Bauxite Used for Aluminum Production. Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.

Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process.
Alumina Extraction Problem. In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch.
Aluminum processing, preparation of the ore for use in various products. Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a density of 2.7 grams per cubic cm. The most abundant metallic element, it constitutes 8.1 percent of Earth's crust.

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.
Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin.
