Is there gold in circuit boards?
Ever noticed those shiny gold-colored parts on the circuit boards? Those bright pieces of metal are, in fact, gold. Gold is used on electronic circuit boards because of its excellent conductive properties and because it doesn’t corrode or rust over time.
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.

Computer CPU’s (processors) have the most precious metal value by weight, followed by Memory (RAM) & Circuit Board Fingers / Connectors / Pins, then Circuit Boards (Motherboards), then cables / wires, with hard drives & whole computers being last.
Are circuit boards worth money?
The circuit boards found inside a single newer laptop can contain gold worth between $15.00 and $25.00. That’s not as much gold as you can typically find in a big old laptop, but it is hardly chump change – especially if you can get your hands on 50, 100 or 500 of them. Don’t overlook tablets either.
Does anyone buy old circuit boards?
You can sell the circuit boards in your computer and other electronic equipment to electronic recyclers or metal refineries. Printed circuit boards contain gold and copper. Recyclers can reuse some elements of the circuit board directly or melt down the entire board to harvest precious metals.

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.
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 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.
