Bauxite
Bauxite. Bauxite contains typically 40–60% aluminium oxide (alumina) in the form of several hydrous alumina phases (gibbsite, Al (OH)3, boehmite (AlOOH) and diaspore (ALOOH), and with smaller amounts of iron, silicon and titanium compounds as well as other trace impurities. From: Fundamentals of Aluminium Metallurgy, 2011.
Bauxite Facts
It has a variable chemical composition but is always rich in aluminum oxides and hydroxides. These are most of the identifying properties for bauxite and are useful for identifying the mineral; however, bauxite is most often processed into another material with properties much different than bauxite. Interesting Bauxite Facts: Bauxite is the principal ore of aluminum and crushing it is the ...
Bauxite | Geoscience Australia
Bauxite is the main raw material used in the commercial production of alumina (Al 2 O 3) and aluminium metal globally, although some clays and other materials can also be utilised to produce alumina. Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium. The principal minerals in bauxite are gibbsite (Al 2 O 2 O), boehmite (Al ...

China's Aluminium Value Chain Quarterly Update is an independent and detailed assessment of the key metrics of China's bauxite, alumina and primary aluminium industries, as we see them, presented in the form of an easily digestible set of charts and tables, together with relevant commentary on significant events, emerging trends and other key themes arising from our analysis.
Aluminum | Minerals Eduion Coalition
Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral. Bauxite is reddishbrown, white, tan, and tanyellow. It is dull to earthy in luster and can look like clay or soil ...

Bauxite (Aluminium): Mineral information, data and localities. Bauxite is the main ore of aluminium (aluminum). It is composed primarily of impure aluminium hydroxides along with a lot of silica, iron and other impurities. It is usually formed as a weathering product of rocks rich in aluminium silies.

Bauxite mining in the United States
Bauxite forms by the weathering of aluminumrich and silicapoor rocks in hot, humid, climates, at places with good drainage. Under the proper conditions, weathering disintegrates the aluminium silie minerals, and dissolves and removes the silica, creating bauxite. The mined US bauxite deposits have all been in the southeastern United States.

Hence, bauxite is an aluminumrich laterite. The accumulation of aluminumrich residuum, as opposed to one enriched in iron, is a function of higher rainfall, but also lower average temperature (around 22 °C rather than 28 °C) 6. However, there are actually two types of bauxites. The genesis of only one of them can be adequately explained by the lateritization process. Lateritization usually ...
