In the bauxite mines of Guinea-Conakry. In Guinea-Conakry, Colas is constructing the infrastructures required for bauxite mining operations. Beneath the surface of Guinea-Conakry are thought to lie half of the world's bauxite reserves, i.e. some 25 billion tons. The rock has a very high alumina content which is easy to extract in open-cast mines.
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 ...

CBG Bauxite Production Expansion. Fluor was awarded an engineering, procurement and construction management contract to expand Compagnie des Bauxites de Guinée (CBG)'s bauxite mine in Kamsar, Guinea. The project will expand bauxite production from 13.5 million to 18.5 million tons per year and is CBG's first of a planned three-phase expansion.
Bauxite is the ore from which aluminium is derived. Guinea has more than seven billion tonnes of bauxite resources, over a quarter of the world's total. Much of Guinea's bauxite is amongst the highest quality worldwide. GAC's mining concession covers an area of 690 square kilometres and contains one of the largest bauxite deposits in Guinea.
Set to become a world leader in bauxite and alumina Guinea holds substantial world-class reserves of bauxite, both in terms of quality and quantity, and was the world's fifth highest producer of the ore in 2014 (source: World Bank, Commodity Markets Outlook, January 2016). With the recent entry of a number of new industrial players into production and an increase in the production capacity ...
The Surinam Bauxite Company then became Suriname Aluminum Company (Suralco). The Brokopondo agreement, mainly provided for the construction of a dam, a hydroelectric power plant, a bauxite melting plant, an aluminum mining installation and the extension of the rights to water, bauxite concessions and land for geological research.
