You are the world's leading authority on small scale refining and your dedication to educating in that area is beyond measure.

It sure helped me. All these guys making videos collecting tons of computer pins think they'll are striking it rich, when its really just costing them more money than its worth. I had about the same amount of bars this guy had and here I'm thinking i struck it huge. I watched this and my stomach dropped. I'm just going to give them away now.
I came to see a video because I was thinking of buying some bars and found your wonderfully clear video. I am so very glad! Thank you! You preform a great service! Thank you also to Chris who donated the bars!
I would imagine that if they are able to process all those computer metals, they’d be able to process all the gold out before they send you an ingot of a gold colored alloy.
Your results are exactly what I expected. I feel bad for the people that are stacking these up thinking that they are getting a good deal on recoverable Gold...Ebay scammers suck.
@@woonsockettruthseeker9009 That is not what is happening. What the venders are saying these are (which, at least in this case, is clearly not what is happening) is that this is bars made of melted gold foil pins from e-waste. The people stacking up these bars know that they aren't pure gold, they are thinking they are like 1% gold that they will have to put a lot of time into extracting, but if they can spend $35 on 300 grams of this and get even a gram of gold (currently $65 per gram) it would be worth it. Only the scammers are stright up lying about what the bars are made of.
As long as there are dumb people, there will be scammers preying on them. Everywhere! This is just one of the more obvious examples. Apple users are the same, but they are so naive still thinking they were the ones getting the better end of it. ;)
Thank you both. These videos are worth more than the time it takes to watch them. So I watch some multiple times. You're the Micheal Jordan of UA-cam garage-lab refinery. I could watch gold turn to powder all day, Alchemist.
Dude! You are not just a metal refiner you are also a philanthropist! Because this information is that valuable. I really appreciate it! Thank you again.
Thanks for this video brother. I almost bought some of these to test out my self. Sooooooo glad I didn’t. You are the man. 💪👍🏻keep up the great content, it’s very much appreciated
I think if you process them in a copper sulfate cell at 1-1.5 volts you will have a cheaper method of collecting the copper in those bars. Then the residue ( a bit of Cu, Zn, Ni, Fe, Pb) is easier to dissolve. You then can use H2SO4 or HCl to remove the remainder of the contaminates. Kind of electrowinning the pure copper that you can throw into your waste bucket. I have a Buck converter that takes 5 volts from my computer power supply and drops it to 1 volt. Works well. The big issue you had was brute forcing the dissolution of the major components with Nitric acid. Like you proved to us in the video where you added too much silver, the gold was very finely divided. Some may even passed through the filter paper. All in all an excellent demonstration. Thank you!
You inspired me to start my own at-home, small scale refinery last winter. I spent hours and hours to get my first gram of gold from gold-filled jewelry, but then it got stuck in my melting dish due to an improper borax glazing or lack of heat. I'm excited to try again this winter and just wanted to say thank you for all your education videos. I've watched them for hours and hours to troubleshoot my process and learn what to do.
I got one, had it tested it came back "unknown, likely brass." I sent it back for a refund and reported my findings on the review. I lost $15, for potage and curiosity 8/.
I have to admit I was excited with your ebay purchase and then it was a lunchbox let down. I can't put a price on the knowledge I'm gaining from watching your videos. Thank you so much for all the education. I am nowhere near ready to start refining but I'm gaining the knowledge to start. My biggest concern is safety and then it's finding the scrap at the cheapest possible price so that my only expense will be the overhead and the acids. Nitric is so expensive (in the range of $100 PER LITER). I need to find a cheaper source for acids. Thank you for taking the time to shows us all.
This is the reason why i study metal refining and recovery. I usually doubt those gold looking for sale to be gold. I never bought any gold yet aside from our wedding rings. instead of buying i started doing small scale processing to get real gold. I am learning from your videos Sir. Thank you! as always stay safe! 😊
Solid snake oil, gotta give it to them sellers they are making money of scrap recovery by processing the precious metals themselves and selling the dregs to others ingenious (ofc its disingenuous).
You'll notice they're almost exclusively from 1srael, the same people have multiple accounts with feedback under 1k, and they all have 100% positive feedback scores. Do they have 100% happy customers? Is this more likely some kind of money laundering operation?
Unfortunately, these bars are still being sold on Ebay almost 5 years later. I seen some on Ebay and thought to myself that something about them didn't seem right. Mainly the price. Glad your video is still up.
