  • Magnetite

    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

    4. Conclusion. Loss of valuable minerals during the concentration of ultrafine magnetite particles have been reported to be significant. Such losses are expected to increase in tonnage in the future as the need to treat lower grade magnetite ores increase and/or as the iron making industries demand cleaner concentrates both requiring finer grinds.
