    1999-5-7 · 2.2.1 The electrolysis process2 In the Hall-Héroult process, the electrolyte is molten cryolite (Na 3 AlF 6) in which 2–8% of alumina (Al 2 O 3) is dissolved. To lower the melting point, industrial cryolite-alumina mix-tures also contain various amounts of other salts, such as aluminum fluoride (AlF 3) and calcium fluoride (CaF 2

  • How Aluminium is Made Tiwai Point

    2018-9-19 · NZAS uses the Hall-Heroult process to reduce alumina to aluminium metal. The basic inputs are alumina, electricity and carbon. In this process, alumina undergoes an electro-chemical reaction in individual reduction cells. These cells are long steel shells lined with refractory bricks and carbon and are connected electrically in series.

  • Extraction of Aluminium (Aluminium Ore) Hall

    Hall-Heroult Process. The Hall-Heroult process is widely used in the extraction of aluminium. In Hall-Heroults process, pure Al 2 O 3 is mixed with CaF 2 or Na 3 AlF 6. This results in lowering of the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with the lining of carbon and graphite rods is used.
