The reasons for the success of Sponge Iron Industry in

Presently, coal based units produce ~90% of the total sponge iron in India. Moreover, India's crude steel production grew at a CAGR of 6.75% between 2006-16. The production of EAF steel as a share of total steel grew at a steady rate, from 57% (2006) to 68% (2012), thereafter, this declined to ~57% in the past four years, ending 2016.

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.
