Cyclical batch processes for halogenation, such as chlorination, of minerals in a fixed bed (12, 42, 62, 82) using a plurality of cycles which include the steps of at least partially evacuating the bed, charging the bed (12, 42, 62, 82) with reactant gas, maintaining the reactant gas in the bed (12, 42, 62, 82) for a predetermined time, and exhausting reaction products under vacuum. Also disclosed is the chlorination of spodumene in its beta crystalline form produced by calcining spodumene in its naturally occurring alpha crystalline form to preferentially extract lithium as lithium chloride.
L'invention concerne des procédés discontinus d'halogénation, par exemple de chloration de minerais, dans un lit fixe (12, 42, 62, 82), au moyen d'une pluralité de cycles consistant à évacuer au moins partiellement le lit, à charger le lit (12, 42, 62, 82) avec du gaz réactif, à maintenir le gaz réactif dans le lit (12, 42, 62, 82) sur une durée prédéterminée, et à expulser des produits de réaction sous vide. L'invention concerne également la chloration de spodumène dans sa forme bêta-cristalline produite par calcination de spodumène dans sa forme alpha-cristalline naturelle, afin d'extraire de préférence du lithium sous forme de chlorure de lithium.
