  • Magnetite - Wikipedia

    Magnetite is a 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.

  • Difference Between Magnetite and Hematite | Definition ...

    Jan 31, 2018 · Magnetite is an iron ore where iron can be found in the form of Fe 3 O 4. Magnetite is ferromagnetic, which means, magnetite particles are attracted to an external magnetic field; magnetite particles can act like tiny magnets when magnetized. Magnetite is ferromagnetic since it has both Fe 2+ and Fe 3+ ions that have many unpaired electrons.

    Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron-oxide concretions, iron-oxide nodules, and ironstones are often mistaken for meteorites because they are heavy (dense) and their unusual (frequently bizarre!) shapes catch people’s attention. Hematite concretions form by precipitation of iron oxide from iron rich solutions.
