Abstract
Process for the reduction of metal oxides, characterized in that it comprises the contacting of metal oxides with a reducing gas including carbon monoxide, by virtue of which the metal oxides are reduced and the carbon monoxide is partially oxidized to CO2, the removal of said reducing gas at high temperatures of the reduction zone, the rapid cooling of the gas, the separation of CO2 from said gas, the compression of the gas and the rapid reheating of said gas and subsequent recirculation of the gas thus treated to said zone of reduction.
