ABSTRACT OF THE DISCLOSURE The invention relates to an apparatus for the continuous vacuum refining of a metal. The apparatus includes a cylindrical vacuum chamber, a stack of a plurality of vertically superposed trays disposed in the vacuum chamber for receiving impure molten metal and including interconnections for flowing the metal down- wardly from tray to tray while impurities are discharged therefrom. A heater is included in the vacuum chamber for heating the metal in the trays and for evaporating the impurities therefrom. A shield in the chamber surrounds the trays to trap volatilized impurities discharged from the trays and for condensing and discharging the impurities. The heat energy generated by the heater is irregularly distributed along the height of the stack of trays such that the heat energy imparted to the trays diminis- hes in a vertically downward direction.
