By the way, SMB doesn't exactly "dissolve" in water. It reacts with it, forming the transient sodium bisulfite, which is unstable in the absence of water. If left to evaporate and recrystallize, you won't have purified SMB, you'll have a mixture of sodium sulfite, sulfate, as well as a little H2SO4, and SO2 gas is released as the water to contain it goes away. Doesn't really matter for the process other than to say it has a shelf life once it is mixed with water (and oxygen in the air) to retain the "SMB properties", but worthy of mention, as SMB's function in this ultimately is to release SO2 gas.
I love to see you extract small quantities of gold from computer fingers and chips, and gold filled scrap. Many may not appreciate how hard it is to do this whilst keeping your yield figure high. It shows great skill and understanding. And demonstrates your excellent laboratory technique. I've moved from
You give me hope for ~11 lb of plated component lead clippings... I think I'm going to go with the reverse plate (sulfuric) route. I just kept saving and saving it up and the mine has finally bottomed out, so it's time lol From there thinking a good HCl rinse, dissolve (probably HCl/NaOCl) and then electrowin the gold on a cathode. I don't have a means to melt it, and it's in a more or less solid bulk form plated out like that. Excellent video as always man.
Mostly the cemented copper ends up in the final waste bin. I was thinking it would be cool to them use that copper to inquart gold for refining but I think using silver is more cost effective because you can end up with cemented out 98% pure silver from the process versus copper which is anywhere from $0.50-4.50/lb.
@@robertclark2959Perhaps better to make it into something and sell that. If I am going to pour an ingot why not pour it into a green sand mould instead. For example copper hammers that sell for 80 bucks. When you make a small run of a product you learn so much and get better and better at it over time.
@brianbonenberger8054 copper is in the same boat as silver. There are no more large deposits of ore to be found. It is all now elemental copper that needs processed. This is what is driving the price of copper and silver. On top of this, the production of solar cells, EVs, computer components, cell phones, rechargeable batteries of all types ect.. a all dependent upon silver and copper for the intrinsic conductivity of both. Add a growing rarity of Orr to the exponential growth of production needs for both silver and copper, we will see an incredible increase of value, for these elements, never seen before. Copper is a pain to process. I do it as I'm interested in putting the copper back into usage, environmentally speaking. It generally isn't cost effective. This being said, if you believe all the predictions, it will become more worthwhile as the value of copper continues to increase. Silver? Now is the time to buy and process Sterling. Even buying 99.9 Fine bullion. It is going to experience value growth as never before witnessed, over the next 3 to 5 years. Buy Silver. Sit on it. You'll make more returns on your investment than on any other commodity in existence! I'm in process of moving ALL of my assets into Silver. Gold is still a solid investment, to be sure. Only Silver is going to experience a growth in value that will blow your mind! The window to buy Silver is there; but, it's closing. Buying Siver is a, No Brainer"! It will not loose value. It will not crash, as markets and bank can. It is an investment that has solid concrete value.
You are welcome. A piping hot production! It’s nice to know we'll get to see some of the waste solutions from this series show their shine on an upcoming, and highly anticipated, upload. Thank you Sir!👍👍🤟
I just wanna say that i got respect and admiration for you just as much as if you were my father. You're an amazing person with many spiritual qualities, and i have nothing but respect for you.
Perhaps not the most economic way to do it. I think there are cheaper acids that desolve base metals. It's been so long, but I think I used hydrocloric , a bubler and time. In any case, i still love watching you videos.
You are making me rethink sending 1000's of computer parts to a recycler each month. Oh boy I wish I had time to trim those fingers off and stash them, thanks that was a fantastic end to the series!
With 7 pounds of fingers, he's getting a .37% gold content at 12 grams of gold. He got 11.3 which is .35% actual but he did have some waste gold so its probably closer to .36% actual. If anyone is wondering.
