Mining and Refining – Process
Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to bauxite mines and/or ports for efficient transport of raw materials and of the final product.

TENORM: Bauxite and Alumina Production Wastes | …
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. Finally, hydrated alumina is crystallized and calcinated (dried in a furnace) to produce solid alumina.
bauxite processing alumina - Honden in de Meent
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.

Today’s alumina and bauxite producer is constantly challenged to improve safety, profitability, efficiency, and product quality while helping to sustain the surrounding environmental resources. Water plays a critical role in virtually all mining and mineral processing activities.
bauxite ore mining and processing - galerieagnes.nl
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.
