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.

Direct Reduced Iron - Open Source Ecology

Direct-reduced iron (DRI) is a metallic material formed by the reduction (removal of oxygen) of iron oxide (iron ore) at temperatures below the melting point of iron. DRI is produced by the use of a reducing gas (mostly a mixture of hydrogen and carbon monoxide). The temperatures for this process are significantly lower than those in a blast furnace, and capital requirements are also lower.
