Nowadays, with the increase of electronic waste, the way to process this kind of waste has attracted much concern. Circuit boards as the main part of electronic waste, also have attracted more and more people’s interest to recycle and even remove precious metals from it. So here we’ll have a talk of the most practical way to remove precious metals from circuit boards.
There are mainly two ways to remove precious metals from circuit boards now, it’s burning and dry type separation method.
Burning the circuit boards to get the precious metals, it’s a common but old method, which is almost undesirable now. Because on the one hand, burning could affect even have some destroy on the nature of the precious metals. On the other hand, the most important is that it could produce much pollution which is bad to environment and human health. That’s why this method to remove precious metals from circuit boards is gradually not welcomed now.

Another way is use dry type physical separation method to remove precious metals from circuit boards. It’s a scientific method and become the most popular way to remove precious metals form circuit boards. The precious metals is mainly contained in the chips on the circuit boards. So first we can use PCB dismantling machine to separate the electronic components out. The disassembled electronic components can be sold directly, and the bare board can be separated into mixed metal and resin fiber through the PCB recycling machine.

The PCB recycling machine is totally physical process and dry separation, so if you only want to get the metals out, then set up this is ok. If you want to remove precious metals from circuit boards, PCB recycling machine is the most practical way to recycle it.
