In pyrometallurgical processes, e-waste is blended with other materials and incorporated into primary/secondary smelting processes (e.g., into Cu or Pb smelters) at 1200°C (Table 3.3). Cu smelting is the dominant route for e-waste recycling, where PMs are collected in Cu matte or black Cu. In the final stage of Cu production, i.e., the electrorefining process, pure Cu metal is produced and the PMs are
