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.
