Process of obtaining high iron content products from fines of iron ore and biomass, and their products

Abstract

This invention refers to a process for obtaining a product of high iron content and high physical and metallurgical performance for use in reduction furnaces (blast furnaces, and direct reduction) and melting furnaces (smelters, melters, and electric furnaces), aiming at the sustainable production of iron and steel. The process consists of mixing iron ore fines with biomass, binders, nanomaterials, additives, and catalysts, and performing subsequent steps of comminution, agglomeration, heat 10 treatment, solid-solid separation, and coating.
