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 ...
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.
Julia Brainerd Hall (November 11, 1859 – September 4, 1926) [1] was the sister of American scientist Charles Martin Hall. She supported him in his discovery of the Hall process for extracting aluminium from its ore. [ 2 ]
The most promising was the Heroult-Hall process, separately developed by P T L Heroult in France and C M Hall in America in 1886-1887, but it required large amounts of electricity. The rights to using the process in Britain were obtained by the British Aluminium Company, which was formed in 1894.
