Mining and Refining – Process - World Aluminium

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 - Wikipedia

OverviewFormationProduction trendsProcessingSource of galliumSee alsoFurther readingExternal links

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 (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).

OverviewHistoryProduction and impactCommoditiesControversies and corruption in the mining industrySee alsoBibliography

The mining industry of Guinea was developed during colonial rule. The minerals extracted consisted of iron, gold, diamond, and bauxite. Guinea ranks first in the world in bauxite reserves and 6th in the extraction of high-grade bauxite, the aluminium ore. The mining industry and exports of mining products accounted for 17% of Guinea’s gross domestic product (GDP) in 2010. Mining accounts for over 50% of its exports. The country accounts for 94% of Africa’s mining production of bauxite. The large mineral reserve, whic
