Abstract

Procedure to purify zirconium minerals by converting the accompanying foreign elements into chlorides and separating such chlorides; characterized by heating the ground zirconium mineral to 400-700ºC, by passing chlorinated hydrocarbon at that temperature, and separating the odorides formed from the reaction mixture, by means of distillation and/or washing.
