How to extract gold from e-waste?

With the acceleration of the replacement of electronic products, the amount of discarded printed circuit boards (PCBs), which are the main component of electronic waste, is also increasing. Environmental pollution caused by waste PCB has also attracted the attention of various countries.

In fact, these electronic waste circuit boards have high recycling and economic value and are a real mine waiting to be mined. So how to extract gold from e-waste?

First, we need to disassemble the recycled waste circuit boards. After disassembly, the above electronic components can be disassembled to obtain a circuit board template. Because some electronic components contain precious metals, the next step of precious metal refining, such as ordinary gold, can be carried out in advance.

The template obtained by dismantling the waste circuit board is first broken by a crusher and then ground. The obtained powder contains metal powder and resin powder. At this time, it is necessary to use an electrostatic separator and specific gravity for separation. The machine sorts and separates the resin powder and metal powder inside to obtain pure resin powder and metal powder for recycling in the next step.

At the same time, in order to avoid dust pollution, waste circuit board recycling production lines are generally equipped with dust removal equipment to avoid secondary pollution during waste circuit board recycling.

All in all, circuit waste and waste circuit boards can be turned into treasure through a series of recycling processes. If you need, please feel free to contact us. We will provide reasonable solutions according to your actual needs.
