Conditions within the digester (caustic concentration, temperature and pressure) are set according to the properties of the bauxite ore. Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C. The pressure is not important for the process as such, but is defined by the steam saturation pressure of the

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 smelting is the process of extracting aluminium from its oxide, alumina, generally by the HallHéroult is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.. This is an electrolytic process, so an aluminium smelter uses huge amounts of electricity; smelters tend to be located close to large power stations, often hydroelectric ones

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively,
The smelting of aluminum begins with the extraction of bauxite ore by a form of open cast mining. The bauxite is washed and screened before being converted to alumina, a white powdery element from which the aluminum is produced. Aluminum smelting is carried out in a Hall Heroult reduction cell, which is lined with carbon. A mix of alumina and cryolite is fed into the cell and carbon blocks
Gibbsite is an aluminium hydroxide (Al(OH)3), while böhmite and diaspore are both aluminiumoxidehydroxides (AlO(OH)). The main difference between the latter two is that diaspore has a different crystalline structure to böhmite. Differences in ore composition and presence of iron, silicon and titanium impurities influence their subsequent processing.

Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process. This process is referred to as primary production. TakeAway

Aluminium Wikipedia. The chief ore of aluminium is bauxite Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments, Machinery and equipment (processing equipment, pipes, tools) Aluminium is used because of its corrosion resistance, nonpyrophoricity, and mechanical strength.

Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. It is a silverywhite, soft, nonmagnetic and ductile metal in the boron mass, aluminium makes up about 8% of the Earth''s crust, where it is the third most abundant element (after oxygen and silicon) and also the most abundant metal.
