Abstract

New continuous procedure for the reduction of iron minerals, characterized in that they are applied in a liquid state by means of reducing gases and which consists, in the course of a first stage, of bringing these molten minerals into contact with reducing gases in one or more reduction phases, in each of which the degree of oxidation of the mineral remains practically constant, in order to reduce this degree of oxidation to a value between 1 and 1.2; then, in the course of a second stage, in bringing the liquid minerals thus obtained into contact with reducing gases in one or more reaction phases, in order to transform those minerals into liquid iron, and in transferring the liquid iron thus obtained.
