Melt-reductive iron making method from iron ore

Abstract From the Canadian patent

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 (hereinafter 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 maintaining and improving the reaction efficiency by applying various controls to evolved gas which is utilized in the reaction.