I made six videos. And recovered 27.3 grams of pure gold. 17 pounds x 453.5g = 7709g of scrap. 27.3g divided by 7709 = .0035 or 0.35% - hope my math s correct.
fascinating processes on your channel. Gold is such a beautiful metal when it is refined to .999 pure. just currious, how do you wash your glassware? Do you have to boil or autoclave? Maybe just a dishwasher? Thanks
Most of the solutions are acidic. Quick rinse with distilled water to remove the chemicals. Then I scrub with Alconox lab glass soap, rinse with tap water, rinse with distilled water, air dry in the dish washer rack
Dude. I freaking love your videos. I feel like a kid on a school night who wants to stay up and watch tv...except i wanna stay up and watch u refine and i gotta be up really early for work😅
I like the way you used different precipitation methods from the recovery to the refining stage. That probably helped the with having high purity at the end.
That was really impressive - your process keeps improving every time you do this and that yield shows it - that was really close to what you predicted! Also what an awesomely beautiful button! Did you skip the Borax because the gold was already triple refined? Awesome video! 👍
I would love to see a collab between you and MBMM comparing a time/cost/return comparison for this type of scrap. Theirs being primarily pulverization and mechanical separation with a shaker table, then consolidation with primarily bismuth, and refinement with cupelling.
I have a confession and a question. I've been watching and subscribed going on two years now. Despite the fact that you have the channel name written in big, black, bold, capital letters on nearly everything in the video, and say the name in every video...this WHOLE time I've thought it was STREETIPS. I thought maybe a play on "street tips".. I'm so embarrassed, but now I just gotta know.. What does SREETIPS mean?
Theoretically for few grams of gold, you added liters of Nitric acid just because of the volume. Chemically you might be doing everything right. From economic and efficiency angle, if you add mechanical force (shaking or stirring) to your process, I am sure some acid and time could be saved. For example, when you are dissolving filter papers, you add a stirrer to your beaker. Now that you are doing a big batch of 7 pounds, if you periodically stir the gold fingers after nitric acid, it will fasten the process. Some foils which became lose but still stuck to the plastic because of the sheer weight of the batch could fall down if you stir. Otherwise your video is enjoyable like always.
@@sreetips The bones are also made of copper. Twist one apart and you'll see. That's why you always get a dirty solution after going to aqua regia, there's still a 3rd and 4th layer of copper in those PCB's.
Great video once again, sreetips! I'm not into precious metal recovery, but I love anything related to chemistry, and your content is always top-notch. I thoroughly enjoy your work.
Have you seen any of the videos where they pull the pads off the board first? they just use a big thick soldering iron and run it across and they just fall off. Not sure it's worth the time, but it's definitely a smaller volume to work with once done.
The ferrous cloride precipitation is cool and all but nothing beats the magic SMB precipitation! Will you please consider pouring the solution directly onto the SMB in a coming video? I believe you did this once before in a video and the reaction was just awesome! Great video like always and I appreciate all the money and hard work you put into these videos. You're the best on TH-cam by far and I'm proud to say I've been watching for many years now!
sreetips has said on numerous occasions that the copper waste isn't worth his time to do anything with. But I'd love to see SOMETHING be done with it. Maybe it could be sent off to one of the other TH-camrs that does metal casting like bigstackD?
