Direct Reduced Iron Industry in India — Problems and

Less sponge iron fines generation — about 5-7% compared to 15-30% with lump ore. Therefore higher sales realization. vii. Higher strength of sponge iron produced. The high cost of beneficiation and pelletisiation plants can be shared by groups of coal based DRI producers as joint venture, as individual plant requirements are generallyMost iron is presently produced in the blast furnace (BF) using metallurgical coke. BF continues to be the main reactor for iron production because of its high productivity and thermal efficiency [].Despite several recent modifications, the BF requires a minimum amount of coke and produces around 1.8 tons of CO 2 per tonne of Review on Reduction Kinetics of Iron Ore–Coal Composite
