Magnetite definition is - a black isometric mineral of the spinel group that is an oxide of iron and an important iron ore.
Hematite is the most important ore of iron and it has been used by people as a pigment for at least 40,000 years. Learn about the uses and properties of the mineral hematite.
Magnetite ore is a ferromagnetic material, with the chemical formula Fe3O4, and is one of several types of iron oxide.It is a ubiquitous mineral in many parts of the world, including Australia, the USA, Canada, South Africa, Mozambique and many other countries across most of the world's continents.

Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007).
Magnetite: Magnetite, iron oxide mineral (FeFe2O4, or Fe3O4) that is the chief member of one of the series of the spinel (q.v.) group. Minerals in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites, stony meteorites,