I wonder whether having a deeper and rounder melting cup (test tube shaped rather than dish shaped) would produce nicer, ball-shaped golden beads with less loss... I suspect some of the gold stays stuck on the sides of the relatively "flat" melt cup and some of the metal sublimates because it needs to be heated longer to aggregate if it's spread out more... Either way, beautful gold bead mr Sreetips... once again you've proven to be a Grandmaster of the Gold :)
Morning Gunny! Have you ever considered using a centrifuge for separation of parcipitate from solution? I've been using one to separate my boils when the solution refuses to go through the Buckner filter. It works trig! I decided that I'm too old to wait for 1 Earth gravity to drop my parcipitate. Cranking up things up to 20 gravities or so with a centrifuge really helps. The one I purchased from Amazon, can handle 200 ml at a go. I think that you'd find it an invaluable tool! Looks good on the Lab bench also 😂! Enjoy all your incredible videos! I wish I had a way to show you my first ever production run, poured ingot with our LOGO on it! All thanks too you, my dear friend, who got me started in this incredible, "hobby"! Thanks again for suggesting GFS CHEMICAL! They have, hands down, the best prices, extensive product line and services! I'm expecting my first delivery of HN03 this week from them! Thanks for all you do! Wade
@sreetips I get that. It's a pain loading 8, 25 ml test tubes, with the parcipitate that drops. I have found that it's worth it for all that refuses to filter. My vacuum pump is also a HVAC evacuation pump. Possibly, I don't have a good enough seal for the vacuum to pull as it should? I've got a new Borisciliate glass evacuation Buckner Funnel coming, with an aggressive locking seal, between the flask and Funnel. The side arm is actually on the glass Funnel, rather than on the side arm beaker. Would you recommend using sealing grease, at the junction? I don't like using the grease as it's easy to contaminate the parcipitate with it. Do you use sealing grease? One last thing. Amazon Prime is having Prime Deal Days, ad I'm sure you're aware. They have some really great prices on magnetic stirring hot plates, shaker plates, (shaker plates work trig on settling parcipitate), and glassware. I purchased a few 5,000 ml beakers for $29.97 each. Just a heads up, as it were. Thanks again, my Friend! You are who I want to be when I grow up! 😁 Your Friend, Wade
I'm not a chemist by any stretch, but I'm curious: Do you think the gold has some other metal alloyed in it, and that's why gold from these circuit boards falls out of solution more easily? It appears to be quite pure at the end, but I'm wondering specifically if there's copper in the plating gold, and if that could cause it to need to be inquarted?
would it make it any easier to put the circuit board fingers through a blender or some sort of crusher to have better surface area for everything to dissolve?
Nice wrap to the Computer scrap series! I have a suggestion for a video Sree. I saw this guy precipitating gold with a solution of stannous chloride, would you give it a try? I think it would be a cool experiment
Actually, that comes from narrating, operating the camera for best angle, and performing the task, all at once. I’m starting to look forward to the day I don’t have to do it anymore. My wonderful hobby has become work. Someone once said that if you turn your hobby into your work, then it becomes just that, work.
Have you ever talked to Jason from Mt. Baker Mining and Metals? I would love to see you guys collaborate on electronic waste. He has a channel here on TH-cam. He has a machine that pulverizes e-waste and separates the metals from all of the junk. Seems like about a year ago he was showing how he could produce bags and bags of the stuff and was asking if people had any idea how to more efficiently separate the precious metals from the base metals.
Weird question: would 100% pure gold powder fuse into a solid metal in a vacuum? I've read that steel can self weld in space, so just curious if gold would as well!
I don't think it's the same, because gold doesn't oxidize. Nasa had problems with using silver and other metals.on circuitry because they would oxidize and crystallize and short circuit electrical boards. That's why gold is so important in circuitry. It's high conductivity and low oxidization. Also, it has a low reactivity. That's why nasa moved away from using silver and lead circuitry in satellites. I don't think it would self weld.
Why are you using Nitric acid instead of Acid/Peroxide? AP can be regenerated indefinitely and reacts less with the Gold. (Gold is slightly soluble in Nitric Acid which is how Aqua Regia works). You used about 2 liters of Nitric acid which costs about $30. AP would cost about $3.
@@WarkWarbly I missed that. That much Nitric is a big cost but I guess it is the cost of business. I use Iodine to strip Gold plate and the startup cost is really high but it is easily regenerated.
he doesn't it that way because he says it takes too long. I tried to explain it to him if he uses heat or even an air bubbler while doing it, it would take less than 2 days.
