A Gold BB
The result is a pretty gold BB!
Economically speaking, is it worth all the trouble? Definitely not. The process is only viable if it’s done on an industrial scale. The little ball of gold we recovered is only worth two or three dollars at current prices. And in fact, companies that recover the gold from old computers use other techniques and chemicals that are even more dangerous. But it’s still interesting and fun to know that it’s technically possible to recover gold from motherboards using a homemade process.
It’s also possible to recover gold from add-in cards, processors, and chipsets. But that’s a story for another day.
