ABSTRACT OF THE DISCLOSURE Molten crude iron is made with simultaneous recovery of flue gases adapted for use in the prereduction of the ore from which the iron is obtained by following these steps a carbon precursor is introduced together with a gaseous reactive medium into a first zone of a main reaction chamber, the introduction being effected beneath the surface of a bath formed by the molten ore or iron so as to cause the carbon to combine with the iron and to supersaturate the melt with carbon; oxygen is simultaneously blown into an adjoining second zone, acting as combustion zone, of the main reaction cham- ber and below the surface of the bath while the bath is continuous- ly agitated so as to convert the excess carbon introduced in the first zone to carbon monoxide, the ore continuing to be melted by the thus produced exothermic reaction in the second zone; the flue gases generated in the main reaction chamber are recycled into a reduction chamber so as to subject the ore to an at least partial prereduction; the ore is passed from said prereduction chamber in- to the second zone of the main reaction chamber at a point close to the point where the oxygen is blown into the bath, and the form- ed molten crude iron is withdrawn from the bath. - 1 -
