Bauxite Bauxite is the most important aluminium ore. It consists largely of the minerals gibbsite Al(OH)3, boehmite γ-AlO(OH), and diaspore Processing Bauxite is strip mined (surface mining) because it is found at the surface, with little or no overburden.
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 .
Most bauxite mines produce Direct Shipping Ore (DSO) bauxite as they require no processing before being sent to a refinery. However, some bauxites require some form of screening (either wet or dry) to remove the fine grained material to improve the grade and ...

Alumina Partners of Jamaica (ALPART) has its bauxite mining and alumina processing plant located at Nain, St. Elizabeth, in the south of Jamaica. The company was first established in the early 1960s under the union of three companies (Anaconda, Kaiser ...
The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. 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. ...
The objective of this study was to test the suitability of greenwaste biochar to aid nitrogen (N) retention in rehabilitated bauxite-processing residue sand (BRS). Bauxite residue sand was collected from the Alcoa of Australia Pinjarra refinery. The pH of BRS was adjusted to values of 5, 7, 8 and 9 and subsequently amended with different rates (1, 5, 10 and 20 %, w/w) of greenwaste ...
Generally there is a layer of capstone that is removed to expose the bauxite ore which is extracted, broken up and transported to refineries for further processing. AWAC is the world's largest bauxite miner and is well positioned with long life mines.
