Magnetite To Hematite In Pelletizing

During pelletizing of magnetite ore a significant part of the required energy originates from the oxidation energy during transition from magnetite to hematite. During the sinter tests it became clear that an addition of magnetite concentrate strongly contributes to a decrease in coke breeze consumption offering a possibility for decreased CO 2

Four sections process the magnetite based ore and one section processes the hematite based ore. There is a small amount of magnetite in the hematite stream so before the processing of the hematite stream can progress the magnetite needs to be separated. This can be achieved by magnetic separators since the magnetite ore is strongly magnetic.
