Fourth most abundant element in the earth's crust (56,300 ppm). Ninth most abundant element in the universe. Used in steel and other alloys. Essential for humans. It is the chief constituent of hemoglobin which carries oxygen in blood vessels. Its oxides are used in magnetic tapes and disks. Obtained from iron ores. Pure metal produced in blast furnaces by layering limestone, coke and iron ore and forcing hot gasses into the bottom. This heats the coke red hot and the iron is reduced from its oxides and liquified where it flows to the bottom 01z4tnBbsL0 Iron
