  • Magnetite Wikipedia

    Magnetite is a mineral and one of the main iron ores. With the chemical formula Fe3O4, it is one of the oxides of iron. Magnetite is ferrimagnetic; it is attracted to a magnet and can be magnetized . Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control oxygen fugacity.
