Abstract

L'invention concerne des boulettes de minerai améliorées qui permettent de réduire les coûts énergétiques du durcissement tout en obtenant des granules affinées de bonne qualité. Les granules précitées sont utilisées pour la réduction lors du processus de fabrication du fer. Une boulette de minerai de fer à couches comprend une partie noyau et une partie coquille qui entoure la partie noyau. La partie coquille contient un premier concentré d'oxyde de fer et est dépourvue d'additif de combustible interne. La partie coquille contient un second concentré d'oxyde de fer et au moins un additif de combustible interne qui est ajouté au concentré d'oxyde de fer.
