اقرأ أكثرMagnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron (II) and iron (III). Its empirical formula is Fe 3 O 4, and it is often expressed as iron (II,III) oxide. In the past, it has been called ferrous–ferric oxide and triiron tetraoxide. Magnetite is found in igneous, metamorphic, and sedimentary rocks.

اقرأ أكثرMagnetite and hematite are two forms of iron ores from which iron can be extracted. Magnetite contains iron in the form of Fe3O4. Hematite contains iron in the form of Fe2O3. The main difference between magnetite and hematite is that magnetite is ferromagnetic whereas hematite is paramagnetic. Are you minerals attracted to magnet?
