Gold is used not only in the jewelry industry, but also in electronic products – in printed circuit boards. It might seem that mining gold from used mobile phones is not a bad idea for a startup.
This was decided by a Weibo user under the nickname Chef Alchemist, who bought 210 printed circuit boards from smartphones for $ 1.5 apiece. In the process of extracting gold, it is necessary to carry out a number of chemical and physical processes (purification, dissolution, filtration, and so on) using acid and other materials. As a result, he was able to extract only 0.41 g of gold from these boards. In the local market, this is no more than 30 dollars.
That is, the cost of only the purchase of printed circuit boards turned out to be 10 times more than the cost of the gold received. It is also worth considering the cost of tools and chemicals.
Mydrivers notes that if the scale of processing is large enough, and the process is put on the conveyor, then extracting gold from mobile phone circuits makes sense. According to data published by Mydrivers, 16 tons of copper, 350 kg of silver, 34 kg of gold and 15 kg of palladium can be obtained from 1 million mobile phones.
However, the gold mining process is very polluting, and various chemicals also have a negative impact on the health of workers. Therefore, these productions are being phased out or banned in China.
