The bath employed by this process is stirred by magnetohydrodynamic flow and generally uses a mixture of sodium, calcium, and fluorides of the desired element. The more efficient method of this process uses solid carbon anode
The bath employed by this process is stirred by magnetohydrodynamic flow and generally uses a mixture of sodium, calcium, and fluorides of the desired element. The more efficient method of this process uses solid carbon anodes and is called pre-baked. This process is often preceded by the Bayer process and originally used a cryolite bath in which alumina, now replaced by bauxite, was dissolved. For 10 points, name this doubly-eponymous industrial process that was discovered independently by an American and a Frenchman and is used in the production of aluminum.
