I’m a 15 year old who literally has no relation to this field of work, this is really interesting and I easily stay up at 2 in the morning watching the full video
I admit to being emotionally attached to those chips you're so cavalierly breaking up. I was the design manager for the Pentium Pro processor and it's follow-ons. There was a lot of blood, sweat and tears that went into making these devices. Figuring out how to put two die in one package economically while maintaining a high speed bus connection was hard.....But, technology moves and what we invented then continues in other processors today. Still hard to watch these being broken up for the elements....:)
One of the best parts about your videos is how clearly you speak and how you produce such quality sound, I really appreciate that you have a microphone headset.
I’ve been following you for awhile sreetips, I am an electrical mechanical engineer and we build generator for locomotives. Ever since I saw your refinement of brazing rods I have kept all my scraps nibs they range from 15% to 50% silver. I have pounds of the scraps I would like to refine soon. I was wondering if you could do a video on some of your lab materials. Such as where to purchase the acids, glassware* I have a bunch*, crucibles, safety equipment and PPE, and other vital materials. I am in the process of setting up my fume hood right now. I think this info could be beneficial for the new hobbyist. Your followers understand that you’re a busy man with all the work and content you provide for us and we thank you. Keep up the great work.
I've watched at least a dozen videos on this topic and yours was 100% the best one with clean clear instructions. I'm still not sure If I'm going to bother doing it but it sure was fun to watch.
Not all pentium pro cpu's contain the same amount of gold. You need to check the Cache level on them when you buy them. the 512K cache contain more gold than the 256K cpu's You also might want to re-check the ceramic pieces before you discard them. There is usually gold brazing UNDER the silicon Die, if you don't break them up enough, there might be trapped gold under the die
Dang thats interesting. Would have never thought cache would have anything to do with the PM content. Amazing how much money we used to spend on these "latest" processors vs the scrap value now. Talk about a depreciating asset.
I was thinking a grinder/powerizer would be cool. Help to get everything exposed. Create more surface area. He could do it with the silver-gold alloy also. (Electrum? Or is that only 𝘯𝘢𝘵𝘶𝘳𝘢𝘭𝘭𝘺 occuring?) It looks like delicious, clumpy brown sugar if he doesn't, though.
Please stop encouraging people to destroy vintage CPUs. A quick check on ebay will demonstrate that it is completely uneconomical, and simply an exercise in wanton destruction.
Dear sreetips You work really hard on this channel and I appreciate your efforts. you are publishing videos almost every day I've learned a lot from you I wish you the best in your life
Yield is low when you compare to what Sree works with day in and out, but compared to any other ‘waste’ material in the world that’s an amazing return. Your yield was spot on for the chip type. Your amount of pre-processing required compared to all other non-ceramic CPU’s is what makes that recovery rate so good, cause all you had to do was smash and add acid, which cannot be said for the other forms of e/waste material. Huge savings in time.
From one veteran to another, thank you for your service! I have been watching most of your videos and learning how to refine precious metals. Nitric is too expensive and I'm not brave enough to try to make it myself (yet). The question I have with this method is: What is the temp outside? I was thinking about doing this with some CPUs and fingers from a collection I have and wonder if the cold weather (30F/-1C) slows down the process?
I believe you are missing some gold under those caps. Remove the caps/lids on the cpu's before you smash them. There is gold brazing underneath the caps. Back Yard Scrapper just did a video a couple of months ago on these cpu's, and showed this step. I really enjoy your videos and you are a great teacher.
Have watched several of your videos and really appreciate the detail and explanations of the chemistry involved. My background is more in the organic field, so I recognize that there a many other subtleties that aren't covered in depth. I do want to emphasize, for example, that a good fume hood and other protections are critical so that people remain safe. And while I love how your camera work that allows us to see the in-process pours and collection, the viewers should be cautioned that pouring acids or any strong chemicals toward the body can be very dangerous and is being done to show the work. Your videos are very interesting and helpful to me.
Thanks again for another video. I'm happy to see some lead sulfate, and I still think it would be awesome to see a heavily saturated solution of it precipitate in another video
Its really is best to just remove the soldered caps with heat than remove the silicon die with heat as well. The ceramic remains intact but the acid can hit every spot were gold inlay, brazing etc hides under the dies but it can be done anyway one wants to do
