Magnetite & Lodestone | Mineral Photos, Uses, Properties

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.


Iron (Fe) is the most abundant element, but it only comprises approximately 6 percent of continental crust. Metallic iron is silvery-white, malleable, ductile, and may be readily magnetized. Elemental iron has a relatively high specific gravity (7.87) and high melting point. Iron is used primarily in the manufacture of iron and steel products.

Iron ore - Wikipedia

Jan 12, 2020· Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
