Iron Ore Statistics and Information - usgs.gov

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.

Thus, the total specific energy for concentrating iron ore at the average ore grade (∼ 50% iron) from Thanatia (3.63% iron) was considered as the sum of the energy for the ore-handling process and the energy for concentration. In our model, the minerals for concentration are obtained from Earth's crust; surface mining is assumed.
