Iron Mining Process | Equipment | Flow | Cases
Iron (element #26, symbol Fe) is the most common metallic element in the universe. When pure it is a dark, silvery-gray metal. It is a very reactive element and oxidizes (rusts) very easily. The reds, oranges and yellows seen in some soils and on rocks are probably iron oxides. Iron is the third most common element making up the Earth.
