Bauxite recognised as 'critical raw material'

2020-9-4  Bauxite recognised as 'critical raw material'. The inclusion of bauxite, the aluminium-rich ore that is used for primary aluminium production, on the European Commission’s Critical Raw Materials list recognises the strategic importance of the aluminium industry in supporting Europe’s transition to a green and digital economy.

Why is Guinea Bauxite Considered the Best in the World

2017-8-2  Guinea has the largest bauxite reserve in the world at more than 40 billion tons of bauxite reserve. The bauxite mining and export from Guinea is fast picking up with present export of about 28 MTPA and a plan to reach 66 MTPA by 2018. Bauxite occurs in the low lying plateaus of 100 m to 300 m above mean sea level and formed by the laterisation

Chapter 2. Production and Processing of Aluminum

1999-5-7  Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America, Australia, India, and Africa. Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH) 3 in lateric bauxite.

The geomicrobiology of bauxite deposits ScienceDirect

2010-10-1  Bauxite has also been an important target for studies of paleoweathering, paleosurfaces and related continental deposits (Bárdossy and Combes, 1999).As the relict of colloidal precipitates resulting from deep chemical weathering of silicates, bauxite itself experienced an evolution from open, strongly oxidized conditions to gradually enclosed, reduced environments.
