Corex(R)
COREX is a coal based smelting process that yields hot metal or pig iron. The output can be used by integrated mills or EAF mills. HOWThe process gasifies non coking coal in a smelting reactor, which also produces liquid iron. The gasified coal is fed into a shaft furnace, where it removes oxygen from iron ore lumps, pellets or sinter; the reduced iron is then fed to the smelting reactor.
