Abstract
Removal of magnesium from a magnesium-containing aluminum alloy is obtained by melting the aluminum alloy, superposing a layer of molten flux containing chlorides or fluorides upon the molten aluminum alloy, and passing an electric current between the molten aluminum and the molten flux for thereby causing magnesium to pass from the aluminum layer into the flux layer and form magnesium chloride or magnesium fluoride.
