Cost Of Crushing Iron Ore In The Usa

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 (Fe) is mined in around 50 countries worldwide and used to make steel (buildings, cars, white goods etc.). Global economic growth is the primary factor that drives its supply and demand. When economies are growing, the need for steel in construction increases which drives the price up

Although the majority of current steel production is supported by iron ore sourced from high grade haemetite deposits, the long-term growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed
