Abstract

Light metals, particularly aluminium, magnesium and their alloys are refined by incorporating in the molten metal, if not already present therein, a reducing substance which is at least partially volatile at the temperature of the molten mass and adding an oxidizing agent which yields its oxygen to the added reducing agent, the reducing agent in turn transferring the oxygen to the impurities to be eliminated. Suitable oxidizing agents are alkali chlorates, perchlorates, oxychlorides, chromates, bromates, iodates, perborates, permanganates, cyanates, nitrates, nitrites, and manganese dioxide, copper oxide, &c., and suitable reducing substances are the alkali metals, zinc, cadmium, sulphur, and sulphur dioxide. The treatment takes place under a flux such as the alkalies or their halogen salts.
