Abstract

L'INVENTION CONCERNE UN PROCEDE POUR LA REDUCTION SELECTIVE DE LAITIERS OXYDES A FAIBLE TENEUR EN COBALT. LE PROCEDE CONSISTE A VERSER LE LAITIER DANS UNE POCHE ET A INTRODUIRE DANS LE JET DE COULEE, UN REDUCTEUR SOLIDE DIVISE A UNE CADENCE CORRESPONDANT SENSIBLEMENT A LA STOECHIOMETRIE DE LA REDUCTION. APPLICATION A L'OBTENTION D'UN ALLIAGE FER-COBALT RICHE EN COBALT.
