Bauxite contains 40-60% hydrated aluminium oxide mixed with silica and iron oxide. It is the latter that gives bauxite its characteristic red colour. The name "bauxite" comes from the village of Les Baux-de-Provence in Bouches-du-Rhône (France), where the mineralogist Pierre Berthier first analysed the ore in 1821.

La bauxite est un minéral de roche sédimentaire qui est la principale source d'aluminium. Il est formé par l'altération des roches riches en aluminium dans les régions tropicales et subtropicales. Le nom bauxite est dérivé du village français des Baux, où il a été découvert pour la première fois en 1821 par le géologue Pierre Berthier. La bauxite …
Contribution of BRAVO to the EIP Objectives. 1. Reduction of import dependency and the promotion of production and exports. From a total aluminium metal supply of 13.2 million tonnes in 2011, 35% is produced by European primary smelters, 30% is net-imported and 34% is recycled by European refiners and remelters.

Chemistry questions and answers. Aluminum is mined as the mineral bauxite, which consists primarily of Al2O3 (alumina). The aluminum can be refined by heating the bauxite to drive off the oxygen: How much aluminum is produced from 3050 kg of Al2O3? The oxygen produced in Part 1 is allowed to react with carbon to produce carbon monoxide.
La bauxite est une roche latéritique blanche, rouge ou grise, caractérisée par sa forte teneur en alumine Al 2 O 3 et en oxydes de fer.Cette roche constitue le principal minerai permettant la production d' aluminium.
