Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of

Bauxite extraction levels were 140 million tonnes in 2002, therefore the metal production from primary ore was about 35 million tonnes in the same year. The consumption in Europe in 2002 was 10.2 tonnes, 35% of which came from recycled aluminum. The same figures also apply at a global level, where about one-third of the total requirement is obtained from recycling.

Bauxite is the principal ore of alumina (Al 2 O 3), which is used to produce aluminum (Al). It is composed of hydrated aluminum oxides, hydrated aluminosilicates, iron oxides, hydrated iron oxides, titanium oxide, and silica. It contains mixtures of various minerals such as gibbsite, boehmite, hematite, goethite, Al-goethite, anatase, rutile, ilmenite, kaolin, and quartz.

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world''s main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH) 4) and small

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.

Metallurgical bauxite is a low-value bulk ore, and therefore preference is often given to simple beneficiation techniques, such as crushing followed by dry screening or washing and scrubbing processes. The most effective way to remove both kaolinite and goethite is by washing, followed by attrition scrubbing and desliming through removal of clay-rich super fines in hydro-cyclone. Processing 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/or handleability. These deposits usually have a

The recently patented bauxite-based defluoridation method proposes the use of mildly processed (powdered) bauxite ore as a single-use dispersive batch media in a community-scale system [24]. Bauxite, a globally abundant ore of aluminum, is a viable, effective, and low-cost fluoride adsorbent alternative to AA.

Bauxite, the main ore for aluminium, is another bulk material that may contain trace but significant quantities of REE. Extraction of REE, including Sc, may be possible from bauxite as it is processed, or from red mud waste. Even though the concentrations of REE are low, given the large amounts of bauxite processed, production could be significant. A study of two red mud waste localities in

Bauxite beds are blasted loose and dug up with power shovel or dragline, and the ore is transported by truck, rail, or conveyor belt to a processing plant, where it is crushed for easier handling. Refining plants are located near mine sites, if possible, since transportation is a major item in bauxite costs.
