Extraction Process of Aluminium from Bauxite Ore
Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes. Bauxite is the general name given to the hydrated oxides of aluminum. It contains varying amounts of
9. Mining or industrialization specialization?
Aluminium production in Africa is about three times higher than consumption, but while the former is, for the most part, exported, the latter is covered mainly by imports. Africa''s relative shares in world output are 14% for bauxite, 0.02% for alumina and 2.6% for aluminium.
Tin was first replaced by aluminium in 1910, when the first aluminium foil rolling plant, "Dr. Lauber, Neher & Cie." was opened in Emmishofen, Switzerland. The plant, owned by J.G. Neher & Sons, the aluminium manufacturers, started in 1886 in Schaffhausen
