Iron | Fe (Element) - PubChem

Iron is the cheapest and one of the most abundant of all metals, comprising nearly 5.6% of the earth's crust and nearly all of the earth's core. Iron is primarily obtained from the minerals hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). The minerals taconite, limonite (FeO (OH)·nH 2 O) and siderite (FeCO 3) are other important sources.
