Beschreibung
Zusammenfassung:	The present invention relates to a method for producing high iron-content products with a high physical and metallurgical performance for use in reduction furnaces (high-temperature and direct reduction furnaces) and smelting furnaces (smelters, melters and electric furnaces), aimed at the sustainable production or iron and steel. The method consists in mixing iron ore fines with biomass, binders, nanomaterials, additives and catalysts, and in subsequent comminution, agglomeration, thermal treatment, solid-solid separation and coating steps. . 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 (Fundición, Fundidores 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 revestimiento.
