What is Iron Ore? Earth's most important iron ore deposits are found in sedimentary formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).These iron ores have been mined to produce almost every iron and steel object that we use today ...

At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called "pig iron.". Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. The steelmaker uses a system that bubbles oxygen through melting pig iron.
