MINING. Bauxite consists of 45-60% aluminum oxide, 12-30% water, and various other impurities. Bauxite is typically mined in open-pits and either processed . The water in bauxite is taken out of the ore. This leaves a white powder that is called alumina which is another name for aluminum oxide. Alumina is made into aluminum.

Bauxite reserves are spread across the world. Large deposits include: Australia, Brazil, Guinea and Jamaica. Around 85% of all Bauxite mined from the Earth is used to produce aluminium metal, which goes on to be used for a huge variety of uses. The remaining 15% goes towards chemical and refractory materials, along with making aluminium compounds.

The bauxite formed a bed averaging 2 m thick. The bauxite is friable and reddish-brown, contains boulders of all sizes up to 12 m diameter of gabbro, which would hinder mining. The core of the boulders is fresh, with a thin skin of bauxite. The bauxite ranged from 45–53% A1 2 O 3 and contains 64–78 % gibbsite.

Bauxite deposits form close to the surface. Hence, all the mines in the world are open pit. About 8-14 tons of bauxite is needed to produce one ton of aluminum 1. So the ore of aluminum needs to be fairly rich in this metal to be worth mining. Aluminum is extracted solely from bauxite, but that does not mean that there are no alternatives.
