beach sand magnetite mining

Magnetite - WikipediaMagnetite is a rock mineral and one of the main iron ores. With the chemical formula Fe3O4, it is one of the oxides of iron. Magnetite 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.beach sand magnetite mining,(Fe3O4) Extracted from Beach Sand Obtained by . - AIP Publishingresults inform us that the mechanical alloying method is a very attractive technique to reduce the beach sand particle into nanometer scale.
