Iron Ore Statistics and Information - USGS

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.

Simulation Modeling of an Iron Ore Operation to Enable ...

ore quality is to produce ore of consistent grade (not only in iron, but also in phosphorus, silica, and alumina). Traditionally this is achieved by blending from intermediate stockpiles, but this imposes large handling and stock costs which would be avoided if the desired grade uniformity can be achieved with less rehandling of the ore.
