1Hall-Héroult process — The Hall Héroult process is the major industrial process for the production of aluminium. It involves dissolving alumina in molten cryolite, and electrolysing the solution to obtain pure aluminium metal.ProcessAluminium cannot be produced by the… …
2Electrolytic process — An electrolytic process is the use of electrolysis industrially to refine metals or compounds at a high purity and low cost. Some examples are the Hall Héroult process used for aluminium, or the production of hydrogen from water. Electrolysis is… …
