Abstract

Cette invention concerne un procédé de création d'un minerai de faible qualité valorisé comprenant la détermination du produit fini souhaité en fonction de la composition du minerai de qualité inférieure, du concentré ou des oxydes résiduaires. Le mélange de cette source de matières premières de qualité inférieure avec une matière et un flux carbonés (selon les besoins) en tenant compte de la réduction complète et de la carburation du métal à enlever peut être mis en œuvre de façon que le métal à enlever soit séparé d'un laitier fusible ayant de l'affinité pour d'autres métaux dans le minerai de faible qualité. La réduction carbothermique sélective et la fusion du mélange de matières premières génèrent un produit métallique et un laitier, et le laitier peut être porté à fusion pour le séparer du produit métallique. Ces étapes peuvent être répétées pour réduire sélectivement les métaux séquentiellement, et les transformer en produits à usage commercial.
