Which circuit boards have the most gold?
Here are some “golden age” items that have large printed circuit boards and therefore, comparatively large quantities of gold.
- Jumbo old video-playing devices like VCRs and Sony Betamax players.
- Old camcorders – the bigger the better.
- Early digital still cameras – again, the bigger the better.
How much gold is in a circuit board?
The gold content present in the PCBs depends on the type of PCB used in each device, and may vary between 140 and 700 g of gold per tonne of PCB. The gold content found in these PCBs is much higher than the average levels found in gold ore, which is currently 5-10 g of gold per tonne of ore.
Can you extract gold from circuit boards?
There’s gold in them thar circuit boards — laptops, phones, cameras and other devices use the precious metal to connect components, and it can be extracted relatively simply. A typical handset holds around 0.2g of gold, which means about £1.80 for your pocket.

Is there gold in computer parts?
Gold: Gold is used in printed circuit boards, cell phones, computer chips (CPU), connectors and fingers. Silver: SIlver is used in printed circuit boards, cell phones, computer chips, keyboard membranes and some capacitors.
How much gold is in a CPU?
A computer contains about 0.2 grams of gold, valued at about $12….How Much Gold is in a Computer, Laptop, Cellphone.
| Electronic Device | Amount of Gold Present in grams | Value of Gold In Device |
|---|---|---|
| Desktop Computer | 0.2 grams | $12 |
Do all circuit boards have gold?
Today, Printed Circuit Boards that Contain Gold Are Everywhere. And the good news is, electronic scrap contains gold and other precious metals that can be extracted by an experienced precious metals refinery.
Where is the gold in a motherboard?
Gold is found in numerous places on a motherboard: IDE connectors, PCI Express slot, PCI, AGP, ISA, and other ports, jumper pins, the processor socket, and DIMM (SIMM on older motherboards) slots. All of these connectors are often covered with a fine layer of gold a few microns thick, deposited by flashing or plating.
Where is gold in computer parts?
Motherboards – the biggest circuit boards inside both laptops and desktops – often contain the “mother lode” of gold in used computers. Their edges have gold contacts and connectors where wires slide on. You will also find thin layers of gold applied to motherboards’ surfaces.
Where is gold located on a circuit board?
Gold in these circuits occurs as a layer over a base metal substrate such as nickel or copper. Separate the gold-plated metal parts in the circuit boards using a magnet. Some gold-plated parts may be inside ceramic components.
How do I recover gold from circuit boards?
You can recover the gold plating from the circuit board fingers in several different ways: some time consuming, some expensive and some just plain dangerous and toxic. But probably one of the quickest, easiest and safer ways to remove the gold involves soaking the circuit board fingers in a solution of circuit board stripping powder.
How do you remove gold from a circuit board?
Removing Gold Using Nitric Acid Get protective gear. Purchase concentrated nitric acid. Put your circuit boards in a glass container. Pour the concentrated nitric acid into the glass container with the circuit boards. Stir the mixture using a glass rod until the contents become fluid in form. Drain the nitric acid from the mixture.
What electronics have the most gold in them?
Short Answer: Computers and televisions typically have the most gold of any household electronics. Cameras, radios, and media players – especially older models – also contain gold in their circuit boards. Other electronics like game consoles, tablets, and phones only contain trace amounts of gold.
