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

Mining and Refining – Process - World Aluminium

The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production.

machines used to mine alumina

Aluminium production process All About Aluminium The process where the aluminium is shaped to its required form. This process is used for making the vast majority of aluminium products from spectacle frames, telephone bodies, aeroplane fuselages or spaceship bodies.

Production process - EUROPEAN ALUMINIUM

Aluminium can be rolled into sheets from which aluminium foil and beverage cans are made, as well as parts of car bodies and a vast array or other products. Using the forming process of extrusion, the aluminium is shaped in its required form and delivers almost unlimited possibilities in product design.

How aluminium is produced

The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current.
