  2. Hall–Héroult process - Wikipedia

    en.wikipedia.org/wiki/Hall–Héroult_process

    The Hall–Héroult process is the major industrial process for smelting aluminium. It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite , aluminium 's chief ore, through the Bayer process ) in molten cryolite and electrolyzing the molten salt bath, typically in a purpose-built cell.

    en.wikipedia.org/wiki/Aluminium_smelting

    The Hall-Héroult electrolysis process is the major production route for primary aluminium. An electrolytic cell is made of a steel shell with a series of insulating linings of refractory materials. The cell consists of a brick-lined outer steel shell as a container and support. Inside the shell, cathode blocks are cemented together by ramming ...

    Bust of Heroult in Thury-Harcourt. Paul (Louis-Toussaint) Héroult (10 April 1863 – 9 May 1914) was a French scientist. He was one of the inventors of the Hall-Héroult process for smelting aluminium, and developed the first successful commercial electric arc furnace. [1] He lived in Thury-Harcourt, Normandy.

  5. Aluminium recycling - Wikipedia

    It involves re-melting the metal, which is cheaper and more energy-efficient than the production of virgin aluminium by electrolysis of alumina (Al 2 O 3) refined from raw bauxite by use of the Bayer and Hall–Héroult processes. Recycling scrap aluminium requires only 5% of the energy used to make new aluminium from the raw ore. [2]

    The HallHeroult process produces aluminium with a purity of above 99%. Further purification can be done by the Hoopes process. This process involves the electrolysis of molten aluminium with a sodium, barium, and aluminium fluoride electrolyte. The resulting aluminium has a purity of 99.99%. [46] [144]

    In 1891 after Cowles began to advertise "pure aluminum" they were sued by the Pittsburgh Reduction Company. The judge announced his decision in January 1893, finding them to be infringing the patent of Hall and having gained knowledge of his process by hiring away a chemist named Hobbs who was the foreman in Pittsburgh.
