Magnetite and Magnetite Mining in Canada

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) oxide.
