how aluminum is produced

  • Aluminium - Element information, properties and uses ...

    Most commercially produced aluminium is extracted by the Hall–Héroult process. In this process aluminium oxide is dissolved in molten cryolite and then electrolytically reduced to pure aluminium. Making aluminium is very energy intensive. 5% of the electricity generated in the USA is used in aluminium production.

  • Aluminium life cycle

    The aluminium atom in alumina is bonded to oxygen and needs to be broken by electrolysis to produce aluminium metal. This is done in large production lines and is an energy-intensive process, requiring a lot of electricity. Using renewable power and continuously improving our production methods, is an important means to meet our goal of being ...
