The Direct Reduction of Iron

For magnetite to wüstite, the ratios are 0.6–0.7; for wüstite to iron 2.0–1.7. Thus, hematite can be reduced to metallic iron with a gas possessing a reductant to oxidant ((CO + H 2)/(CO 2 + H 2 O)) ratio of at least 2:1 [45]; in actual practice 10 or 12 to 1 is the most reducing composition present.

Direct Reduced Iron

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.
