  • Mining and Refining Process World Aluminium

    The crystalisation process is driven by progressive cooling of the pregnant liquor, resulting in the formation of small crystals of aluminium trihydroxite (Al(OH) 3, commonly known as “hydrate”), which then grow and agglomerate to form larger crystals.

  • 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.
