Abstract

L'invention concerne un procédé de réduction de matériau d'oxyde métallique en métal consistant à réaliser une circulation forcée de matériau support fondu dans une boucle fermée comprenant à la suite une zone de réduction de charge sur un bras de la boucle, une combinaison de zone de désulfuration à l'état fondu et d'une zone de postcombustion ou de chauffage sur l'autre bras, à réduire l'oxyde métallique en métal solide grâce au matériau carboné contenu dans une charge composite mélangée d'oxyde métallique, de réducteur carboné et de fondant dans la zone de réduction, l'oxyde métallique et le réducteur carboné étant utilisés en proportions telles que le carbone du réducteur carboné est transformé en monoxyde de carbone, à faire réagir le monoxyde de carbone avec de l'oxygène en aval de la boucle d'affinage avant sa combustion complète dans la zone de chauffage à la surface du matériau support fondu de façon que la chaleur produite par la réaction soit transférée au matériau support fondu circulant vers la zone de réduction, à séparer un flottant métallisé du matériau support fondu par projection de ce fondant dans la première boucle d'affinage en vertu de la force de traînée exercée sur le fondant par le matériau support fondu avant que ce matériau ne circule vers la zone de chauffage de façon que la surface du matériau support fondu, dirigée vers la zone de chauffage, ne contienne sensiblement plus de matériau solide.
