Effect of Magnetite on Mineral Phase Formation in

Effect of Magnetite on Mineral Phase Formation in

high grade magnetite ore by magnetic separation. Mean-while, in an oxidizing atmosphere, magnetite is oxidized into hematite. This reaction is an exothermic reaction, so that this reaction heat can be used in place of coke energy. Hence, as a result, the CO 2 emission can be also decreased. The reaction is shown below: 21Fe 34OO˜˚/.23 22 Fe OH