17 pounds of scrap yielded 27.3 grams of pure gold over six recovery videos. 17lbs = 7709g so 27.3g pure gold divided by 7709g of computer scrap equals 0.0035 or 0.35%
In recovery gold from computer scrap you need to be carefully of the presence of tin metal in it, because it's could be reduce the yield. To prevent this you need to submerge the computer scrap to the solder remover solution, HCL would work but it take forever to remove the tin, so i would teach you how to make the solder remover first disolve 15 gram of urea in 30ml of hot water then add 21ml 68% conc nitric acid to it then swirl it it would form a white crystal of urea nitrate which is high energetic material so becarefull with ATF, then add 800ml of distiled water and mix until the urea nitrate disolve, add 50g of citric acid to the water, last add 200ml 50% conc nitric acid to the solution and mix. Sreetips i request you make a video more often about recovery gold from computer scrap because it would be a great topic on your chanel, thank you.
I keep wondering about the history of the chemical process used. Who ever thought that you could dissolve gold into a liquid 🤔 It would've saved alot of robberies in the good-ol-days if they thought the barrel was nothing more than liquid human waste 😂
BE VERY CAREFUL DOING WHAT SREETIPS IS DOING HEED ALL WARNINGS AT THE BEGINNING OF HIS VIDEOS MICHAEL AT MY NEW HOUSE I WILL BE BUILDING EXACT COPYS OF HIS SILVER CELL TO GROW THE PURE SILVER CRYSTALS 💰💰💰
In past videos you broke down the cost vs recovered metal and spot price comparison. Just curious, I’m guessing between chemicals and cost of scrap, I’m guessing it was probably a net loss vs buying at spot price? I get you don’t do this because it’s “easy money” and there is value in recycling and educating folks, plus TH-cam revenue and the ability to sell for a premium since many are willing to pay more because this button has a story, but just curious!
Love the video, I have a two part question. How do you measure out the Ferrous Sulfate and the water? And what is the name of that white item that you placed your melting dish on?
The book calls for a pound of ferrous sulfate for every fifty penny weight. A pound is 453.5g and 20 penny weight is a Troy ounce (31.1 grams) so if I have an ounce of gold (31.1 grams) I’ll use about 200 grams of ferrous sulfate. That amount should dissolve in a half liter of hot distilled water. The white insulation is ceramic wool. Don’t try to use fiberglass. It will just melt and stick to the melt dish. I get ceramic wool at Grainger.com
That is pure genius to put the gold into solution while still nominally attached to the fiberboard fingers! A pure timesaver, too! Nicely done, Senior!

By the way, SMB doesn't exactly "dissolve" in water. It reacts with it, forming the transient sodium bisulfite, which is unstable in the absence of water.
If left to evaporate and recrystallize, you won't have purified SMB, you'll have a mixture of sodium sulfite, sulfate, as well as a little H2SO4, and SO2 gas is released as the water to contain it goes away.

Wade
Those ground glass seals are tight. I use a Corning hotplate stirrer. Thirty bucks for a 5 liter beaker is a good deal.
Is it cost effective with the chemicals you use to gold? Great job, I don't see why industry can recycle everything now a days instead of land fill.
That little red crack on button turned out to be your trademark now.
SREETIPS HOW IS THE SILVER CELL DOING???
It’s resting quietly.
I was wondering if it had been running this whole time and we were about to have a super massive cleanup... 😂
Amazing.The most beautiful button I've ever seen.
where do you think the other 7/tenths went, smb waste pot?
Not sure.
Beautiful button.
Pounds?
I wonder what proportion of the value of recovered gold is taken up by processing, chemical costs etc?
❤ the channel. That's a crazy amount t of fingers!
Loving this job ❤
I'm addicted to watching sreetips, I wish I had a place and knowledge to do this.
Good work team
I'm not a chemist by any stretch, but I'm curious: Do you think the gold has some other metal alloyed in it, and that's why gold from these circuit boards falls out of solution more easily? It appears to be quite pure at the end, but I'm wondering specifically if there's copper in the plating gold, and if that could cause it to need to be inquarted?
