Abstract
L'invention concerne la récupération de métaux précieux par lixiviation au thiosulfate, un lixiviant thiosulfate étant généré in situ au moyen d'un soufre élémentaire généré à partir d'une oxydation partielle d'une alimentation sulfurique contenant des métaux précieux et/ou au moyen de réactifs provenant d'un effluent de traitement.
