the american mineralogist, vol, 55, may-june, 1970 chemical composition and physical prop-erties of magnetite from the ejected plutonic blocks of the,What Are the Uses of Magnetite? | Reference,The magnetite can be reused in this process 90 percent of the time. Magnetite is also used as a source of iron to manufacture iron-based chemicals and fertilizers. Ferric chloride and ferric sulphate are manufactured with magnetite as one of the starting materials. These chemicals are effective in clarifying raw water in water purificationDetermination of nanoparticulate magnetite stoichiometry,,Magnetite can have a range of oxidation states dependent upon the amount of structural Fe2+, which can be discussed quantitatively as the magnetite stoichiometry (x = Fe2+/Fe3+). For magnetite with an ideal Fe2+ content (assuming the Fe 3 O 4 formula), the mineral phase is known as stoichiometric magnetite (x = 0.50).

Magnetite is the most magnetic of all the naturally occurring minerals on Earth.
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.
