Abstract
A rotatable furnace for treatment of metallic scrap is fed metallic scrap comprising at least two metallic components having different incipient melting temperatures. The furnace is heated to a temperature at least equal to the lowest incipient melting temperature of the metallic components but less than the incipient melting temperatures of other components in the scrap while rotating the furnace to agitate the scrap. The combination of heating to the incipient melting temperature and agitating the scrap serves to fragment the metallic component having the lowest incipent melting temperature. The scrap is then removed from the furnace, and the scrap is segregated by particle size. Fines representing dirt and other impurities may also be separated therefrom.
