Magnetite | mineral | Britannica

Magnetite, also called lodestone, or magnetic iron ore, iron oxide mineral (FeFe 2 O 4, or Fe 3 O 4) 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, and high-temperature sulfide

MAGNETITE (Iron Oxide)

Magnetite is the primary oxide of iron found in meteorites (and thus presumably in asteroids). Thermite is a mixture of powdered magnetite and powdered aluminum. When ignited, the aluminum fuel burns using the magnetite as an oxidizer, resulting in much heat, aluminum oxide (corundum), and molten iron.
