In the industrial production of zinc hydrometallurgy, zinc ash is the by-product of electrolytic cathode zinc sheet melting and impurity removal in zinc melting induction furnace. Zinc ash contains about 80% zinc, of which more than 70% zinc exists in elemental form. In this paper, the advantages and disadvantages of dry and wet treatment processes are compared, the key equipment selection and capacity calculation for the dry treatment process are mainly introduced, and combined with the actual production situation the process equipment is improved and perfected after production.
