Abstract

LA PRESENTE INVENTION EST RELATIVE A UN PROCEDE DE REDUCTION DE MATIERES CUPRIFERES EN CUIVRE ELEMENTAIRE. SUIVANT L'INVENTION, CE PROCEDE CONSISTE A INJECTER LES MATIERES CUPRIFERES SOUS UNE FORME SOLIDE FINEMENT DIVISEE DANS UN REACTEUR MAINTENU A UNE TEMPERATURE D'AU MOINS 1083C, ET A METTRE EN CONTACT INTIME LES MATIERES CUPRIFERES AVEC DE L'HYDROGENE SOUS DES CONDITIONS QUI CONDUISENT A UNE REACTION DE REDUCTION PRATIQUEMENT INSTANTANEE AFIN DE PRODUIRE DU CUIVRE ELEMENTAIRE LIQUIDE. LE PROCEDE DE LA PRESENTE INVENTION S'AVERE INTERESSANT DANS LA RECUPERATION DE CUIVRE ELEMENTAIRE A PARTIR DE DIFFERENTS SELS DE CUIVRE, NOTAMMENT DES OXYDES DE CUIVRE, DES CHLORURES DE CUIVRE ET DES OXYCHLORURES DE CUIVRE.
