Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.
The remaining 2% of domestic iron ore was produced for nonsteel end uses. Seven openpit iron ore mines (each with associated concentration and pelletizing plants), and three iron metallic plants—one directreduced iron (DRI) plant and two hotbriquetted iron (HBI) plants— operated during the year to supply steelmaking raw materials.

"Iron ore concentration facilities depend on surface chemical interactions for many concentration operations; therefore, strict control of water chemistry is necessary. Most tap water is of insufficient quality for direct use within iron ore concentration plants," he notes.
Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue.
