Abstract

L'INVENTION CONCERNE UN PROCEDE DE REDUCTION SELECTIVE DE LAITIERS OXYDES A FAIBLE TENEUR EN COBALT. LE PROCEDE CONSISTE A BRASSER DES CHARGES SUCCESSIVES DE LAITIER FONDU AVEC UN BAIN METALLIQUE A BASE DE FER, ET EVENTUELLEMENT UN REDUCTEUR A BASE DE SILICIUM, A REJETER LE LAITIER EPUISE, ET A RECOMMENCER LE BRASSAGE AVEC UNE NOUVELLE CHARGE DE LAITIER FONDU, JUSQU'A OBTENTION DE LA QUANTITE D'ALLIAGE ET DE LA CONCENTRATION EN COBALT DESIREES. APPLICATION A L'EXTRACTION SELECTIVE DU COBALT SOUS UNE FORME DE FERROCOBALT.