There is a process I read for making monatomic gold that uses HCl and H2O2 to dissolve it. That form of gold has some pretty unusual properties . One of which is evading detection with regular methods including mass spectroscopy. What if some of the gold was lost in the very beginning?
Shipmate was wondering if you used a magnetic stir stick in the bottom of the beaker on a magnetic stir table. Does this work instead of using air bubbler
CPU's like the pentium pro are held in with a clip and do not come into contact with any solder but it is still the best practice to add sulfuric acid.
As sreetips has figured out, the plating process in electronics doesn't involve pure gold, it's a process in steps involving other metals. Some volume processors melt all the metals and pour them into the shape of cathodes. The gold ends up in slimes at the bottom of a tank.
May be a silly question but when using an oxyacetelene torch to heat PMs do you have to have the darkened eye protection similar to a welding helmet? Ive never had an oxy ace torch.
So I'm curious about this process, had you used more scrap would you have had to increase the amount of the solution or would you have been able to yield more returns for the effort put into it?
I'm surprised you don't use a filter pouring off the rinse water then burn off the filter at the end as usual. Get all the gold and forget the drain waste. Great to see you found your shipmate. Fair winds and following sea.
@sreetips where do you get your chems at? Your main ones I guess the nitric is what I mean is it local or by mail I can't find a good rate so I make my own ( very time-consuming) I have a local place but they are insanely expensive any thoughts or experience on this would be nice thank you in advance
I buy mine from GFS Chemicsls. But they don’t deal with the public. You must have a company (LLC easy to set up in most states) and they won’t ship to residential address. Check dudadiesel.con
I don't think I have seen you using AP very often 👍 its my main process so thank you 👍 Edit, im absolutely amazed by the tiny amount from those, i had been lead to believe they are far better in term of return.
I've not yet started to refine my gold yet. I know Ewaste is alot lower yield than karat but that is the majority of what I've been hoarding for many years, and I have collected alot over that time! I'm looking forward to seeing the yield. My expectations are very realistic though! I love it when you do the Ewaste video as I'm sure many others are as well. Have a Great Day My Friend!!!
Good video on why e waste is a bad investment for the home refiner. The pc mic volume sounds so much more clear than before, I think you should stick with the volume you set it at
I bought like 40 of these pentiums and a bunch of military grade pins, glassware, melt dishes, smb, B.funnel, filters etc etc. 9 or so years ago when I started watching Indeeditdoes. Only thing holding me back was a fume hood. Maybe I could setup an outside unit like yours to start learning again! One day ima get that gold out lol. Great vid as always!
If your doing it for the science great. If your just after the gold you might want to check the prices of the chips you have and just sell them, then buy some gold you will get more plus less hassle haha.
I agree, the chemistry is fun to observe and it's exciting to succeed at it. 9 years ago, might make a profit. I did the same but stopped trying to use tons of acids and just melt pretty much anything I can if ceramic is involved. Cheaper to just burn out the metals and pour shot to hammer and roll thin, then acids. I found myself no matter what, always ending up with gold still inside the ceramic. I disliked the time grinding up ceramic by hand in cast iron crucible.
CPUs especially on Ebay people are wanting more $ than the yields more and more. I have heard that the older rear projection TVs are some of the best yields but they come with a large amount of useless product also but they are easy to find for free on Facebook Marketplace & Craigslist. As always another great vid and you always make me miss our towns Ace Hardware that went out of business few years ago
ol' Sreetips!!! Great video as always! Quick question that you vets might make in a video or perhaps just write back.. In the final steps of adding stump out and borax: The amount of stump out to use in reference to the stock? If two much is added best recommendation to fix the mess. Same thing with borax, amount used and a fix if too much is added. Thank you Sreetips and Archimedes Channel for your educational videos
The yield confirms that AP is not the weapon of choice when it comes to gold recovery from CPUs. How about the silicone dies? Are they still attached to the ceramics? If they are there's alot of gold underneath. The silver in the braze is blocking the AP
When you switched to the PC mic, it sounded pretty good. Just a tiny bit muffled, but I'm hard of hearing so it could be my ears playing tricks on me. Oh, I'm using headphones if that makes a difference.
I've been collecting circut boards to recycle the gold from the highways but I'd like a demonstration as to how to do that.I think I'd burn the shalack off then further refine it.Please tell me if I am correct?

