Abstract
L'invention concerne un procédé d'au moins une opération permettant de régénérer des solutions acides métallifères issues d'un processus de traitement des surfaces. Ce procédé consiste a) à séparer les acides libres de la solution, ce qui permet d'obtenir un flux acide et un flux contenant un sel métallique et b) à régénérer le flux de traitement contenant un sel métallique.