Yes, there’s copper in the gold and that’s what turns it green.
So many steps to get to this to precipitate.
Good morning Chief AU 😊, gud vid 👍💯👌🔥
Gooooood afternoon from central Florida! Hope everyone has a great afternoon!
Goooood afternoon
What's going on with the silver cell?
Bravo. was surprised 😯
Does this guy have all that acid is his backyard??? Imagine thieves breaking into his home, they will be dissolved in nitric acid :D
They won't be dissolved in acid, but that might get riddled with holes! High speed lead, . you get the picture.
Good fences make good neighbors. Lets not worry about the things that are not ours to worry about.
would it make it any easier to put the circuit board fingers through a blender or some sort of crusher to have better surface area for everything to dissolve?
Honestly I think you would lose more on the crusher teeth or whatever than would be worth the time or acid savings.
Probably not
Nice wrap to the Computer scrap series! I have a suggestion for a video Sree. I saw this guy precipitating gold with a solution of stannous chloride, would you give it a try? I think it would be a cool experiment
you getting brave... doing stuff one handed with the nitric... and bumping or hitting the hand with the cup in it being complacent
Actually, that comes from narrating, operating the camera for best angle, and performing the task, all at once. I’m starting to look forward to the day I don’t have to do it anymore. My wonderful hobby has become work. Someone once said that if you turn your hobby into your work, then it becomes just that, work.
They would never happen if I didn’t have that pesky camera in my way all the time.
Very beautiful❤
Dang. sounds like a lot of computer cards and boards to get 7lbs of fingers.
Better to collect them, then throwing them away in a land fill am I right?
Yep.
There were several thousand fingers. All trimmed from circuit cards. Just imagine how many PCs it took to generate that many trimmed fingers
About 920$ of 24k
great video!
Have you ever talked to Jason from Mt. Baker Mining and Metals? I would love to see you guys collaborate on electronic waste. He has a channel here on TH-cam. He has a machine that pulverizes e-waste and separates the metals from all of the junk. Seems like about a year ago he was showing how he could produce bags and bags of the stuff and was asking if people had any idea how to more efficiently separate the precious metals from the base metals.
Yes, I’ve had contact with him through the comments section on his channel. He has since learned to use nitric acid to separate the metals.
Nice. Is the profit margin large enough to make it worth the effort if the price of scraps and chemicals is taken into account?
I don’t think so
@@sreetips Ah well. It's interesting anyway and at least you get something back!
Weird question: would 100% pure gold powder fuse into a solid metal in a vacuum? I've read that steel can self weld in space, so just curious if gold would as well!
I don't think it's the same, because gold doesn't oxidize. Nasa had problems with using silver and other metals.on circuitry because they would oxidize and crystallize and short circuit electrical boards. That's why gold is so important in circuitry. It's high conductivity and low oxidization. Also, it has a low reactivity. That's why nasa moved away from using silver and lead circuitry in satellites. I don't think it would self weld.
I’ve never heard of that.
I have heard that pure gold powder can be cold pressed into an ingot. But I’ve never tried it.
@@sreetips We are all waiting for you to try it.
Why are you using Nitric acid instead of Acid/Peroxide? AP can be regenerated indefinitely and reacts less with the Gold. (Gold is slightly soluble in Nitric Acid which is how Aqua Regia works). You used about 2 liters of Nitric acid which costs about $30. AP would cost about $3.
He has in a previous video, but I don't remember if he explained why he doesn't use it. Perhaps his source is more scarce?
