Abstract

L'invention concerne un procédé permettant de séparer des matériaux contenant du sulfure à l'aide de peroxyde d'hydrogène. Selon l'invention, on désigne par "matériaux contenant du sulfure" des matériaux d'origine naturelle, tels que des minerais mono ou polysulfurés, ou des produits de techniques industrielles, tels que les résidus de l'exploitation minière ou de la production de métaux.
