A Review on the Kinetics of Iron Ore Reduction by Hydrogen
A clean energy revolution is occurring across the world. As iron and steelmaking have a tremendous impact on the amount of CO2 emissions, there is an increasing attraction towards improving the green footprint of iron and steel production. Among reducing agents, hydrogen has shown a great potential to be replaced with fossil Iron ore granulation is significantly different from that in other fields due to the difference in nature of raw materials, particle size and facility scale. Powder Technology, Volume 396, Part B, 2022, pp. 663-672. Show abstract.
