Abstract

L'invention concerne un procédé de préparation d'alumine. Le procédé comprend une étape consistant à lixivier un matériau contenant de l'aluminium (par exemple un déchet industriel choisi parmi la boue rouge, des cendres volantes et leur mélange) avec du HCl afin d'obtenir un lixiviat comprenant des ions aluminium et un solide, et séparer le solide du lixiviat. Le procédé comprend ensuite une étape consistant à faire réagir le lixiviat avec du HCl afin d'obtenir un liquide et un précipité comprenant les ions aluminium en tant que AlCl3, et à séparer le précipité du liquide. On fait ensuite réagir le précipité avec une base. Enfin, le procédé comprend une étape consistant à chauffer le précipité dans des conditions efficaces pour convertir celui-ci en Al2O3.
