Abstract

Improved procedure for the electrolysis of alumina, especially applicable to the manufacture of aluminum by igneous electrolysis of the alumina, characterized in that said alumina dissolves in a cryolite bath consisting of a mixture of sodium cryolite (Al F raised to 3.3 NaF), lithic cryolite (Al F raised to 3, 3 Lif) and potassium cryolite (Al F raised to 3, 3KF).
