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.
They cost a lot of money if you are trying to buy them as scrap from Ebay or something. Everyone knows how much gold they contain. A lot of times it's not worth it to buy the expensive processors, then do the procedure.

Cool video. I'm a little surprised you didn't redissolve the gold in aqua regia with a bit of sulfuric acid added to precipitate out any remaining lead. Still, it looked pretty good at the end and well worth the time depending on how much the scrap cost.
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!!
With the overall cost of everything used in this process, is the amount of gold reclaimed worth more than the cost of the processing? In other words does it turn a profit?

there's gentlemen on RUclips, Adrian's Digital Basement, who does vintage computer restoration and he is often short on some chips, I think it would be worth your while if you asked him for a list of components to look out for when people send you scrap, you can probably get much more than melt for those chips!

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.
Dissolving the alloy in nitric acid is not a process identical to inquartation. They are two completely different processes, with completely different purposes, ending in completely different results.
@@OwlTech333 Inquartation is a process where you ADD base metal to an alloy. Which then goes without saying, the result of inquartation is an alloy with a larger percentage of base metal. Nothing has been dissolved yet at the completion of inquartation.
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.
I want to conduct this experiment on a small scale, with a quantity of 1 kg. Could you please provide me with the composition of lead and silver in the furnace process?

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.

@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.

How much is 14kg of CPUs ? Is there any profit in this work?
2-3k USD
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
I want to conduct this experiment on a small scale, with a quantity of 1 kg. Could you please provide me with the composition of lead and silver in the furnace process?
1kg of what? Material or lead?
GOLD from transistors - test run

@@user-fm6hd5bo7q 0.5kg lead in a proper crucible should suffice and 50g silver which should be added after the “bath”
After lead bath, we add silver with molten lead solution before cupilation process?
what is the white powder you pour before torching ? thx
Borax
Boric acid would be better
Perfect !!!
Thanks!
