Zinc Oxide Production Technology of Distillation Twice Based on Scrap Miscellaneous Zinc Materials

Abstract:

By using scrap miscellaneouszinc materialas raw materials, a new technology with the help of two distillationsby fire method to produce zinc oxide was invented.The scrap miscellaneous zinc materialshave complex sources, containing dust, stone, iron and steel parts and other impurities, and zinc content is more than 15% over a wide range. The presence of zinc is in the form of pure metallic state, alloy state and oxidation state.Distillation process has two steps, the primary for removing the principal impurities and the second for zinc oxide purification. With less investment, low cost, simple equipment, easy operation, environmental protection and other advantages, this method is fit for production of high-purity zinc oxide and can also be used for the production of nanoscale high purity zinc oxide.
