Pure iron is not readily available since it easily oxidises in the presence of air and moisture. The iron industry reduces iron oxides to obtain pure iron, i.e. metallic iron. Steel is an alloy based on iron and carbon, with carbon concentration ranging from 0.2% to 2.14% in weight. High carbon content results in higher hardness, tensile

Direct Reduced Iron | Industrial Efficiency Technology ...

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.
