Abstract

L?invention concerne un procédé de fabrication d?une alimentation de grande qualité pour haut fourneau à partir d?ultrafines de minerai de fer de basse qualité, qui comprend le traitement d?ultrafines par dispersion sélective pour séparer les matériaux de gangue du matériau de fer déposé et le traitement du matériau de fer déposé par redispersion avec un dispersant non sélectif. Le matériau déposé dispersé est alors traité par floculation sélective avec de l?amidon modifié pour séparer du fer concentré pour une alimentation de haut fourneau et des résidus, en laissant les minéraux de gangue dans la phase dispersée. Le procédé de séparation des minéraux contenant du fer et des minéraux de gangue est réalisé en fonction des états de charge de surface à un pH particulier pendant la redispersion avec un dispersant non sélectif et par ségrégation des particules plus fines par un procédé d?hydrocyclone pour une meilleure floculation afin de produire le produit final qui contient 68 % de Fe, 1 % d?alumine et 1 % de silice.
