In the hydrometallurgical recovery of gold from electronic waste ( Fig. 2 ), the PCBs are leached by a suitable lixiviant, usually after chemical pre-treatment. 50 The resultant pregnant leach liquor then undergoes a separation step to obtain single metal streams from which pure metals are obtained, for example by electrowinning.