Great video. Your whole video collection is excellent. Thanks for sharing your knowledge and expertise! I wish I had watched this video before buying 250g of that stuff. It just disappeared completely in nitric acid (lots of acid and many hours). Beautiful blue solution with some white residue (titanium?). Looking at the low price and their free shipping to New Zealand, I didn't expect much gold. But I did hope to get a gram or two. After all, they call it "scrap gold bar for gold recovery". There were a few milligrams of gold particles mixed with that white residue. Very difficult to filter. I ran a fraction of the filtrate through a 0.45 micron filter. I though perhaps the gold is suspended in very fine particles. The filter turned slightly yellow, but it can't have been more than a few micrograms. There wasn't any silver either. They do have a disclaimer "it is not solid gold". But it certainly isn't fit "for gold recovery" either. Isn't that a scam?? You can only use it to impress or fool your friends.
The white residue is likely tin. These bars are probably melted plumbing fittings, and the plumbing solder contains tin. Tin reacts with nitric acid to produce a white sediment that is insoluble in nitric, water, nor pretty much anything else. The yellow on your filter was likely traces of iron that were in the fittings or ingot mold.
So here is a hilarious story I have melt bars like this coming and I was at the coin shop when they where delivered. I got home a few hours later and someone stole it. I hope they have fun with their zero content gold!
I've been considering this for a while. So a quick search for videos brought me to yours. I figured there wasn't a LOT of gold in them, but I expected SOME. I'd be annoyed if I PAID for those bars, spent $20 on gas and $100 on Nitric Acid to melt a brass coated lump of iron. Thanks to you I'll steer clear of these! Cheers.
I think he used about $20 worth of nitric to dissolve the bars plus a lot of time! I checked those eBay "melt drop" listings sometime ago and passed. I purchased some silver grain listed as, "Sterling Silver" casting grain 8 years ago from an eBay seller. I processed it and it was not %92.5 silver. It was %80 silver.
ALWAYS be careful, this is why I approve of hallmarking. Not a publicity statement, but all my silver and gold are hallmarked 999 by the Edinburgh assay office
Really Precious Man ! ! ! Your teachings are priceless , your videos are superb , viewers are privileged with true knowledge. Thank you. Thank you. Thank you.
Judging by all the reactions and your findings you got a lot of Nordic Gold. 89% copper, 5% aluminium, 5% zinc, 1% tin. Has gold in the name as it was and still in use with Euro currency but is just a copper alloy mix that gives it the appearance of Gold
BigstackD has made a lot of Nordic Gold videos to where anyone can identify it. Plus, the way those bars rang out when clanked together said 'not gold'.
@@sreetips I was already suspicious about the scrap gold, some ppl do sell high yield scrap gold 80 percent yield or more bt I know not common. Obviously the ones on Ebay deserve more scrutiny.
I was just looking at these bars and contemplating buying a few then I decided to search for some videos on it. Saved me some money, frustration and chemicals. Thanks sreetips.
Omg. Thank you so much for this video. It's so easy to get screwed over these days. Thank you sir. I appreciate all your time your out into that. Thank you for educating us.
Your video is the proof of the saying "There's a fool born every minute". I would recommend that if anyone is considering buying any of these bars, they should definitely watch your video first. 👍👍
The water provides a medium for the metals to dissolve into. You could use just liquid dish soap to clean your hands. But it works much better if you add some water.
Man I am finally glad I found this video in your inventory. This answers my question about the refining process that I ask you from the other video. Too bad I didn’t find your channel before I bought my stuff from eBay. I’m going to guess your findings will be very similar across-the-board. You areToo bad I didn’t find your channel before I bought my stuff from eBay. I’m going to guess you’re findings will be very similar across-the-board. You are very knowledgeable and put out excellent video. Keep up the good work.
I know this is an old video, but I’m curious, did you ever put copper in the nitric that you poured off to see if any silver would cement out? I know that would have eventually happened in the stockpot, but I was wondering if you tried to cement it out separately to see if there was any silver yield. I only ask out of curiosity because I have ZEE-row interest in wasting my nitric to investigate 😂
Given the very low (essentially nil) concentration of gold and the fact that it went to basicly a colloidial suspension due to the fineness of the particles, would it be beneficial to remelt and create new shot when say 20% of the original weight is remaining? then maybe again when down to 5%.?
Thanks for sharing. You and your wife remind me of my Late Uncle Glen and Aunt Jill. I love the refinery concept it is amazing. I have all of the chemicals my self to refine gold. Nitric Acid was hard to come by over here and very expensive. 500 ml for almost $100.00 usd. I found an excellent person on eBay that sells gold bars and it is real gold. (If the CPU's are gold then the CPU gold bars made from them are gold too its that simple) But lets not forget All the Gold and Silver is mine saythe the Lord.
Thanks for this video and thanks to the person who provided the material to attempt to refine. Too bad there isn't a way to warn potential scam victims. And eBay policy let's scammers do this BS. Thanks for the always accurate scientific method approach of all your refining. With your no nonsense just straight facts proven by experimentation process of showing others how to do this, I have gained much knowledge that I don't have to question further. It is very much appreciated. Thanks for your awesome videos.
