Other notable Aluminium producing countries include Egypt, Cameroon, and South Africa. The world's biggest mining companies include MBendi, Alcan't, Rio Tinto, BHP Billiton, Anglo American,...
Alumina is used for the production of aluminium metal, through the Hall–Héroult electrochemical smelting process. The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production.
Bauxite Mining Aluminium is the third most abundant element in the Earth's crust, but does not occur as a metal naturally.

Bauxite deposits mostly form on or near the surface of the earth, by decomposition under moist tropical or subtropical conditions, of clays and clayey limestones and igneous rocks with high aluminium silicates content.
Jul 20, 2002· During the preparation of a site for opencast mining, the surface soil is removed to get access to the bauxite. In order to avoid soil erosion and to ensure that vegetation is returned to the land, many companies have water drainage practices during mining operations, separate removal of top soil (50 per cent reuse it directly after the mining ...
Greek Bauxite / Ore deposit geology/ MiningProduction The bauxite deposits in Greece are of "karst" type. They were created by the lateritic weathering of basic, mainly, members (basalts, diabases, gabbros) of the ophiolite complexes, which abound in the Subpelagonian Zone.

Jul 08, 2017· And, most bauxite (98%) occurs close to the surface, with just about 2% overburden. That means massive surface mining could kill the rivers, wipe out flora and fauna over tens of kilometres. A conscientious extraction that protects the sanctity of the rivers and streams – or the provision of permanent alternative water sources – is crucial and must be well laid out and .
Weathering of limestone gives rise to eroded surface and subsurface features (caves depressions) which are together known as 'karst'. If the voids are subsequently filled with minerals containing aluminium (eg. clays or laterite) then further weathering may occur leading to bauxitisation. The resulting deposits are known as karst bauxite. They are important in Europe, China and Jamaica.
