Direct reduced iron - Wikipedia

Direct-reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore to iron by a reducing gas or elementary carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated.