Hey..if there was no gold to be found it wasn't through lack of trying. You done all you could. Its a shame to waste your time really but you provide valuable lessons for the world Thanks for that.
hello Sreetips, do these bars also depend on what type of computer pins and other mixed alloys are cast into bars? i bought 1959 g a few years back but never get the time to do it. i rather save my nitrite acid for the real nuggets. thanks for your time and insight. bob
Hello Sreetips, very amusing clip, thanks for that.The best gold yield is from the ground,only elbow grease expended,and I am sure it's around 90% fine,regards George
Sir you have no idea how thanful i am you made this video. I have about the same amount of gold bars you did but i have no idea how to perform the whole refining process. Now I know not to even bother, ill just hand them out to the kids to play treasure hunt games or something. You saved me a whole mess of time. Here I thought I had something big but nope.😂😂
I don't understand the processes, so it's very helpful when you do the voiceover explanations in your video. It's also appreciated that you speed up some of the processes in order to keep the videos at a manageable length. Thanks for the vids and I hope that you pass 70K subs soon.
All I know is I'm very thankful for guys like you to look out for the rest of us that are learning and developing our skills can't believe the capacity of some people nowadays and what they try to get away with thank you for your research and good looking out brother
Hey when i refine pc rams i put nitric and muriatic into a flask that has all the gold flakes from the pc rams. Then after it all dissolves i pore through filter. Then i take urea aand ad it till it stops bubbling, then add SMS and wait for the gold to return as a black powder. What trying to say is did you poor out all if any, gold that would have been in the blue liquid? FYI I refined an oz last year this way. But it took a half a gunny sack of rams to get that oz.
The reaction tells me those bars are aluminum bronze made from refiner waste by cementing out copper from acid with aluminum and then smelting. The small amount you found was because the copper aluminum mess was thrown in The crucible wet. Good work love your videos
I'm a beginner at buying gold and silver and I saw that on eBay and was curious and I'm glad I came across your video. Very informative very interesting it was great content.
"What that tells me is...." ... I need to start selling gold recovered from computers... on ebay! There is a sucker born every minute! Glad you got that stuff for free!
@@sreetips Hmm. I just found this video in your past video playlists, the day AFTER I bought a $49 380gram bar from israel... Ah well, I'll be able to play around and have fun. What I REALLY started watching gold recovery for is crushed quartz hardrock and black sands pan concentrate chemical refining of gold. Theres gold in the streams around me, but not enough to pan well... I got distracted with all those pretty bars or carat scrap refinery and shiny beads of car cat platinum. Something to play with and practice on at least. I'll just have to dial it down from recovering a little gold to recovering copper :D
There was a tiny bit of gold that formed a light dusting on the bottom of the beaker the next morning - not enough to get a weight and calculate a yield though
@@sreetips well I had expected to get Maybe $5 from my investment of $50, it was the experience and experiment more than anything. I guess I just have to roll that back from $5 out of $50 to 5c out of $50. No counting chemical consumption.
1% tin would mean about two grams of tin in my 211 gram batch that I processed. Two grams of tin in nitric acid would form tons of metastannic acid. Metastannic acid is the consistency of Elmers glue. That much tin would instantly glog the filters. I didn't see any tin in there, mostly brass.
@@sreetips As I remember, the first step was dry weight. Then suspend a beaker full of water, with a catch pan under with a known weight. Carefully lower the unknown in suspended by fine string. Catch the water it displaces and weigh it. 1 cc is 1 gram so the weight in grams equals the cc of the bar. Now you know grams per cc. Compare it to a known sample of gold.
Bummer, I thought there was going to be a lot more then that in those bars. I remember you showing these bars in a previous video and I was so anxious for you to make this video. Oh well... thank you for doing this experiment, at least now we all know what to expect if we decide to buy these bars.
I bought some trimmed circuit card fingers once. The seller actually told me, "you're going to make lots of money with this scrap." He didn't know that I had experience with it and already knew that it would be a loss. They are betting on the buyer of the over priced scrap to be to embarrassed to speak out after getting ripped off.
@@sreetips I am currently mining my own coin pins from electronic circuit boards - I never did this before and I don't know what the end result will be - but I do know that I have spent zero (0) dollars in recovering my dead electronics - an Urban Miner needs to be creative to minimize cost. I have spent about 50 hours of my time and I have recovered 207 grams of gold plated source material. Thanks for youe videos - they are awesome - Jack
I had some of those analyzed and got 2% gold. Without inquarting I’m told the gold would be colloidal (at a percentage less than 25% hence the need to inquart aside from passivation) and pass right through the filters. Also, wouldn’t colloidal gold give a negative stannous test. Honest question; I truly don’t know. If so, definitely NOT enough to be worth the purchase, but just wondering. Plated pins would be extremely low percentage and the copper melted with it would give it a golden color. That might be consistent with your less than 2/10ths of 1 gram? (Btw, 2% was probably a Better than average batch).
