Abstract
Process for the reduction of an iron ore in a fluidized bed, characterized in that it comprises the countercurrent contact of said mineral with a reducing gas containing hydrogen and from 0 to 40% of carbon monoxide, based on the total of hydrogen and carbon monoxide, at a temperature of approximately 538 to 875ยบ C, said mineral consisting of particles of irregular size distribution and of the order of 4 to -325 meshes approximately, the removal of particles of 1/3 to 1/10 of the average size of particles of said fluid layer, the placement of a sufficient quantity of particles with a size of 1/3 to 1/10 of the average size of said fluidized particles in said layer to maintain the concentration of particles of said size in said one layer between 4 and 20% by weight approximately.
