According to the UN report, metals such as copper, cobalt, silver and gold in a mobile phone account for 23% of its weight. According to industry insiders, various precious metals can be extracted from the circuit boards of electronic waste such as mobile phones. About 130 kg of copper, 2 kg of silver, 0.4 kg of gold and 80 g of palladium can be separated in a 1 ton old mobile phone circuit card.

Due to the low recycling cost and low threshold, used mobile phones have become an important way for many small garbage factories to refine metals. Once these used phones fall into an informal e-waste processing plant, they are likely to have a major impact on the environment.

The recovery rate of new technology for circuit board recycling equipment is 99.90%. Non-ferrous metals and rare metals in waste circuit boards have important recycling value. For the recycling of waste printed circuit board PCB, the crushing-high voltage electrostatic sorting technology is a typical environment-friendly technology, which has the advantages of high efficiency, energy saving and no secondary pollution.
