The Corex process, 24 commercialized by Voest Alpine, combines an iron melter/coal gasifier vessel with a prereduction shaft to produce a liquid product that is very similar to blast furnace hot metal. Coal, oxygen, and prereduced iron are fed into the melter/gasifier to melt the iron and produce a highly reducing offgas.
