Abstract

La presente invención se refiere a un procedimiento para la obtención de un producto de alto contenido de hierro, alto rendimiento físico y metalúrgico para su uso en hornos reductores (altos hornos y reducción directa) y fusión (smelters, melters y hornos eléctricos), con el objetivo de la producción sostenible de hierro y acero. El proceso consiste en mezclar mineral fino de hierro con biomasa, aglutinantes, nanomateriales, aditivos y catalizadores, y realizar los pasos posteriores de trituración, aglomeración, tratamiento térmico, separación sólido-sólido y coating.
