Title:
亜鉛の分離及び回収の為の塩化物溶融方法
Document Type and Number:
Japanese Patent JP4427686
Kind Code:

Abstract:
Process for the production of ZnCl2 from a Zn bearing primary and/or secondary material comprising the steps of reacting the Zn bearing material with a chlorinating agent such as Cl2 to convert metals into chlorides and vaporising the volatile components of the reaction product at a temperature between the melting point of said reaction product and the boiling point of ZnCl2, thereby recovering a Zn rich chlorinated melt, and thereafter distilling ZnCl2 from this Zn rich chlorinated melt, thereby recovering purified ZnCl2 and a Zn-depleted chlorinated melt.
