Introduction: With the upgrading of the information age, circuit boards, resistors, capacitors, and micro devices in various types of smart appliances have gradually been replaced, and these discarded Electronic Components have specialized personnel to recycle. What are the residual values?
Why does some of the discarded electronic components get recycled? Of course, because it still has some residual value, the most important value is the metal contained in electronic waste, especially precious metals. According to the literature, 1 ton of electronic boards randomly collected can separate 143kg of copper, 0.5kg of gold, 40.8kg of iron, 29.5kg of lead, 2.0kg of tin, 18.1kg of nickel, and 10.0kg of visible waste electronic clock. Precious metals.
Commonly used scrap metals are mainly recovered as precious metals such as gold and gold alloys, because the gold content in electronic waste is much higher than that of ore, which is generally several hundred times higher, and the recovery cost is much lower than that in raw ore extraction. Economic benefits are obvious.
In addition, the composition of electronic waste is complicated, and more than half of them are harmful to the human body, and some are even highly toxic. For example, a computer has more than 700 components, of which half of the components contain various toxic chemicals such as mercury, arsenic, and chromium. If classified and processed, it would be more environmentally friendly than direct disposal.
