      a) Fe3O

      b) Fe3H2O4

    • Black Iron Oxide / Magnetite Description:  

    a) Magnetite is a natural iron oxide magnet, hence the name, giving it a very nice distinguishing characteristic. Magnetite is the most magnetic of all the minerals on Earth.

    b) Magnetite is a member of the spinel group which has the standard formula A(B)2O4. The A and B represent different metal ions that occupy specific sites in the crystal structure. In the case of magnetite, Fe3O4, the A metal is Fe +2 and the B metal is Fe +3; two different metal ions in two specific sites. This arrangement causes a transfer of electrons between the different irons in a structured path or vector. This electric vector generates a magnetic field.

    c) Lustrous black, magnetic mineral, Fe3O4. It occurs in crystals of the cubic system, in masses, and as a loose sand. It is one of the important ores of iron (magnetic iron ore) and is a common constituent of igneous and metamorphic rocks. It is found in various parts of the United States, Norway, Sweden, and the Urals. A variety of magnetite, lodestone (or loadstone) exhibits polarity and is especially interesting for its natural magnetism; Magnet Cove, Ark. became famous as a source.

    d) Magnetite is sometimes found in large quantities in beach sand. Such mineral sands or iron sands or black sands are found in various places such as California and the west coast of New Zealand. The magnetite is carried to the beach via rivers from erosion and is concentrated via wave action and currents.
