Abstract

In a method of melting, or purifying magnesium, and magnesium alloys, the molten metal or alloy is agitated with a fluid flux of calcium chloride and sodium chloride in the presence of a protective atmosphere that inhibits oxidation. The flux may also contain barium chloride, or a fluoride of an alkali or an alkaline earth metal. To provide the protective atmosphere sulphur in vapour or solid form, nitrogen containing carbon bisulphide, or a volatilizable fluorine compound may be introduced into the melting pot, or fluorine or a fluorine compound that is gaseous at ordinary temperature, with or without a diluent gas, may be passed over the surface of the metal. Specification 395,633 is referred to.
