Learn how aluminium is extracted by electrolysis using bauxite and cryolite as raw materials. See diagrams, equations, exam tips and examples for the CIE IGCSE Chemistry syllabus.
Learn how aluminium is extracted from its ore by electrolysis, using molten cryolite as a solvent. Find out the factors that affect the choice of aluminium extraction site and the challenges of the process.
The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground.
The Hall–Héroult process is the major industrial process for smelting aluminium. It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium 's chief ore, through the Bayer process) in molten cryolite and electrolyzing the molten salt bath, typically in a purpose-built cell.
Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery .
Learn how aluminum is extracted from its ore, alumina, by electrolysis and other methods. Explore the history of aluminum discovery, production, and applications from ancient times to modern industry.
