  History of Inventions and Innovations for Aluminum Production

  2020212 · Industrial production of aluminum started in 1856 with the chemical method developed by Sainte-Claire Deville. In 1886, Charles Hall and Paul Héroult invented the electrolytic reduction of alumina with carbon, which quickly became the only industrial method used to produce aluminum until today. Even though the Hall-Héroult process …

  Could the chloride process replace the Hall-Héroult process …

  2019328 · At present, the Hall-Héroult process is universally used in the production of aluminium. It is an electrolytic process in which aluminium oxide is dissolved in molten cryolite (Na 3 AlF 6) and then reduced electrolytically to aluminium at a temperature of around 960°C. The process uses carbon anodes that are consumed during the …