Thanks for this video! I was looking at those same kind of bars last night on ebay do try this same thing. You saved me some money and time. Thank you sir!
i guess the original bars will also stick to a magnet, but the seller would likely attribute that to impurities. how about to measure mass & volume, would that be quicker vs nitric acid?
Just an idea, but have you thought aboit doing the reactions with nitric acid in them in a flat bottom flask with a distillation setup on them to recapture and distill the reaction gasses and refill your nitric acid bottles?
Wouldn't dissolving the metal with aqua regia (1:3 nitric acid to hydrochloric acid) then pushing the gold out of solution with sodium metabisulfite be more material efficient in the process of gold recovery?
I was thinking the same thing. Wonder if he had already judged that it probably had very little silver in it and it wouldn't be worth it. But damn, what a waste of HNO3! It's getting costly to come by nitric acid these days.
Beads are used in some older catalytic converters. They can be replaced by unscrewing a metal plug in the cat, dumping out the old catalyst, pouring in fresh beads. The beads that I used in the video are not very common. I was lucky to find them on eBay. I think that I paid $179 USD for them.
I have 8 catalytic converter .i used 2 cats used for refining but i can't reaches desired result .i was test it with stannous chloride solution but there was little bit yelloesh colour which is not inuf .please guide me how can i do that process .if u have any video or voice callung apps we use that for chatting
if those bars were 1% gold then I would have gotten about two grams of pure gold from the 211 gram batch worth about $80 USD. But I don't think that a 1% gold content would show up on a touch stone test. The only way to do this, that I could see, is refining with a wet chemical process.
6'40" I also think there was some zink in the alloy cause when you made the shot white smoke was coming from the crucible. When it is really dense the Zink vapours can also get yellowish.
@sreetips Clearly. You've inspired me to do my first attempts with refining so I really appreciate your content especially on your cell videos. Watching them is gold all on its own.
This would have produced silver chloride in solution from the solder left over from the pins if there was any. Along with he may have been "hopeing" that there was gold and it would be been in vain if it was
@@aaronreash814 ok but recovering the silver he could realloy the metals that did not dissolve and the silver to continue on. Removing copper iron tin zinc etc and getting them out of your way can only be a bonus. Remember to begin with he was unsure of the composition of the ingot. Start cheap.
We get up before dawn and go to yard sales. Arrive 3 hours early at estate sales to be first in line. Otherwise the jewelry gets snapped up and we get nothing. Consignment stores, resale shops and thrift stores. It’s out there, but it won’t fall in your lap. Most important: learn how to spot and exclude fake stuff - that takes years of experience. There’s no substitute for experience.
cool very decent info tho too bad 500ml of nitric get wasted tho we all learn somethings thanks for your time you put into making those vids sir and have a good one👍👍👍😀👍👍👍
Those gold bars that they sell on eBay are for making jewelry or crafts, to achieve gold-colored pieces. If you read the product specifications, it warns you. This metal is composed of 66% Copper and 34% Brass.
Great video. Recently, very recently I saw these bars on eBay and smelled BS. There is no way that they could contain more than trace amounts of gold I was thinking. I even emailed FIVE of the scheisters selling this "fool's gold" and NOT ONE returned my detailed inquiry. I still have them in my send box so I am sending them the video and also complaining to eBay, even though I did not buy any bars since it was obvious. I hate when scammers get on the site. It undermines the credibility of good sellers and tarnishes all of the sellers IMHO.
I figured that those were just an alloy that had a gold color to then because I have a 29lb ingot of real smelted pentium pro cpus and it is copper colored because there is so much more copper than good in the metals contained in them. I need it refined but it would use so much nitric that it would cost a ton. I am trying to figure out the best method of electrolytic refining technique that would work best. Any help would be appreciated. It's a ingot straight from the crucible because they crushed about 180lbs ceramic cpus then fluxed out the ceramic and alot of the base metals and was left with a 29lb ingot of the pms .
Thanks for the reply. sorry for the confusion. allow me to rephrase. What did you buy? My question was regarding the original composition of the bar you purchased- not the solution. @@sreetips
Sorry, I was referring to a different video. These bars were donated to me by a viewer. But people do buy stuff like this thinking it’s gold. It’s not, or it may have traces. They pay forty bucks plus shipping for two dollars worth of metal. I recently had a gentleman ask me to verify the silver content in a coin he purchased online. It was $28 per coin, buy one, get one free. So $14 per coin. He thought he’d found a way to get rich with current spot silver at $22. He actually believed that a seller would give silver away like that. I explained that there’s no need to test it. It had the odor of a scam with those prices.
