Abstract

L'invention concerne un procédé pour traiter ou purifier un concentré de molybdène contenant également du cuivre, selon lequel on soumet le concentré de molybdène à une oxydation sous pression, en présence d'oxygène et d'une solution de dosage contenant du cuivre (par ex. CuSO¿4?) et un halogénure (par ex. CuCl¿2?), pour produire une solution d'oxydation sous pression contenant du cuivre et un résidu solide contenant du molybdène. Cette solution d'oxydation sous pression peut être combinée à la solution de dosage pour une seconde oxydation sous pression, dans laquelle un concentré de cuivre est traité pour en récupérer le cuivre.
