Abstract
The thesis employs glycine processes to recover base and precious metals from waste printed circuit boards. Different alkaline glycine-based leaching systems were proposed and investigated in-depth. Leaching behaviour of various metals was discussed. Different options for copper recovery from leachates have also been evaluated. The thesis provides a sustainable and de-centralised hydrometallurgical approach to treat the problematic e-waste, particularly in countries like Australia where the e-waste volume is limited and the geography is vast.
