A process of producing aluminium and aluminium-containing materials from a solid aluminium-containing feed material is disclosed. The process comprises leaching the aluminium-containing feed material with a leach liquor and forming an aqueous solution containing aluminium ions, extracting aluminium ions from the aqueous solution by contacting the aqueous solution with an organic reagent and loading aluminium ions onto the organic reagent and forming an aluminium complex, and recovering aluminium or an aluminium- containing material from the aluminium complex.
L'invention concerne un procédé de production d'aluminium et de matériaux renfermant de l'aluminium à partir d'une charge solide contenant de l'aluminium: lixiviation de cette charge avec une liqueur lixiviante et formation d'une solution aqueuse renfermant des ions d'aluminium, extraction des ions à partir de la solution par contact avec un réactif organique et chargement des ions sur le réactif puis formation d'un complexe d'aluminium, et enfin récupération de l'aluminium ou d'un matériau contenant de l'aluminium à partir du complexe.
