Magnetite | Common Minerals

2022-1-5 · By far, the two most economically important iron ores are hematite and magnetite. Although hematite is more abundant than magnetite, magnetite has the higher iron content, so magnetite iron ore deposits are highly sought after. Economic magnetite deposits primarily occur in layered igneous rocks that formed from the slow cooling of magma, heavy ...
