sponge iron process: IRON ORE MGM IRON ORE
Jun 25, 2008· Iron ore consists of oxygen and iron atoms bonded together into molecules. To convert it to metallic iron it must be smelted or sent through a direct reduction process to remove the oxygen. Oxygeniron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen.
