WEBApr 3, 2007 · Commercial magnetite often contains significant amounts of α and γFe 2 O 3, in addition to magnetite. As αFe 2 O 3 is nonmagnetic, it is not removed in the magnetic separator and is discharged in the refuse. It is believed that this is the cause for much of the loss of heavy media experienced in the coal cleaning plants.
