IntroductionSponge Iron - an overview | ScienceDirect Topics,DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H,Sponge Iron - an overview | ScienceDirect Topics,Direct reduction iron or sponge iron is an old method for producing hydrogen (Milne et al., 2006; Peña et al., 2010; Biljetina and Tarman, 1981) that was replaced by more efficient and economic processes.Recently, the interest in sponge iron as a hydrogen production process has grown again, although the technology still has some major technical and economic challenges to overcome (Milne
