<p>Process for the production of ZnCl<SUB>2 </SUB>from a Zn bearing primary and/or secondary material comprising the steps of reacting the Zn bearing material with a chlorinating agent such as Cl<SUB>2 </SUB>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 ZnCl<SUB>2</SUB>, thereby recovering a Zn rich chlorinated melt, and thereafter distilling ZnCl<SUB>2 </SUB>from this Zn rich chlorinated melt, thereby recovering purified ZnCl<SUB>2 </SUB>and a Zn-depleted chlorinated melt.</p> |
