Corex Process Wikipedia

In a singlestage system the iron ore is both reduced and melted in the same container. Meanwhile, in a twostage process, like Corex, the ore is reduced in one shaft and melted and purified in another. Plants using the Corex process have been put use in areas such as South Africa, India, and China.
