Environmental impact of iron ore mining Wikipedia

Most iron ore is produced from open pit mines. After the iron ore is out of the ground, it may be shipped to the iron and steel manufacturing plant. If the ore contains less than 60 percent iron, it is usually beneficiated to an iron ore concentrate typically containing greater than 60 percent iron.
