An ore is a mineral deposit that contains a metal that can be extracted using existing technological methods. Iron can be extracted from two types of iron ores: Magnetite and hematite. Magnetite is composed of iron in the form of Fe 3 O 4. Hematite is a mineral that contains iron in the form of Fe 2 O 3.

magnetite, 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 veins.

Magnetite (also magnet iron, magnet iron stone, iron oxide, or iron (II, III) oxide) is the most stable iron oxide with high resistance to acids and alkalis. It has a cubic crystal system and a chemical molecular formula Fe3O4. One of the iron ions is divalent. The other two are trivalent, so Magnetite is also referred to as iron (II, III ...
