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.

Aluminum - The Environmental Literacy Council

There are environmental impacts associated with each stage of aluminum production, from extraction to processing. The major environmental impact of refining and smelting is greenhouse gas emissions. These gases result from both the electrical consumption of smelters and the byproducts of processing.

The aluminium production process - European Aluminium

Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the so-called "bauxite residue", followed by a calcination step which removes the water content in the hydroxide.

Metal processing - University of Washington

Metal processing What is a Metal ? Structures of Metals . Metal Properties . In industry, molten metal is cooled to form the solid. The solid metal is then mechanically shaped to form a particular product. How these steps are carried out is very important because heat and plastic deformation can strongly affect the mechanical properties of a metal.
