How to Recover Iron from Magnetite: 4 Methods and Stages
Magnetite is an iron oxide ore, which belongs to the equiaxed crystal system, and its chemical formula is Fe3O4. The Mohs hardness of magnetite is 5.5~6.5. Like hematite, it has strong magnetism. In ancient times, it was also called a magnet. Magnetite is often formed in igneous, metamorphic, or granitic pegmatites, high-t…

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.
