The best known sources for gold recycling are motherboards from home computers. Other sources are mobile devices, tablets, printers and all other devices with some electronic circuits inside.
Parts which contains a certain amount of gold are: IDE connectors, PCI slots, PCIEx slots, AGP, ISA and parts like these. In addition to these we have stated gold contain memory slots, CPU sockets and other connectors like these.
In fact, gold can be found in almost every important junction of an electronic circuit. To make components work smoothly each contact is coated with a layer of gold.
Thing you should know is that percentage of gold inside these circuits is small. The reason for that is because of gold price. Before recycling processes all parts containing gold should be removed from the other elements, such as plastics, sheet metal and similar materials from which the components are assembled.
Separation of components is essential because the gold is recycled using acids. It is very important to minimize the possibility of acid contamination.
If you want to extract gold from motherboard it is important to take that motherboard apart and to separate parts for recycling. We already mentioned which parts contain gold and which not. Plastic can be removed, and all connectors placed together for recycling.
Because there is just small amount of gold inside one motherboard, we suggest for you to collect few motherboards and then try to recycle gold from them. In that way you can see how gold can be restored and exchanged for money.
