Abstract

La présente invention concerne des méthodes d'extraction du manganèse fondées sur l'utilisation d'un réducteur carboné, applicables en métallurgie pour l'extraction du manganèse métallique de sa matière première. Selon le procédé proposé, la matière première est mélangée à un réducteur carboné, puis la charge est transformée en briquettes et portée à fusion, la matière première étant concassée avant le mélange jusqu'à ce que la taille particulaire moyenne corresponde à la formule: dc « 150 x 10-6 / 3X1 + 1,5 M¿u?/Mc, où dc représente la taille particulaire moyenne de la matière première à teneur en manganèse, Mu la masse du réducteur carboné contenu dans la charge et Mc la masse de matière première à teneur en manganèse contenue dans la charge. Le réducteur carboné est concassé jusqu'à ce que la taille particulaire moyenne obtenue corresponde à la formule: du « 1,3 x dc x Mu/Mc où du représente la taille particulaire moyenne du réducteur carboné. La fusion se fait dans un four par immersion de briquettes dans le bain fondu, la puissance du four et/ou l'aire de surface des briquettes dans le bain fondu étant déterminée selon la formule: 2,4 x 10?6¿ < Q/F < 5 x 106 où Q est la puissance donnée au four (en watts) et F l'aire de surface des briquettes dans le bain fondu (m2).
