Direct Reduced Iron

Direct Reduced Iron (DRI) is a process in which iron ore is reduced in a gas-based environment to produce sponge iron. The resulting material can then be melted in an electric arc furnace to make steel, making DRI a process stage connecting iron ore reduction with subsequent steelmaking. This archive covers DRI developments as part of lower-carbon ironmaking, including its relationship to hydrogen-based reduction and electric arc furnace production. DRI is a specific process route, whereas green steel is the wider emissions-reduction objective that may incorporate it.
