Noun1.bauxite- a clay-like mineral; the chief ore of aluminum; composed of aluminum oxides and aluminum hydroxides; used as an abrasive and catalyst Al,aluminium,aluminum,atomic number 13- a silvery ductile metallic element found primarily in bauxite ...
A mineral hydrated form of aluminum hydroxide; the principal ore of aluminum. Definition A natural aggregate of aluminumbearing minerals, more or less impure, in which the aluminum occurs largely as hydrated oxides. It is usually formed by prolonged weathering of aluminous rocks. Contains 30–75%...

Bauxite ores are rocks made up of hydrates of aluminium oxides (20 - 80 %) like gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), combined with iron oxide as goethite (FeO(OH)) and hematite (Fe2O3), kaolinite (Al2Si2O5(OH)4) as the clay mineral and sm...

The colour of the residue is red due to the presence of oxidized iron (hematite mineral) with an average amount of 33 - 48% . It is estimated that, for each ton of Al2O3 produced, 2 to 4 tons of bauxite are required, and 1 to 2.5 tons of residue is generated, depending on the...
Almost all of the aluminum that has ever been produced has been made from bauxite. Many people are surprised to learn that bauxite is a rock and not a mineral.
Bauxite actually refers to the industrial use of bauxite, bauxite as the main mineral composed of ore. Bauxite is the best raw material for the production of metal aluminum, and it is also the most important application field, accounting for more than 90% of the total output of bauxite in ...
