<p>A processing method by which metals may be recovered at a high purity from metal-containing waste materials (1). The method for processing metal-containing waste materials (1) comprises crushing a metal-containing waste material (1) to a particle size of 1-50 mesh, separating and recovering the metal-containing particles from the crushed portion, introducing the metal-containing particles into a vacuum heating furnace (2,3,4,5,6), pre-heating the furnace (2) while under suction evacuation, and then raising the temperature of the furnace in stages (3,4,5) while continuing the vacuum suctioning, recovering the metal and non-metal vapor produced at each temperature level using a condensing and adsorbing means (10,11,12,13,14,15) and recovering the liquated metals as melts. The method may be used to process waste batteries, copper-containing waste materials and the like in the same manner to recover high-purity metals. <MATH></p> |
