Effect of Mineralogy on Reduction Behaviour of Iron Ore

All iron ore pellets shows complete reduction at temperatures of 1173 and 1223 K within 120 minutes. The reduction results clearly show that the reducibility of the pellets depends on the initial mineralogy of the ore. It was also observed that the reducibility decreased as gangue content (Al 2 O 3 + SiO 2) increases. The activation energy of the pellets decreased from 46.54 and 49.13 kJ/mol when the …
