Direct reduction of iron is the chemical removal (reduction) of oxygen from iron ore in its solid form. The iron used in the steelmaking process is currently chemically reduced from iron ore through the use of fossil resources – natural gas or coal. This process is known as Direct Reduced Ironmaking (DRI).
