Some quick maths here for whoever in interested: If average CPU weight is 60g then that would mean there would be approximately 233 CPUs. They would have to be sold at about £20 each to have the same value as the gold resulted from the melting.maybe less if I knew how much silver was melted. So conclusion is that depending how old they are it might not be worth putting them back on the market and melting is better option. I did not take in to account the time and materials of the melting process as I'm not familiar with the costs.

Then I saw what this guy was actually doing in the video and immediately realized "Oh... THAT'S why?" This is both real and crazy.
What do you mean the silver is a nice bonus at the end? Seeing how you added 300g silver... how much silver was recovered at the end to make it a nice bonus?
The silver from the picture is almost a kg. The nitrate from the dissolution step was mixed with other nitrate from previous refining. You get silver form the CPUs as well as gold. The added bonus is the refining of this silver which usually weights more than the gold recovered.
Only allowed in certain unregulated parts of the world? Cupelling without a cupell must be called "sending the lead oxide downwind". But interesting for the simplicity.
Would you be willing to make a video on all the materials you screen out of the lead baths and try to do a recovery video from the bits of metals left on them? I’m sure there’s a small percentage of pms left behind that alloyed with the silver/lead and clung to the materials. Thank you!!

Honest question.... Why didn't you crush the chips ? Inside of those sandwiched ceramic plates are tiny gold wires from each pin to the chip. I doubt the gold escaped from between the ceramic plates without breaking them open.
There's no gold bonding wires inside the ceramics! From GRF: "A standard ceramic CPU is made of several layers of ceramics bonded together. between the layers (while the ceramics is still unfired, also called green) is screen printed conductors of molybdenum. The ceramic body is then fired and the molybdenum that is exposed is then gold plated. On the bottom or side, pins are brazed or soldered and in the cavity bond wires are used to connect landing pads on the die with the exposed gold plated conductors. For bonding wires aluminum or gold can be used. Inside the ceramic body is the molybdenum conductors and the only gold is the exposed gold and the gold under the die. To use gold inside the ceramic body would be problematic. Thermal expansion and contraction will break conductors over time unless it expands with the same rate as the ceramic body. Molybdenum is the solution on this problem and it is cheaper that gold. Göran"
@OwlTech333 thank you for the info.... Though I'll still crush mine since your copied article clearly says "for bonding wires, aluminum or GOLD can be used". It's a small quick step and if it liberates more gold, I'll go through the extra step.
That’s awesome. Do you have a chemistry background, or just self taught/ learned from experienced coworkers? When I get the space, I want to set up a vented small extraction lab
First time coming across something like this, needed to do some math.... Assuming 40 grams per CPU average, 14 kg would be 350 CPUs. From 91 grams gold that works out to about .26 grams of gold per CPU. That jibes with what I have seen reported elsewhere, at least assuming a high yield on recovery. Also, I never realized that these old CPUs contained about $15 in gold each.
Faut les trouver les 14 kg de processeurs, même en faisant toutes les déchetteries de ma région pendant un an, je ne suis pas sûr d'arriver ne serait-ce à 10kg ou alors, faut acheter des lots mais est-ce que au final, ça sera rentable ? J'en doute

Interesting ! where go the lead in cupelling with stainless steel ?
It turns into lead oxide (slag) which is then skimmed off. It is saved for lead recovery
Skimmed as lead oxide, about 10 or so % PbO vaporize in the process. If the cupel or cupelling tray is used, PbO is soaked into the cupel.

Sir full detail video gold recovery plz
Do you use Borax when you melt the gold?
Yes a tiny amount
Nice recovery.
What weight was the silver recovered?
700g but it is mixed with silver from other extractions
Good job and excellent money to day ❤❤
Thank you!
When you dissolve the Dore in nitric acid, do you apply heat?
Yes
So it is better to not crush your chips? Or is it better to crush chips? Can you please elaborate.
Don’t crush the chips if this is the method you’re going to use
Hello sir from where i can buy online 486 and 386 processors scrap ? Please reply
Can provide if show bobs and vagene
How much did the recovery cost?? I mean if I somehow had access to huge amounts of e-waste,
how much would it cost to recover the gold from 14Kg of CPU or other electronic items?
This is like asking me how much it will cost you to get to Paris or other cities in the northern hemisphere… for 14kg of this particular type of electronic waste (ceramic CPUs with kovar pins) using this method will set you back about $50 fuel and chemicals
@@OwlTech333 Thanks that's all I wanted. I understand different inputs will have different recovery costs. Oh and for me to get to Paris right now, about US$1500 😊
Some of those CPUs would have sold for more than their gold value, to CPU collectors and retro gaming buffs.
One or two but not all
Hi
Excuse me, may I ask you? Is the extraction of gold and silver from electronics scrap of good financial value, or is it only for recording videos?
