摘要

"PROCESSES FOR THE PRODUCTION OF ZNCL ~ 2 ~, FROM PRIMARY AND / OR SECONDARY MATERIALS CONTAINING ZN, AND FROM ZN METAL AND CL ~ 2 ~". A process for producing ZnCL ~ 2 ~ from Zn-containing primary and / or secondary material comprising the steps of reacting Zn-containing material with a chlorinating agent such as CL ~ 2 ~ to convert metals to chlorides and vaporize the volatile components of reaction product at a temperature between the melting point of said reaction product and the boiling point of ZnCL ~ 2 ~, thus recovering a chlorinated Zn rich fusion, and then distilling ZNCL ~ 2 ~ from this chlorinated Zn rich fusion thus recovering purified ZnCl-2 ~ and a chlorinated fusion depleted into Zn.
