Energy Saving Improvement and Practice of Volatilization Kiln Treatment for Zinc Leaching Residue
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.
