Study of Temperature Profile in the Induration of Magnetite Iron Ore
Induration of magnetite ore pellet is an oxidation process. During the pelletisation process, magnetite phase changes to hematite phase as given in Eq. . This chemical reaction is highly exothermic and releases a good amount of energy [7, 8]. It reduces the total energy consumption in comparison with pelletisation of hematite ore.
