Abstract

L'invention concerne un procédé de production d'agglomérats de minerai de fer, qui comporte l'étape consistant à agglomérer des particules fines de minerai de fer en présence d'un système de liant, ce système comprenant un liant et un silicate de métal alcalin présent à raison de 0,0001 à 0,08 pour cent en poids du poids total de l'agglomérat de minerai de fer. Le système de liant est exempt de polymère synthétique et comprend de préférence de la carboxyméthylcellulose comme liant.
