A method for the production of iron from an iron oxide-containing material includes contacting an iron oxide-containing material with a particle size distribution range with a .part.90 of less than 2mm, with a carbon-containing material with a particle size distribution range with a .part.90 of less than 6mm, in a commercial scale reactor at a temperature of between 900°C and 1200°C for a contact time sufficient to reduce the iron oxide to iron.
L'invention concerne un procédé pour la production de fer à partir d'une matière contenant de l'oxyde de fer. Ledit procédé comprend la mise en contact d'une matière contenant de l'oxyde de fer dotée d'une plage de distribution de la dimension des particules possédant .part.90 de moins de 2 mm, avec une matière contenant du carbone dotée d'une plage de distribution de la dimension des particules possédant un .part.90 de moins de 6 mm, dans un réacteur à échelle industrielle à une température située entre 900°C et 1200°C pendant un temps de contact suffisant pour réduire l'oxyde de fer en fer.
