Environmental impact of iron ore mining -
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. This is done by separating the iron minerals from the valueless minerals, usually by
