bauxite mineral performance

Bauxite (Aluminium): Mineral information, data and localities.

Bauxite is not a mineral, but rather a group of aluminum oxides. The term is generally used to describe the economically important mixture of these minerals, which form a mass of the individually classified members of Gibbsite, Boehmite, and Diaspore.Bauxite does not make aesthetic or interesting specimens as far as collectors are concerned, but it holds importance …

Bauxite mining in the United States

Bauxite is the primary source for aluminum (Al). Ores in this group include aluminum hydroxides, gibbsite, boehmite and diaspore. It is not just the concentration of aluminum that is important for bauxite mining, but also the identification of penalty elements such as iron oxide that may also make overall compositional analysis more challenging.
