Abstract
La présente invention concerne un système et un procédé de traitement à sec de fines et superfines du minerai oxyde de fer présent dans les barrages de rejets et les minerais rejetés pauvres, comprenant un dispositif de séchage (9) à injection d'air chaud avec moyens d'agitation mécanique et axes pourvus d'aubes (9.2) pour la désagrégation et la mise en mouvement de la matière dans les directions horizontale et verticale, un ensemble de classificateurs pneumatiques raccordé fonctionnel à la sortie du dispositif de séchage, exécutant une classification des minerais de fer fins et superfins dans des plages granulométriques prédéterminées, et des séparateurs magnétiques (13, 16, 19) à rouleaux magnétiques (32, 42, 47) disposés en cascade, formés par des aimants de terres rares à faible et/ou haute intensité magnétique, les rouleaux magnétiques étant disposés selon un angle d'inclinaison déterminé.