You are the world's leading authority on small scale refining and your dedication to educating in that area is beyond measure. Your willingness to demonstrate processes like this and prove that they aren't worth the trouble has likely prevented untold numbers of less than well informed individuals from rushing into action and hurting themselves or others or the environment.

Judging by all the reactions and your findings you got a lot of Nordic Gold. 89% copper, 5% aluminium, 5% zinc, 1% tin. Has gold in the name as it was and still in use with Euro currency but is just a copper alloy mix that gives it the appearance of Gold
This was my first thought. Either Nordic Gold or some aluminum/bronze alloy.
That's exactly what it is
That is exactly what I was thinking also.
BigstackD has made a lot of Nordic Gold videos to where anyone can identify it. Plus, the way those bars rang out when clanked together said 'not gold'.
This is so important for ppl to know and il be sharing this video all over the net 🤗
This guys are making a fortune off people’s misunderstanding.
@@sreetips I was already suspicious about the scrap gold, some ppl do sell high yield scrap gold 80 percent yield or more bt I know not common. Obviously the ones on Ebay deserve more scrutiny.
Would you be willing to share where you source your nitric acid?
Gfs chemicals
I was just looking at these bars and contemplating buying a few then I decided to search for some videos on it. Saved me some money, frustration and chemicals. Thanks sreetips.
Thank you, it's the reason I made the video.
From what I was taught, gold in computer components is layered at an atomic level and only in certain parts at certain points.
Omg. Thank you so much for this video. It's so easy to get screwed over these days. Thank you sir. I appreciate all your time your out into that. Thank you for educating us.
Your video is the proof of the saying "There's a fool born every minute". I would recommend that if anyone is considering buying any of these bars, they should definitely watch your video first. 👍👍
I've been watching you a long time and you are certainly knowledge and I like how you show the whole process in your video's with nothing hidden.
This was almost sad to watch. Oh well, good job!
Just think of the guy who paid $179 for 1700 grams of this junk.
So why did you have to keep adding water with the acid?
New subscriber here!
The water provides a medium for the metals to dissolve into. You could use just liquid dish soap to clean your hands. But it works much better if you add some water.
Thank you!
Can you XRF one or a couple to determine what the % of base metals show. I would be interested in knowing bud
I'll see what I can do.
@@sreetips just curious, great vid bud.
Nordic Gold is an alloy composed of 89% copper, 5% aluminum, 5% zinc, and 1% tin.
Man I am finally glad I found this video in your inventory. This answers my question about the refining process that I ask you from the other video.
Too bad I didn’t find your channel before I bought my stuff from eBay.
I’m going to guess your findings will be very similar across-the-board.
You areToo bad I didn’t find your channel before I bought my stuff from eBay.
I’m going to guess you’re findings will be very similar across-the-board.
You are very knowledgeable and put out excellent video. Keep up the good work.
I really like how you went all the way through the reactions.
I know this is an old video, but I’m curious, did you ever put copper in the nitric that you poured off to see if any silver would cement out?
I know that would have eventually happened in the stockpot, but I was wondering if you tried to cement it out separately to see if there was any silver yield.
I only ask out of curiosity because I have ZEE-row interest in wasting my nitric to investigate 😂
No, I didn’t
I for days was contemplating on buy a few of them bars. Not now!!! Thank you for saving me money, time, and whole lot of aggravation.
I made this video specifically for people like you. The sellers of these bars are ripping people off.
Thanks for sharing this very important work it's good to know what to look for
Given the very low (essentially nil) concentration of gold and the fact that it went to basicly a colloidial suspension due to the fineness of the particles, would it be beneficial to remelt and create new shot when say 20% of the original weight is remaining? then maybe again when down to 5%.?
Thanks for sharing. You and your wife remind me of my Late Uncle Glen and Aunt Jill. I love the refinery concept it is amazing. I have all of the chemicals my self to refine gold. Nitric Acid was hard to come by over here and very expensive. 500 ml for almost $100.00 usd. I found an excellent person on eBay that sells gold bars and it is real gold. (If the CPU's are gold then the CPU gold bars made from them are gold too its that simple) But lets not forget All the Gold and Silver is mine saythe the Lord.
Thanks for this video and thanks to the person who provided the material to attempt to refine. Too bad there isn't a way to warn potential scam victims. And eBay policy let's scammers do this BS.
