ABSTRACT:
A method for the purification of a metal selected from the group consisting of aluminum and aluminum alloys, wherein the metal is in a liquid phase and is contacted with a salt flux consisting of a binary mixture of NaCl and MgCl2. Preferably, more than 22% by weight of the binary mixture consists of NaCl.
