Abstract
L'invention concerne un procédé de récupération de métal/métaux à partir d'un matériau contenant du fer riche en calcium (8), comprenant (a) la lixiviation (1) du calcium une ou plusieurs fois à partir dudit matériau contenant du fer riche en calcium (8) pour obtenir un matériau contenant du fer appauvri en calcium (13) ; et (b) la soumission du matériau contenant du fer appauvri en calcium (13) à un traitement pyrométallurgique (3) pour récupérer le métal/les métaux (17) à partir dudit matériau contenant du fer appauvri en calcium (13).
