Abstract of the Disclosure Gas is injected into molten metal, such as aluminum, to purify the molten metal either of dissolved gases (degassing), or of dissolved solids such as magnesium ("demagging"). The apparatus for accomplishing this injection contains two metallic bath chambers, the molten metal being transferred from one chamber to the other through a conduit. A gas injection conduit is connected to the metal transfer conduit at a location submerged within the first metallic bath chamber from which metal is transferred to the second chamber, and the gas to be injected is introduced through this gas injec- tion conduit into a location submerged within the first metallic bath chamber. - 1 -
