Abstract

Le procédé de l'invention consiste à traiter en une seule étape une matière première contenant de l'oxyde d'aluminium à l'aide d'un mélange de sels métalliques alcalins d'un acide sans oxygène contenant du fluor et d'un acide chlorhydrique dont les rapports respectivement sont de 5:1 à 1:7,5 parties en poids. On introduit le mélange des sels en une quantité comprise entre 40 et 85 % du poids total, et on exécute le traitement à une température comprise entre 850 et 1100 °C jusqu'à obtention d'une masse de réaction constituée de bains de fusion alcalins de fluorure-silicate et de chlorure-aluminate, non mélangés. On sépare le bain de fusion alcalin de chlorure-aluminate de la masse obtenue, on l'introduit dans le bain de fusion de chlorures de métaux alcalins et on soumet la masse obtenue à une électrolyse jusqu'à obtention du produit voulu. On peut utiliser l'invention dans les domaines de production et d'utilisation d'aluminium.
