Description: Iron is a substance which when heated in the presence of a reductant, will yield metallic iron Fe. It consists of iron oxides, the primary forms of which are magnetite Fe 3 O 4 and hematite Fe 2 O 3.Iron is the source of primary iron for the worlds iron and steel industries.
The black layer is about 45 meters thick and consists of a 20-meter-thick bed and two lower grade subeconomic beds. The slightly folded layering is shown by the shapes of the various mine . benches. Lighter material in the background is waste that must be stripped to expose the bed this waste material is used as backfill in
