摘　　要：在湿法炼锌生产过程中,产出的锌浸出过滤渣中因含有较多的锌及其他有价元素(如Cu、Pb、Cd、In、Ge、Fe、As、Ag、Au等),将会进一步采取措施进行综合回收利用和无害化处理。利用挥发窑生产氧化锌过程的工艺原理及特点,提出电锌湿渣直接进窑进行生产来降低能耗和成本的方法,并对生产实践中的经验和效果进行分析和总结。In the production process of wet zinc smelting,the zinc leaching and filtration residue produced contains a large amount of zinc and other valuable elements(such as Cu,Pb,Cd,In,Ge,Fe,As,Ag,Au,etc.),and further measures will be taken for compre‐hensive recycling and harmless treatment.The process principle and characteristics of using volatilization kiln to produce zinc oxide are proposed,and a method of directly feeding zinc wet slag into the kiln for production to reduce energy consumption and costs is proposed.The experience and effects in production practice are analyzed and summarized.
