Aluminum | Minerals Education Coalition

Many common minerals, including feldspars, contain aluminum, but extracting the metal from most minerals is very energy-intensive, and expensive. Therefore, bauxite is the primary source of the world's aluminum and it supplies 99% of metallic aluminum. It is also used in the production of synthetic corundum and aluminous refractories.

THORITE (Thorium Uranium Silicate)

THORITE (Thorium Uranium Silicate)

Thorite is the most common thorium mineral. Thorium is a highly radioactive element and could be used as a replacement for uranium in nuclear power generation. It is estimated to be three times as common as uranium and all the thorium in the Earth's crust could have more potential energy than both uranium and the fossil fuel reserves combined.
