Procedures and apparatus for electrolytic production of metals

摘要

A cell for electrolysis of magnesium chloride in a molten salt bath to produce magnesium metal and chlorine gas, having downwardly tapering graphite anodes with opposed major surfaces slanting throughout their vertical extents, and cathodes disposed in spaced, upwardly divergent slanting relation to the anode surfaces. Electrolytic production of the metal is effected by passing current between the facing anode and cathode slanting surfaces through the bath, which is essentially nonreactive with the carbon of the graphite anodes.
