Iron ore. Iron is the fourth most abundant element in the Earth's crust, but economic concentrations are dominated by comparatively rare iron oxide forms; magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeOH), limonite (FeO(OH)nH 2 O) and siderite (FeCO 3). The mineralogy of iron ore impacts its commercial value and how it is processed.

Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content.

Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue.

World resources are estimated to exceed 230 billion tons of iron contained within greater than 800 billion tons of crude ore. Substitutes: The only source of primary iron is iron ore, used directly as direct-shipping ore or converted to briquettes, concentrates, DRI, iron nuggets, sinter, or pellets.
