Iron processing

The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; magnetite (Fe3O4), which is black; limonite or bog-iron ore (2Fe2O3·3H2O), which is brown; and siderite (FeCO3), which is pale brown. Hematite and magnetite are by far the most common types of ore.

Iron Ore Statistics and Information | U.S. Geological Survey

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
