Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe3O4.
It is a black or brownish-black mineral with a metallic luster and is magnetic in nature.
The mineral is found in igneous, metamorphic and sedimentary rocks.
Magnetite is a major source of iron and is used in the production of steel.
It is also used as a catalyst, abrasive, and as a magnetic coating for recording media.
Due to its magnetic properties, it is used in the manufacturing of various electronic components like speakers, hard disks, and magnetic resonance imaging machines (MRI).
Magnetite is also used in the production of heavy concrete and in the formation of dense aggregate for shielding structures from radiation.
It has a wide range of applications in the chemical industry and is used as a catalyst in various chemical reactions.
The largest deposits of magnetite are found in Australia, China, Russia, and the United States.
