One of the ores from which alumina is extracted and from which aluminum is eventually smelted Bauxite usually contains at least 45 percent aluminum oxide (alumina), and the best grades have a low silica content About four pounds of bauxite is required to produce one pound of aluminum

Bauxite is a clay-like substance from which aluminium is obtained. a soft substance that aluminium is obtained from (Les Baux, place in southern France where it was found). Most important aluminum ore, of varying compositions in which aluminum hydroxide or aluminum oxide predominate (named for Les Baux in southern France, where the ore was identified in 1821). The other constituents are largely iron oxide, silica, and titania. Bauxite has been found in all the continents except Antarctica. Known deposits can supply the world with aluminum for hundreds of years at present production levels
