Current trends in gold recovery from electronic wastes

Electronic wastes (e-wastes) refer to abandoned electrical and electronic equipment (EEE). E-waste contains significant concentration of gold which is 10 times more than its concentration in gold ores. It approximately contains 10–10,000 g of gold/ton, whereas the gold ore contains barely 0.5–13.5 g of gold/ton. In this chapter, …
