Corex is a smelting reduction process combining a melter gasifier with a reduction shaft. The process takes lump iron ore or pellets, non-coking coal, and oxygen as main inputs. . The main product, the hot metal can be further treated in either EAF or BOF or can be cast and sold as pig iron (US DOE, 2003).