Sreetips I have to ask, why do you think these yielded much lower than your previous batches when the average was around .3 per PP or around 1.2g for 4

A couple of months ago I heard of someone buying a laptop computer at a thrift store and they found an envelope in the case with $1,900 cash. I believe it. You never know what you might find while thrifting.
My wife found a small gold pendant. The gold had no marking but she can spot gold by eye since she’s been doing it so long. The folks at the thrift store thought it was costume since it wasn’t marked and presumed that the stone was a CZ. She bought it for the gold for $2.99 and it turned out to be a nearly flawless one carat diamond.
@@sreetips I have found gold with free mason stamps they stopped using in 1912. I found a 4 gram 14kt charm last month at a swap meet for $1. It had no markings whatsoever. And I may have found a rare 1878 one dollar gold coin at a thrift store in needles CA last week and was told I could have it, because I bought a bunch of other stuff, including a 7.5 gram 10kt bracelet for $20. Picked off a 1.25 gram 14kt gold ring and an 7.5 gram 18kt white gold with 6 15+ point diamonds 2 weeks ago. Paid $5 each. Lol I'm building a pile of gold filled, and high grade electroplated gold costume jewelry too.
It's very easy to see why you don't recover gold from computer scrap. Unless you have a free supply of the scrap, it just doesn't justify the resources and time that it takes to do so. I'd even be wary if the scrap were free, the yield is ridiculously low compared to the amount of work required to recover less than pure gold. We've been duped into thinking that there is a gold mine in computer scrap, but it's just not so. Manufacturers use just enough gold to get the job done, and no more, and it's not even 24k (more like 12k). Thanks for the reminder, sreetips, that this is "no man's land" in gold recovery. Our time and resources are better spent on higher yield projects such as karat scrap and GF-GP pieces.
Definitely know better than to attempt that, lol. Sound was good with the sound change, maybe a touch low. 👍 Thank you sir for teaching me this valuable lesson. #teamSHTF
Does anybody know what the paper fibers become in that solution of acids? Cellulose contains C H and O, would that be producing traces of nitrocellulose?

On modern CPU’s, the solder between the die and the heat spreader has indium and silver in it to have a better thermal conductivity than lead.

Mic sounds way better. Old set up was quite jarring when you switched. Love the vids keep it up.
The leftovers in the filter might be palladium, from the gold plated capacitors on the top of the CPU’s 🧐
i still have some Pentium Pro's but always thought they had more gold then this.
Will not break them up.
Gold binds to carbon easily. Fine particulates that concrete with the carbon are inductive and reflect no light. Ergo black residue in filter.

was using the oxide solution preferable to a nitric bath because nitric was cost prohibitive? and does the oxide solution dissolve silver if present?
The peroxide solution does not put gold or silver into solution at low concentrations. That is specifically why it is used here.

