摘要:Worldwide for manufacturing hightech products like PCs, cell phones, tablet computers and other electronic and electrical devices, 320 tons of gold and 7,500 tons of silver are required respectively. When these products reach the end of their usable life, they become Waste Electrical and Electronic Equipment (WEEE). More than 50 million tons of WEEE is produced in the world annually. Out of it less than 15% of the gold in WEEE is recovered for reuse. Opportunity for recovering not only valuable metals like gold and silver but also many other metals like copper, tin, cobalt, palladium and other precious metals from the discarded consumer electronics is lacking. These discarded devices end up in landfills creating potential health and environmental hazards. On the other hand, around 54,000 tons of gold is only available below the ground reserve. This will lead to face high demand for gold in upcoming decades. Hence it is necessary to recover gold from e-wastes and save it for future supply.
