How Is Bauxite Formed? | Reference.com

Bauxite ore is formed when the surrounding soil or rock is dissolved by natural weathering processes until it forms a new type of rock that is usually rich in aluminum ore. Though both types are used for aluminum production, the most valuable type of bauxite ore is lateritic ore.

Mining and Refining – Process

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.

TENORM: Bauxite and Alumina Production Wastes | US EPA

The Bayer Process. The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.

Bauxite

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. Achievable extraction efficiencies critically depend on the original concentration in the feed bauxite.
