Golden Ping!..........................
People who currently retrieve the gold from circuit boards are not interested in that gold doing anything with co2, they want the gold itself.
Less deadly than C uhoh 2.
“chemical-free method”
“synthesized a set of organic materials known as covalent organic frameworks linked with vinyl”
The article quickly contradicts itself.
Beautifully written and ready for inclusion into 1) grant applications from the federal government and 2) the prospectus for luring venture capital to invest in Zadehnazar's BIL's newly formed LLC.
LOL…California do-gooders hoist on their own do-gooder petard. Figures.
I don’t see anything about the cost of this method.
If it cannot produce more value than it costs, it is useless.
There’s already a widespread simple way to turn carbon dioxide into safe organic material, plants.🌱 🌲🌳
Thanks Red Badger.
The Youtube channel "sreetips" has many videos detailing how to extract and refine gold and silver. It takes some special safety equipment to deal with the chemical fumes.
It's probably heavily dependent upon scaling. Doesn't sound like it's there yet. But at the current price of gold, I'd bet he'll have takers.
The back yard smelters that the Chinese use to “refine” gold are far worse than anything I have ever seen. If this causes them to only produce half as much pollution as they currently do, it is a win-win for everyone.

This is the key take away.
““It’s estimated that a ton of e-waste contains at least 10 times more gold than a ton of the ore from which gold is extracted.”l
Having worked in Guyana on a gold mine I can assure you getting gold from Ewaste is more environmentally friendly than hydraulic mining. You first strip mine off all the jungle above the deposits, then using high pressure water hoses you turn to liquid all the underlying strata with the runoff going into sluces where the dense material is separated from the lighter clays and muds. You then use acids to leech the microscopic gold particles out of the remaining materials. All the runoff goes directly into the local watershed untreated I might add. Gold is $2600+ TOZ today if they got 99.9% out of ewaste they are making money for sure as its gold content is an order of magnitude higher than ore you can use chemicals in the $100+ per litre range and laugh all the way to the bank. MOF are cheap they are industrial chemicals used in tonne quantities for such things as catalysts for hydrocarbons cracking they are valued in dollars per metric tonnes not dollars per ounce.
Every ounce recovered from waste means hundreds of tonnes of earth under pristine jungle doesn’t get washed into a River system in the third world and that’s a good thing. I was there for a university friend of mine his father owns the mine and I am a geochemistry expert his son is a hydrologist you need both to hydromine.
Some reports tell us that an old-school PC contained an eye-watering $9 worth of gold. But that’s not counting the cost of removing it.
Some other sources estimate that your average computer contains about 1/5th of a gram, or about $12 worth, of gold in them. On the other hand, laptops typically contain about 1/10th of a gram of gold, or around $6 worth.
However, the actual value will depend entirely on the type of e-waste you are looking at. For example, industrial video equipment often has a proportionally higher amount of gold, sometimes above 56 grams per machine.
Need something like this for rare earths extraction
At a 99.9% recovery rate, it would be very nice if it would scale at a reasonable cost.
Lots of gold out there in tailings piles might become valuable.
“Led by post-doctorate researcher Amin Zadehnazar”
Is this in Iran?
What is the net cost of this process?
And how much waste is still left? (99% I bet)
