Apparatus for melting relatively large floating units of metal scrap in a molten melting media or medium, the units having oxide films and solid, liquid and gaseous inclusions. After the units are charged into a melting medium, layers of freshly melted metal are presented to the molten media. The apparatus includes a bay for heating the molten media and means for pumping the media from the heating bay to a circular bay for receiving the large units of metal scrap. Located in the circular bay is a rotor means for moving the media therein at a velocity sufficient to sweep away the surface and insulating layers of the floating units in a rapid manner such that new metal is rapidly and continuously exposed to the melting media without the floating units being submerged in the media. A third bay is included for collecting skim material from the molten media leaving the circular bay. Inlet and outlet troughs extend tangentially to and from the circular bay for directing molten media respectively to the charging bay from the pumping means and from the charging bay to the skim collecting bay. A combustion chamber is located adjacent the charging bay for burning organic material vaporized in the charging bay.
