Abstract

L'invention concerne des procédés efficaces de lixiviation de minéraux à partir de minerais au moyen d'une solution acide, telle que l'acide sulfurique. Parmi les facteurs additionnels pouvant améliorer la récupération de minéraux, on trouve l'utilisation d'un halogénure de métal alcalin, le broyage des minérais, l'addition d'une source de carbone et/ou le réglage de la température à laquelle le procédé est mis en oeuvre. Des minéraux, tels que le titane, le fer, le nickel, le cobalt, l'argent et l'or peuvent être récupérés selon les procédés de cette invention.
