Abstract

L'invention concerne un procédé d'obtention d'alumine pure par l'attaque sulfurique de minerais alumineux contenant des impuretés, suivie d'un traitement sulfochlorhydrique du produit résultant de l'attaque, de la précipitation d'un chlorosulfate d'aluminium hydraté, puis de sa transformation par pyrohydrolyse en sulfates d'aluminium hydratés ultérieurement décomposés par chauffage en alumine pure recherchée. Le procédé s'applique au traitement des matières alumineuses naturelles ou artificielles contenant des impuretés, tels que les minerais silicoalumineux, comme les kaolins, les bauxites siliceuses, les argiles kaoliniques, les schistes houillers ou non, ou bien encore des alumines ou sulfates d'aluminium impurs provenant de procédés primaires.
