$33 from 10 old motherboards? Lot work for a little money
Give Me Liberty or Give Me Debt
I recall reading about this some years ago.
The problem is where are you gonna get the boards, basically for free?
The office product stores will let ya turn in your old computer for recycling, but they don't pay you any money for it. So only they would make any serious money off this.
It is interesting. But it doesn't address how all the electronics and an entire computer can be sustainably recycled. Even if you can reasonably extract the valuable gold, there are so many other environmental issues which is likely why most electronics recycling is done in China, and a lot of that outside their own regulations. That is why Cadbury started marketing Cadmium Creme Eggs.
i dont see a real payoff here, if they were making money with it it wouldnt be for sale (unless its a learning thing))
Isn't there technically a certain amount of gold in sea water?
Maybe extracting gold from the ocean might be more lucrative. 😉
They first liquidfied the boards (disolved)? How was that done? What acids or combo of acids. Does not make sense to me. If the gold is in suspension why not just precipitate it out? No need in whey or cheesy stuff. Just good old stump out from the local hardware store.