Thanks for the always accurate scientific method approach of all your refining. With your no nonsense just straight facts proven by experimentation process of showing others how to do this, I have gained much knowledge that I don't have to question further. It is very much appreciated. Thanks for your awesome videos.
They already look like some cool gold bars as they are,never seen these before,very cool.
Hey..if there was no gold to be found it wasn't through lack of trying. You done all you could. Its a shame to waste your time really but you provide valuable lessons for the world
Thanks for that.
hello Sreetips, do these bars also depend on what type of computer pins and other mixed alloys are cast into bars? i bought 1959 g a few years back but never get the time to do it. i rather save my nitrite acid for the real nuggets. thanks for your time and insight. bob
Bob, they are a complete rip off. The amount of gold, if any, is minuscule.
i am curious about the other metals in the Nitric Acid. What if anything can you recover of copper and other materials from the liquid?
I don’t know
Hello Sreetips, very amusing clip, thanks for that.The best gold yield is from the ground,only elbow grease expended,and I am sure it's around 90% fine,regards George
Sir you have no idea how thanful i am you made this video. I have about the same amount of gold bars you did but i have no idea how to perform the whole refining process. Now I know not to even bother, ill just hand them out to the kids to play treasure hunt games or something. You saved me a whole mess of time. Here I thought I had something big but nope.😂😂
Excellent, thank you
I don't understand the processes, so it's very helpful when you do the voiceover explanations in your video. It's also appreciated that you speed up some of the processes in order to keep the videos at a manageable length. Thanks for the vids and I hope that you pass 70K subs soon.
Do they sell nitric acid in larger quantities for you? Seems like you would benefit by buying in like 50 gallon drums.
All I know is I'm very thankful for guys like you to look out for the rest of us that are learning and developing our skills can't believe the capacity of some people nowadays and what they try to get away with thank you for your research and good looking out brother
Hey when i refine pc rams i put nitric and muriatic into a flask that has all the gold flakes from the pc rams. Then after it all dissolves i pore through filter. Then i take urea aand ad it till it stops bubbling, then add SMS and wait for the gold to return as a black powder. What trying to say is did you poor out all if any, gold that would have been in the blue liquid? FYI I refined an oz last year this way. But it took a half a gunny sack of rams to get that oz.
No, there wasn’t much gold in those bars to begin with
The reaction tells me those bars are aluminum bronze made from refiner waste by cementing out copper from acid with aluminum and then smelting. The small amount you found was because the copper aluminum mess was thrown in The crucible wet. Good work love your videos
I'm a beginner at buying gold and silver and I saw that on eBay and was curious and I'm glad I came across your video. Very informative very interesting it was great content.
Welcome!
"What that tells me is...." ... I need to start selling gold recovered from computers... on ebay!
There is a sucker born every minute! Glad you got that stuff for free!
At least folks have a place to look BEFORE going out and spending their hard-earned money on this worthless scrap.
@@sreetips Hmm. I just found this video in your past video playlists, the day AFTER I bought a $49 380gram bar from israel...
Ah well, I'll be able to play around and have fun. What I REALLY started watching gold recovery for is crushed quartz hardrock and black sands pan concentrate chemical refining of gold. Theres gold in the streams around me, but not enough to pan well... I got distracted with all those pretty bars or carat scrap refinery and shiny beads of car cat platinum.
Something to play with and practice on at least. I'll just have to dial it down from recovering a little gold to recovering copper :D
There was a tiny bit of gold that formed a light dusting on the bottom of the beaker the next morning - not enough to get a weight and calculate a yield though
@@sreetips well I had expected to get Maybe $5 from my investment of $50, it was the experience and experiment more than anything. I guess I just have to roll that back from $5 out of $50 to 5c out of $50. No counting chemical consumption.
Thank you just saved me some money there 🙏
Probably Nordic gold (alloy).. Nordic gold also contains 1% Tin... would that be a problem for the stock pot?
1% tin would mean about two grams of tin in my 211 gram batch that I processed. Two grams of tin in nitric acid would form tons of metastannic acid. Metastannic acid is the consistency of Elmers glue. That much tin would instantly glog the filters. I didn't see any tin in there, mostly brass.
@@sreetips bad gold yield but gained knowledge is more worth than gold. I like the evaluations.
You are awesome! Wow! Extremely professional and thorough.
melting of the pins is a bad idea anyway. Layer of the gold on them is very thin, and significant amount of gold will simply evaporate, while melting
Do you think there's another way to process the pins, then? Be a shame to waste the gold
I remember a 1970's school project. An alloy of gold and copper. We weighed the water it displaced to calculate specific gravity.
Didn’t that require perfect dimensions of the bar?