@@nunyabisnass1141 Fair enough. I use 40% peroxide from hydroponic stores to keep the dilution to a minimum. Maybe that is his reason
@@WarkWarbly I missed that. That much Nitric is a big cost but I guess it is the cost of business. I use Iodine to strip Gold plate and the startup cost is really high but it is easily regenerated.
he doesn't it that way because he says it takes too long. I tried to explain it to him if he uses heat or even an air bubbler while doing it, it would take less than 2 days.
him no answer you very error in him work 🤔
precious
What was the total yield? What was the % gold in the scrap? Thank you
17 pounds of scrap yielded 27.3 grams of pure gold over six recovery videos. 17lbs = 7709g so 27.3g pure gold divided by 7709g of computer scrap equals 0.0035 or 0.35%
@@sreetips thank you
In recovery gold from computer scrap you need to be carefully of the presence of tin metal in it, because it's could be reduce the yield. To prevent this you need to submerge the computer scrap to the solder remover solution, HCL would work but it take forever to remove the tin, so i would teach you how to make the solder remover first disolve 15 gram of urea in 30ml of hot water then add 21ml 68% conc nitric acid to it then swirl it it would form a white crystal of urea nitrate which is high energetic material so becarefull with ATF, then add 800ml of distiled water and mix until the urea nitrate disolve, add 50g of citric acid to the water, last add 200ml 50% conc nitric acid to the solution and mix. Sreetips i request you make a video more often about recovery gold from computer scrap because it would be a great topic on your chanel, thank you.
These trimmed fingers were very clean. The seller did a nice job of clipping them real close. I didn’t see any solder (tin/lead) on any of this scrap.
Have you thought about doing a video to separate silver buttons from copper that is used in switches
Yes, I have.
I keep wondering about the history of the chemical process used. Who ever thought that you could dissolve gold into a liquid 🤔
It would've saved alot of robberies in the good-ol-days if they thought the barrel was nothing more than liquid human waste 😂
It in fact did. I can't remember the whole story but somewhere it was used to fool a potential thief.
It worked to pull the wool over the eyes of the nazis. A few noble metals were dissolved in the old royal water and sat on a shelf for the war.
I want to learn how to do this
You just did. :)
BE VERY CAREFUL DOING WHAT SREETIPS IS DOING HEED ALL WARNINGS AT THE BEGINNING OF HIS VIDEOS MICHAEL AT MY NEW HOUSE I WILL BE BUILDING EXACT COPYS OF HIS SILVER CELL TO GROW THE PURE SILVER CRYSTALS 💰💰💰
Beautiful Gold button!👍✨️✨️✨️🏆greetings from the Netherlands mr Sreetips and miss Sreetips👍🇳🇱
Greetings Netherlands
In past videos you broke down the cost vs recovered metal and spot price comparison. Just curious, I’m guessing between chemicals and cost of scrap, I’m guessing it was probably a net loss vs buying at spot price? I get you don’t do this because it’s “easy money” and there is value in recycling and educating folks, plus TH-cam revenue and the ability to sell for a premium since many are willing to pay more because this button has a story, but just curious!
You’re right, it probably is a loss.
Love the video, I have a two part question. How do you measure out the Ferrous Sulfate and the water?
And what is the name of that white item that you placed your melting dish on?
The book calls for a pound of ferrous sulfate for every fifty penny weight. A pound is 453.5g and 20 penny weight is a Troy ounce (31.1 grams) so if I have an ounce of gold (31.1 grams) I’ll use about 200 grams of ferrous sulfate. That amount should dissolve in a half liter of hot distilled water. The white insulation is ceramic wool. Don’t try to use fiberglass. It will just melt and stick to the melt dish. I get ceramic wool at Grainger.com
@@sreetips thank you so much.
That’s some great looking gold. I love it! Where do you get the fingers?
eBay for twenty four hundred bucks
An interesting note.... you Americans call it SMB (Sodium Meta Bi) It is correctly called SMS (Sodium Metabi-Sulphite) weird no??
Yes, that’s very strange. I learned that (SMB) on the forum.
As a winemaker we always called it SMS or PMS (Potassium Meta Bi Sulphite....same thing). Keep up the great work!
