Bauxite: Mineral information, data and localities.
Bauxite (Aluminium) Colour: Shades of brown, red-brown, and yellow-brown. Name: After the locality at Baux (or Beaux), near St. Reny, Bouches-du-Rhône, France. Predominantly hydrated aluminium oxides with iron oxides, kaolinite and other impurities; almost always a residual soil rather than a sediment. Note that iron-rich sediments are covered elsewhere. A mixture, and rock, comprised of iron ...

How Aluminum Is Made | Metal Supermarkets - .
90% of all mined bauxite is made into alumina to be smelted into aluminum. The remaining 10% is used for other purposes including the manufacture of abrasives, furnace linings, and proppants for the oil industry. It takes 4 tons of high-quality bauxite to produce 2 tons of alumina, from which 1 ton of aluminum can be made.

Alumina Production in Russia Part I - Welcome .
In 1933, development of the bauxite mines near Nadejdinsk (currently known as the Northern Ural bauxite mines) was initiated, as was construction of the Ural aluminum complex. This complex was built near Kamensk-Ural because of the nearby bauxite and coal reserves. The project stipulated construction of an accompanying 70,000 t/y alumina facility that would employ the Bayer method to treat the ...

Negative Impact Of The Bauxite Mining Industry ...
Bauxite mining, which is considered as surface mining, is land extensive, noisy and dusty. Mining pits are often interspersed within small rural communities, therefore requiring companies to relocate the people and or to monetarily compensate them. An increasing concern is the loss of habitat for Jamaica's unique plant and animal species; also bauxite mining severely affects the water ...

Bauxite (Saline County) - Encyclopedia of Arkansas
The story of Bauxite (Saline County) is largely the story of the bauxite mining industry. Bauxite, the ore from which the town derives its name, and which is a key component in the production of aluminum, was discovered in great abundance in this area of central Arkansas in 1887. The company that became Alcoa, which mined the ore, not only provided plants and mills but also provided a ...
