Abstract
Procédé de raffinage d'une solution d'acide contenant des ions ferreux à laquelle on ajoute un métal (5) choisi dans le groupe comprenant Al, Cr, V, B, et Zn ou une solution d'acide de ce métal (5), telle qu'une solution d'acide qui reste après le lavage de l'acier par un acide, le pH de la solution d'acide étant contrôlé dans la gamme de 3,5 à 6 par addition d'un liquide alcalin (10) à la solution d'acide, de manière à ce qu'un sel d'hydroxyde du métal ajouté soit obtenu dans la solution d'acide et que les impuretés dans la solution d'acide soient fixées par le sel d'hydroxyde obtenu.
