Aluminum Smelting | HowStuffWorks

The alumin­um smelting process developed by Hall resulted in large amounts of pure aluminum. Suddenly, the metal was no longer rare. The idea of producing aluminum via electrolytic reduction in cryolite wasn't rare, either. A Frenchman by the name of Paul L.T. Heroult came up with the same idea just a few months later. Hall, however, received a patent for the process in 1889, one year after ...
