Iron

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.

ILMENITE (Iron Titanium Oxide)

There is at least a small percentage of titanium in many many silicate and oxide minerals as titanium is actually quite a common element (9th most abundant in the Earth's crust). Of all of these minerals, only rutile, with a formula of TiO 2, competes with ilmenite for dominance in the titanium source department.

How Is Iron Extracted From the Earth?

How Is Iron Extracted From the Earth? Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace
