Aluminium - Rio Tinto

Aluminium is made from bauxite, or aluminium ore. Bauxite is the basic raw material that is refined into alumina, which in turn is sent to smelters for processing into aluminium. First discovered near Les Beaux in the South of France in 1821, bauxite was initially called "beauxite". In 1886, Charles Martin Hall and Paul Héroult independently developed a process for making aluminium from ...

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 ...

Aluminium production process

The ore is loaded into autoclaves and treated with lime–caustic soda. Aluminium oxide appears in the resulting slurry while all the admixtures settle to the bottom as red mud. The sodium aluminate solution is stirred in precipitators for several days, eventually pure alumina or Al 2 O 3 settles at the bottom. REDUCTION PROCESS. At an aluminium smelter, alumina is poured into special ...

Alumina in Australia

Alumina is produced by treating bauxite ore with caustic soda in the Bayer process. This process involves digesting bauxite at high temperatures with caustic soda which dissolves the alumina as sodium aluminate leaving iron oxide and silicates as waste products (red mud).
