Magnetite - American Chemical Society

Magnetite 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.