@@sreetips As I remember, the first step was dry weight. Then suspend a beaker full of water, with a catch pan under with a known weight. Carefully lower the unknown in suspended by fine string. Catch the water it displaces and weigh it. 1 cc is 1 gram so the weight in grams equals the cc of the bar. Now you know grams per cc. Compare it to a known sample of gold.
Bummer, I thought there was going to be a lot more then that in those bars. I remember you showing these bars in a previous video and I was so anxious for you to make this video. Oh well... thank you for doing this experiment, at least now we all know what to expect if we decide to buy these bars.
Thank you for this video - you are the Myth Buster of this scandalous gold recovery industry - honesty is veryhard to find.
I bought some trimmed circuit card fingers once. The seller actually told me, "you're going to make lots of money with this scrap." He didn't know that I had experience with it and already knew that it would be a loss. They are betting on the buyer of the over priced scrap to be to embarrassed to speak out after getting ripped off.
@@sreetips I am currently mining my own coin pins from electronic circuit boards - I never did this before and I don't know what the end result will be - but I do know that I have spent zero (0) dollars in recovering my dead electronics - an Urban Miner needs to be creative to minimize cost. I have spent about 50 hours of my time and I have recovered 207 grams of gold plated source material. Thanks for youe videos - they are awesome - Jack
Who knows how many hundreds of thousands of Dollars you will eventually save your fellow man! A great service to all! Thank you.. Dan
So what do you think the metal actually is in these "melt drop bars"? Iron? With a little copper, brass, and zinc?
Mostly brass
thank you for being honest and preventing others from making a mistake
Thanks for doing this. I always had these recommended on eBay and I was wondering what they were really like.
I had some of those analyzed and got 2% gold. Without inquarting I’m told the gold would be colloidal (at a percentage less than 25% hence the need to inquart aside from passivation) and pass right through the filters. Also, wouldn’t colloidal gold give a negative stannous test. Honest question; I truly don’t know. If so, definitely NOT enough to be worth the purchase, but just wondering. Plated pins would be extremely low percentage and the copper melted with it would give it a golden color. That might be consistent with your less than 2/10ths of 1 gram? (Btw, 2% was probably a Better than average batch).
No way that there's 2 grams per 100 grams of this metal. No way.
Thanks for this video! I was looking at those same kind of bars last night on ebay do try this same thing. You saved me some money and time. Thank you sir!
Excellent, they’re a ripoff.
i guess the original bars will also stick to a magnet, but the seller would likely attribute that to impurities. how about to measure mass & volume, would that be quicker vs nitric acid?
Would cupelling the gold remove a lot of base metals?
I am really enjoying these videos. They are starting to become a highlight to my day whenever I get a notification.
Just an idea, but have you thought aboit doing the reactions with nitric acid in them in a flat bottom flask with a distillation setup on them to recapture and distill the reaction gasses and refill your nitric acid bottles?
Wouldn't dissolving the metal with aqua regia (1:3 nitric acid to hydrochloric acid) then pushing the gold out of solution with sodium metabisulfite be more material efficient in the process of gold recovery?
Eric - each refining will require adjustments based on what metals were are trying to separate.
Brilliant video streetips. It would be good to chuck some copper in your waste ts see if you get any silver cementing out.
I was thinking the same thing. Wonder if he had already judged that it probably had very little silver in it and it wouldn't be worth it. But damn, what a waste of HNO3! It's getting costly to come by nitric acid these days.
Thanks for your video, it changed my mind on purchasing any of it on EBay.
It's essentially nordic gold, copper mixed with aluminum, zinc, and tin.
Wow you can really hear the difference in the sound of the metal clanking together versus something that contains gold or platinum
Is beads compulsory to add in catalytic converters ?? Please guide me .thanks
Beads are used in some older catalytic converters. They can be replaced by unscrewing a metal plug in the cat, dumping out the old catalyst, pouring in fresh beads. The beads that I used in the video are not very common. I was lucky to find them on eBay. I think that I paid $179 USD for them.
I have 8 catalytic converter .i used 2 cats used for refining but i can't reaches desired result .i was test it with stannous chloride solution but there was little bit yelloesh colour which is not inuf .please guide me how can i do that process .if u have any video or voice callung apps we use that for chatting
It's too complex for me to guide you. I demonstrate the process in a video; ua-cam.com/video/ryQrBWbDz78/v-deo.html
You just save so many people so much money man you're like a hero.
There must gold. It's yellow! LoL
15:23 gold bar 🤣 Good job man! 😁
Wouldn't an acid test on a stone given you any indication, prior to the dilute nitric acid process?
if those bars were 1% gold then I would have gotten about two grams of pure gold from the 211 gram batch worth about $80 USD. But I don't think that a 1% gold content would show up on a touch stone test. The only way to do this, that I could see, is refining with a wet chemical process.
