Recovery of copper through concentration processes from ashes produced by WEEE pyrolysis

The process of recovering metals from electronic waste has become an important topic in recent years. In this work, the recovery of electrolytic copper from the ashes produced during the pyrolysis process of waste electrical and electronic equipment (WEEE) was sought. Three gravimetric separation eq...
