  • Magnetite - Wikipedia

    Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.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. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...

  • Hematite - Wikipedia

    Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe 2 O 3), one of several iron oxides. It is the oldest known iron oxide mineral that has ever formed on Earth, and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.
