Abstract

La présente invention se rapporte à un procédé d'extraction d'ions d'aluminium à partir de minerais alumineux, tel que de l'argilite. Le procédé consiste à lixivier l'argilite avec un acide tel que le HCl de sorte à obtenir une composition comprenant des ions d'aluminium et des ions de fer; à éliminer au moins partiellement les ions de fer de la composition par précipitation sensiblement sélective des ions de fer à un pH d'environ 3 à environ 6 par ajout d'une base et par élimination au moins partielle des ions de fer précipités de sorte à obtenir une composition riche en Al; et, éventuellement, à purifier la composition riche en Al par ajout d'une base afin de précipiter de manière sensiblement sélective les ions d'aluminium au moyen d'une membrane en fibre creuse ou par extraction liquide-liquide.
