On this issue, electronic components contain a certain amount of gold, so recycling electronic components can extract gold. The following is the general recycling process:
1. Collect electronic waste: including discarded electronic products, computer motherboards, circuit boards, etc.
2. Disassemble the electronic components: disassemble the electronic products, remove the circuit board, and separate the electronic components.
3. Crushing electronic components: Use special equipment to crush electronic components and make them into powder.
4. Gold refining: The use of chemical methods for gold refining, generally including soaking, screening, precipitation, filtration and other steps.
5. Refined gold: The gold extracted by high temperature smelting is refined.
It should be noted that electronic components contain a certain amount of harmful substances, such as lead, mercury, etc., and environmental protection measures need to be taken when recycling to avoid pollution to the environment.
