Amazing. Nothing can replace gold of course. Good for us, giving advice not to do in your home or i was ready to do it.

But it’s still interesting and fun to know that it’s technically possible to recover gold from motherboards using a homemade process.
Homemade process? where does someone find 95% concentrated sulfuric acid for home use? I've read cockroaches can swim in sulfuric acid and have always wanted to test that :p

Now lets all send Tom's all of our old Motherboards and add in cards and see what we can come up with. I've got about a Dozen.

I have worked in a lab with dangerous chemicals, and this reaction certainly uses dangerous chemicals. You would need the following equipment to work safely with these chemicals:
1. Fume hood (which the author obviously didn't use)
2. Chemical gloves (which he did have)
3. Chemical-resistant apron (which he didn't use)
4. Full face shield (we didn't see his face)
5. Closed-toe shoes or boots (we didn't see his feet)
6. Emergency eye wash and emergency shower (we didn't see these)
.
So basically, it's a "don't try this at anything less than a university lab" type of procedure.

I have about 30 or 40 mobos and diff old circuit boards with gold on them what are the names of some of these companies that recycle these? Do they pay for them or is it donation only?

MU made some good points about safety there but I will assume the THG team had all of the PPE.

I would imagine the older mobos and peripherals would have had more gold deposited on contacts than newer ones.

The price of gold was much lower in the past for a start.

I am thinking those Russian X86 clone CPU's would have been a great source of gold, along with high end Mil Spec components.

The inside of older Klystrons and other microwave devices would have also been a good source.

Mil Spec Cannon connectors ... other avionics components and cabling.

Great article Yannick.

That was actually somewhat interesting.

Though just for an idea on the scale of things...
Gold was worth ~$450 per troy ounce in 2005.
There are ~29,167 troy ounces per ton.
318 tons of gold equates to $4,173,797,700.
4 trillion dollars in a single year, back in 2005.
With gold closing at $1185, and growth in the electronics industry, can you imagine what kind of numbers are involved in this year?

[citation][nom]Tamz_msc[/nom]A very nice, off-the-track article![/citation]
Certainly, i would really like to see an article where toms get the most out of an motherboard, GPU or other add in card and processors, and to analyze the quantities used of gold and other metals along the evolution of computer hardware.
