There are over 320 tons of gold and greater than 7,500 tons of silver used each year to make new electronic products around the world. As a result, there are more than $21 billion in precious metals inventoried in these devices—$16 billion worth of gold and $5 billion worth of silver, until a time when they can be recycled.
A record 53.6 million tonnes of electronic waste was generated worldwide in 2019, according to the UN's Global E-waste Monitor 2020. The raw materials in this e-waste were worth around $57 billion - with iron, copper, and gold contributing most to this value. But only a sixth of that value ($10 billion) is recovered in an environmentally ...
Kogan (2006) patented a technique for gold recovery from waste electronic equipment. The scrap was added to hydrochloric solution containing 180 g/L HCl and 250 g/L MgCl 2 for 3 h at a temperature of 80–95 °C. During this period 98% of aluminum, 94% of tin, 96% of lead and 94% of zinc were extracted in solution.
