CA 2621464

A method of winning a metal from its oxide ore by heating the ore in a partial vacuum or under an inert atmosphere in the presence of a reductant. The resulting product may be further reduced electrochemically to produce a purer metal. The ore is preferably a titanium oxide ore and the reductant carbon or graphite.

L'invention concerne un procédé pour produire un métal à partir du minerai oxydé de ce métal. Le procédé selon l'invention consiste à chauffer le minerai dans un vide partiel ou sous une atmosphère inerte en présence d'un réducteur. Il est possible de soumettre le produit obtenu à une réduction électrochimique supplémentaire pour produire un métal présentant un degré de pureté plus élevé.
