how is manetite mined from the earth

  • Magnetite

    Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth.

    1 Answer. In magnetite, it is a combination of both ferric and ferrous: 2 4. Thus, whether it is magnetite or hematite that are stable is mostly determined by the oxidation state of iron.

    Full Answer. The formation of magnetite during the geological metamorphism of limestone only occurs with limestone that formed before oxygen levels on Earth were sufficient for dissolved iron to accumulate in the oceans. This iron reached levels where it clumped and solidified out of the ocean water, forming iron ores on the sea floor.
