Bauxite - an overview | ScienceDirect Topics
Bauxite, the principal ore used for aluminum smelting, is named after Les Baux, Provence, the village where the first deposits were discovered. Bauxite contains hydrated alumina equivalent to as much as 40–60% Al 2 O 3, and is free of the other siliceous materials leached out over time. However it still contains 10–30% iron oxide, and some silica and other impurities, making it unsuitable for direct …
Bauxite - Wikipedia
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the worlds main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase and ilmenite. In 1821 the French geologist Pierre Berthier discovered …

Bauxite - ALS
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/or handleability. These deposits usually have a beneficiation plant that washes the bauxite and sends the high silica fines (kaolinite ...
Mining and Refining – Process - World Aluminium
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.
INTERNATIONAL ALUMINIUM INSTITUTE FOURTH SUSTAINABLE ...
Unlike other base metal ores, bauxite does not require complex processing, because most of the mined bauxite is of an acceptable grade or can be improved (beneficiated) by a relatively simple but not inexpensive process of removing clay. In many types of bauxite, clay is removed by some combination of washing, wet screening, cycloning and sorting.
