Magnetite - Wikipedia
Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 2+ Fe 3+ 2 O 4. It is one of the oxides of iron, and is ferrimagnetic; [6] it is attracted to a magnet and can be magnetized to become a permanent magnet itself.
Magnetite | Common Minerals
Magnetite is a black, opaque, magnetic mineral that leaves a black streak when rubbed across a hard rough surface. It is one of the most abundant metal oxides, and its crystal structure contains both the ferrous (Fe+2) and ferric (Fe+3) forms of iron ions.
