Mining of Crude Ore Iron ore is a mineral substance that, when heated in the presence of a reductant, yields metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4 —iron content percent), hematite (Fe 2 O 3 —iron content percent), and goethite (Fe 2 O 3 H 2
