  • Difference Between Magnetite and Hematite | Compare the

    Jan 28, 2012· Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. This is the key difference between magnetite and hematite. Moreover, magnetite has higher iron content than hematite; therefore, its quality is higher. Apart from that, in colours too, there is a difference between magnetite and hematite.
