Abstract
Procédé de traitement d'une matière contenant de l'oxyde de fer par passage dans un four tubulaire rotatif incliné afin d'en éliminer le zinc et le plomb par volatilisation, cette matière étant chargée sous forme de pellets et mélangée à un agent réducteur à base de carbone, et une fraction de la matière défournée étant recyclée et mélangée à la matière brute avant pelletisation de celle-ci. Selon le procédé de l'invention, on broie la matière recyclée séparée de la matière défournée contenant du fer métallique et on la réduit à une taille inférieure au millimètre environ avant de la mélanger à la matière brute, et l'on sèche au moins partiellement les pellets à une température inférieure à 300 degrés C en présence d'oxygène. Application notamment à la récupération des sous-produits de l'industrie sidérurgique.A method of treating a material containing iron oxide by passing it through an inclined rotary tube furnace in order to remove zinc and lead therefrom by volatilization, this material being charged in the form of pellets and mixed with a reducing agent at carbon base, and a fraction of the discarded material being recycled and mixed with the raw material before pelletizing the latter. According to the process of the invention, the recycled material separated from the discharged material containing metallic iron is crushed and reduced to a size less than about a millimeter before mixing it with the raw material, and at least partially dried. the pellets at a temperature below 300 degrees C in the presence of oxygen. Application in particular to the recovery of by-products from the steel industry.
