Direct reduced iron Wikipedia

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.

Products Made from Iron Ore

Iron ore is a mineral substance heavily comprised of iron oxides, primarily hematite (Fe203) and magnetite (Fe304). While mostly unusable in its native form, when mixed with a reductant and heated it produces metallic iron (Fe).
