ABSTRACT OF THE DISCLOSURE A method of making iron by subjecting an iron oxide feedstock such as iron ore to a solid reduction with a reducing gas fed from a melt-reducing furnace (herein- after referred to sometimes merely as "melting furnace") and then supplying the feedstock to the melting furnace for melt reduction thereof. More particularly, it is concerned with a method capable of using a low grade fuel and main- taining and improving the reaction efficiency by applying various controls to evolved gas which is utilized in the reaction.
