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) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.
It is also the world's third-largest producer of LNG and is forecast to be the world leader by 2020. Reduction of iron ore to reduced iron form adds value and provides more compact products, which reduces shipping costs. The specific iron content of the direct reduced iron is a function of the iron content of the iron ore.