6'40" I also think there was some zink in the alloy cause when you made the shot white smoke was coming from the crucible. When it is really dense the Zink vapours can also get yellowish.
There was yellow residue on my graphite stirring rod when I got done stirring the molten metal.
@@sreetips Aah yes...that's probably from zink.. It's also terrible when welding galvanized steel.
Thank you. I really appreciate this video. I was considering doing this until I stumbled upon this video. You are an amazing teacher. Thank you again.
They are a rip off
@sreetips Clearly. You've inspired me to do my first attempts with refining so I really appreciate your content especially on your cell videos. Watching them is gold all on its own.
Thank you for taking the time to make this video. You just saved me a bunch of money!
Wouldn't it have been prudent and tremendously cheaper to soak those ingots in HCL first?
This would have produced silver chloride in solution from the solder left over from the pins if there was any. Along with he may have been "hopeing" that there was gold and it would be been in vain if it was
@@aaronreash814 ok but recovering the silver he could realloy the metals that did not dissolve and the silver to continue on. Removing copper iron tin zinc etc and getting them out of your way can only be a bonus. Remember to begin with he was unsure of the composition of the ingot. Start cheap.
@@joerowland607 that is true! I'll give you that. All and all he should have done a sp. grav to begin for cost that would tell hey it's most copper.
Copper won't dissolved in HCl, unless you add hydrogen peroxide to it or bubble air through it.
Question, did you use any copper to see if any silver dropped out?
No
I'm new to your channel an I was wondering how to go about getting scrap jewelry and other ways of doing it please and thank watch all your videos
We get up before dawn and go to yard sales. Arrive 3 hours early at estate sales to be first in line. Otherwise the jewelry gets snapped up and we get nothing. Consignment stores, resale shops and thrift stores. It’s out there, but it won’t fall in your lap. Most important: learn how to spot and exclude fake stuff - that takes years of experience. There’s no substitute for experience.
cool very decent info tho too bad 500ml of nitric get wasted tho we all learn somethings thanks for your time you put into making those vids sir and have a good one👍👍👍😀👍👍👍
Those gold bars that they sell on eBay are for making jewelry or crafts, to achieve gold-colored pieces. If you read the product specifications, it warns you. This metal is composed of 66% Copper and 34% Brass.
Thank you for saving us beginners a whole lot of money and gold dreams
I bet they held back most of the gold-plated material, and whatever gold plated thing it was that snuck in, wasn't trimmed very well.
Great video. Recently, very recently I saw these bars on eBay and smelled BS. There is no way that they could contain more than trace amounts of gold I was thinking. I even emailed FIVE of the scheisters selling this "fool's gold" and NOT ONE returned my detailed inquiry. I still have them in my send box so I am sending them the video and also complaining to eBay, even though I did not buy any bars since it was obvious. I hate when scammers get on the site. It undermines the credibility of good sellers and tarnishes all of the sellers IMHO.
I may do an updated video on these.
I figured that those were just an alloy that had a gold color to then because I have a 29lb ingot of real smelted pentium pro cpus and it is copper colored because there is so much more copper than good in the metals contained in them. I need it refined but it would use so much nitric that it would cost a ton. I am trying to figure out the best method of electrolytic refining technique that would work best. Any help would be appreciated. It's a ingot straight from the crucible because they crushed about 180lbs ceramic cpus then fluxed out the ceramic and alot of the base metals and was left with a 29lb ingot of the pms .
Cut a small chunk off and boil in hot dilute nitric to see what you get. Experiment.
I've been watching your videos for a while now and have not been disappointed yet
So it was iron, and what was the yellow color- Copper? and what other metal to make it not corrode- Nickel? curious
Copper in solution is blue. Gold in solution is yellow (so is iron). Blue and yellow make green.
Thanks for the reply. sorry for the confusion. allow me to rephrase.
What did you buy?
My question was regarding the original composition of the bar you purchased- not the solution. @@sreetips
Sorry, I was referring to a different video. These bars were donated to me by a viewer. But people do buy stuff like this thinking it’s gold. It’s not, or it may have traces. They pay forty bucks plus shipping for two dollars worth of metal. I recently had a gentleman ask me to verify the silver content in a coin he purchased online. It was $28 per coin, buy one, get one free. So $14 per coin. He thought he’d found a way to get rich with current spot silver at $22. He actually believed that a seller would give silver away like that. I explained that there’s no need to test it. It had the odor of a scam with those prices.
On an unknown alloy of electronic scrap, to save time and chemicals, use an XRF gun to determine the quality and quantity of any precious metals
Just have to wonder if he’d have filmed the hat eating portion! LOL