If ANYONE gives you any shade for smashing up some old processors, Mr Sreetips just send the my way.
If you ran the CPUs through a crusher mill I wonder if it would make the gold easier to extract? Just a curiosity.
Hammer mill
Good sound quality Kevin!
Is there anyone you would recommend buying gold plated pins or chips from?
No, if you find any for sale, they will be grossly over-priced.
Pc adjusted mic level eliminates background noise 👍
I'm suprised you don't need to pulverize the ceramic first. There aren't any gold filaments embedded inside?
The Pentium Pro and some other older Pentium CPU's use a Tungsten heat spreader that may be affecting the chemical reaction.
I have a couple of those processors like you have there. And a lot of the newer ones. Like 5 pounds of it.
Perhaps if you had a grinder you could recover more gold. I think there is gold embedded in the ceramic that was not exposed to the
aqua regia
Sreetips I have to ask, why do you think these yielded much lower than your previous batches when the average was around .3 per PP or around 1.2g for 4
I rushed it. Over confidence, pressure to finish. Behind on my more important upcoming videos. This list for my low yield is endless.
@@sreetips see thats how one should answer question, if you mesw up take responsibility and be honest shit happens. You should check out that video from ewasteben, i dint understand why so many people are gullible on yield recover rates.
The heat spreaders contain tungsten, which can trap gold from AR. probably the black substance u saw was some tungsten that broke up
I checked a couple of vids on these types of CPU's they definately contain Silver so lots of the white stuff will probably be SilverChloride
Legend has it those had the most gold in them of all CPUs
You can filter the gold particulate and put the filter paper in the melt dish; you wouldn’t have left the gold in the waste container.
Volume is fine, I just needed to take it up a bit after your adjustment.

I'd even be wary if the scrap were free, the yield is ridiculously low compared to the amount of work required to recover less than pure gold. We've been duped into thinking that there is a gold mine in computer scrap, but it's just not so. Manufacturers use just enough gold to get the job done, and no more, and it's not even 24k (more like 12k). Thanks for the reminder, sreetips, that this is "no man's land" in gold recovery. Our time and resources are better spent on higher yield projects such as karat scrap and GF-GP pieces.
Couldn’t have said it better myself
INTEL made these chips in my hometown for many years. DEC and Intel kept my property value high for years
That right there is why I stock pile thank you I learned what I did wrong the first time I try
Definitely know better than to attempt that, lol. Sound was good with the sound change, maybe a touch low. 👍 Thank you sir for teaching me this valuable lesson. #teamSHTF
I always appreciate your time sir thanks for the video Sreetips
And there you are Joseph!

What temperature do you boil the aqua regia at please ?
It's all gonna boil at a set temperature. Like water, unless you boil it under pressure, it's gonna stay at 100C
Keep the videos coming!
People freak out when you dissolve these, they even used to be on TV adverts.
The mic level sounds better after adjustment btw 👍
If you are emotionally attached to Pentium Pro chips, it’s time to reevaluate your priorities.
Funny dude!
Agreed
I enjoyed this video, thank you mr streetips
Is there any advantage to using a peroxide that is stronger?
No, it is a bad idea as it will dissolve some gold
Hi sreetips. What will happen if you just add aqua regia on the broken pieces of processors? Is it difficult to purify?
It makes a very dirty solution
@@sreetips Thank you 😊
That yield was low for sure
you said the gold was on the botom of the waste bin how much was left therE?
I think it’s very interesting I would love to try this is there a step by step writing somewhere ?:D
I don’t know.
Hey! Looks like you made my request come true to see the lead precipitate. Cool stuff!
Pc mic level is perfect!
Awesome!!
New Valentine's Day card idea: I love you like Sreetips loves precious metals
I didn't cry when you smashed them chips. Just had dust in my eyes.
Does anybody know what the paper fibers become in that solution of acids? Cellulose contains C H and O, would that be producing traces of nitrocellulose?
By far, this is fantastic!!!! PPro is the créme de la créme of all eWaste
Nope! It's the PPro plastic fantastic the créme de la créme 😉
great video sir thanks for sharing
