The apparatus that uses this process has a series of reduction pots sitting beneath hoppers containing the ore, and the MHD forces generated during this process causes stirring of the sample, which decreases its purity but increases performance.

The overall reaction produces three molecules of carbon dioxide, some hydrogen fluoride, and four molecules of pure metal. The molten sample is placed between an anode of fused coke, which is often prebaked, and a cathode of graphite, and the sample is dissolved in compound of calcium and sodium fluorides known as cryolite in order to reduce its melting point. Usually following the Bayer process and first employed by the Alcoa corporation, for 10 points, name this process used to extract aluminum metal from alumina, named for an American and a Frenchman.
