Preparation of DRI from Waste Iron Ore and Coal fines

Abstract

In 2011 the world crude steel production reached 1527 million tons (MT) and showed a growth of 6.8% over 2010. China remained the world‘s largest crude steel producer in 2011 (695.5 MT) followed by Japan (107.6 MT) and the USA (86.2 MT). India occupied the 4th position (72.2 MT) for the second consecutive year. The WSA has projected that apparent steel use will increase by 6.5% to 1,398 MT in 2011, following growth of 15.1% in 2010. In 2012, it has been projected that the same will grow further by 5.4%. Such growth will be largely driven by China and India with China‘s apparent steel use in 2011 and 2012 expected to increase by 7.5% and 6% respectively. For India, growth in apparent steel use is expected to be subdued at 4.3% in 2011 but expected to go up by 7.9% in 2012. Per capita finished steel consumption is estimated to be 206 kg for world whereas 427 kg for China
