    2021-11-9 · Iron Ores (Hematite and Magnetite) Iron is a metal from the periodic table’s first transition series and group 8. It is the most common element on Earth by mass, just ahead of oxygen (32.1 % and 30.1 %, respectively), forming much of the Earth’s outer and inner cores. It is the fourth most abundant element in the crust of the Earth.
