No, in those times in our area 10g of 24k gold was of ₹4,600 which is hardly 150 dollars

Why?

I am a nerd and I am horrified in 2023 as well. :) Some of those CPUs worth probably more than the gold from them.

@@_RandomGamer ask your parents how long it took them to earn 4600 rupees back in the day

I'm horrified now

Glad you enjoyed it

I collected for 3 years and just started to process mine. Whoooo its not easy. Shit goes sideways and before you know it, you are like where my gold.....fuk ....er? LOL One thing they do not stress enough is get your filtering process down, practiced, built, understood... before you do anything. That's where it first can start spiraling out of control. You literally forget if you keep the solution or whats on the cotton... Cross contamination starts happening as well if you are not careful. Ive been a mess for weeks now. LOL

@@GarageBandDad i expect the author to reply to this

I completely agree! Filtration is one of the most important steps in the refining process (if not the most important). If the solution is not crystal clear you’ll have a hard time precipitating pure metal

.4 g of gold per CPU? I seriously doubt that

@@joergkalisch7749 what do u think? How much gold in 1 cpu?

@@twistr99 a few milligram

@@joergkalisch7749 thanks

@@joergkalisch7749 Old processors have much more gold than modern ones, some models even have 0.5 gram. So his math isn't too far away i would say around 0.2 average, still selling working processors would earn you a lot more..

Thanks!

Nope

Lead oxide is reduced back to lead metal by smelting with flour and wood charcoal and reused

He has a ton of CPUs already and he doesn't do 32 bit computing anyway. Besides these chips are going to be poorly stored in hot warehouses, have bent/broken legs, etc.

Yes

Yes

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.

Welcome back!

Many many thanks

Did you watch the whole video?

You need someone to spoon feed and wipe your ass too ?

Thanks

Yes a tiny amount

Thank you!

The client insisted on recovery only despite the refining would have been another extra hour

That’s what I was thinking with aqua Regia could of saved time with super acid but ended up with one hour plus on lead bath

Is the scrap the most expensive part or is the fuel and chemicals?

Agree

All sorts of high yielding ceramics

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.

mainly pentium pro / pro 2's, pentium1 / 2's sx and dx 2 / 4's....

Have you ever seen the ads on alibaba for cpus I emailed a company and they quoted me $10,000 to ship a ton of them and when I say a ton I mean exactly that and it was $7000 and $3000 for shipping to where I'm at in nm. Now I'm aware that most are probably scams but the quote was actually for pretty good quality ones. What is your take on these do you think its a scam? Have you ever bought from any of these people overseas ? Because I'm real skeptical

No need to, thermal shock does it for you

I add additional silver

Probably $5k-$6k

Thank you!

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.

@@OwlTech333 considering the cost of silver , it's no more than 60$ worth if even that.

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.

@@John-ir2zf those are exposed at the moment the cpu hits the molten lead

It is very important

Don't forget that gold in 1999 (that seems to be about the vintage of these chips) was going for $450/oz.

@@kevinrusch3627 Oh yeah, I know that. I was just shocked when I did the math and learned how much the gold in each chip is worth today.

Correct, ceramic ICs were about 1,5kg

Ok

$3,000 roughly
