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.

Iron ore concentrate is produced from the magnetite iron ore in the beneficiation process and is used for the production of pellets for blast furnaces and sinter. The concentrates are non-toxic, non-flammable and non-explosive. The concentrate is shipped as a bulk commodity by rail using the open-top rolling stock and by sea. Manufacturer: SevGOK.

3. Ore Dressing: In order to increase the iron content of an ore, it undergoes dressing to remove some of the waste component, called tailing. The efficiency of a dressing is assessed either by a concentrate (remaining valuable portion) yield, or by the degree of iron extraction. The concentrate yield is = (O- T)/ (C-T) * 100%
