Improving reducibility of iron ore pellets by optimization

induration. A study with calcium hydroxide in iron ore pellet [ 5] showed that with increase in calcium hydroxide, amount of FeO increased because secondary Fe 2 O 3 reacted with CaO forming ferrite which helped in decomposition of Fe 2 O 3 again to FeO. Thus, with increase in amount of calcium hydroxide, hematite phase decreases due to dissociation of higher
