[@gelosul]

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.

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.

As I understand, there are gold threads left inside the ceramic plates!!! You have only taken the visible parts with gold which is a loss. Try to crush the ceramic plates into fine powder and look for the gold that remains in the form of thin wire.

[@OwlTech333]

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"

Tylko gdzie kupic te 14kg pozłacanych plastików? Jak masz pomysł to zrób to sam. Pozdrawiam,Tez Andrzej

[@albusdumbledore6772]

@@AndrewAndretti to nie jest 14 kg pozłacanych plastików tylko 14 kg procesorów komputerowych. złoto znajduje się w każdej elektronice i z każdej elektroniki można to złoto wytrącić. nawet w kartach sim jest złoto.

That was cool when the torch turned it into gold!🤠👍💯

You Will get more Money selling them as Working Processors and little Johnny in 2044 will not need to Pay as Much for a 486 or Pentium Dos Box .

thats about 5.695,69€

Yes

but how much did the CPUs cost you and everything else you had to buy for this project? @@OwlTech333

[@battleshippotemkin560]

Неплохой результат! Слиточек впечатляющий.

Спасибо!

[@ewasterecovery]

Do you recall about how much silver you got from this recovery?

[@OwlTech333]

About the same as the gold

[@OwlTech333]

We added 300g scrap silver contact points at 80% purity (which is around 240g Ag) and recovered 430g dore with contained 90g Au the remaining 90-95% of the dore being silver

[@David-f8o2o]

Crush the left over ceramics as there is more gold in them !!

I hope you have a very good filtration system if not your inhaling lead

I do

Interesting ! where go the lead in cupelling with stainless steel ?

[@OwlTech333]

It turns into lead oxide (slag) which is then skimmed off. It is saved for lead recovery

[@jakuborvos1575]

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.

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?

After lead bath, we add silver with molten lead solution before cupilation process?
