easy to formed in strong reductive reaction atmosphere of volatilizing kiln,therefore the subsequent final residues of treated zinc oxide powder has high zinc content,sulfur content of roasting sand can be reduced through fluidized bed combustion boiler,the reaction atmosphere can be adjusted in the production process of volatilizing kiln,or the oxidizing agent can be generated more in the treatment process of zinc oxide powder,therefore,the high zinc content problem can be effectively resolved that caused by high sulphide content in zinc oxide powder.
