Direct reduced iron: History & Applications

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas which contains carbon (produced from natural gas or coal) or hydrogen. When hydrogen is used as the reducing gas, no carbon dioxide is produced. Many ores are suitable for direct…
