Just to let you know, I have learned more from watching you work with chemicals and their reactions with metals than I did in chemistry, which I failed. You make it fun.
Chemistry in the hands of an uneducated or unpracticed individual who possesses no ability whatsoever to generate at least a general mathematically predictable outcome is dangerous. Glad your okay. And your show is fascinating. As I’ve said before, you are artful, your methods aren’t experiments, they are tested and proven methods. It’s an awesome show. I’m mesmerized by each installation.
Sir,great job showing whats necessary to do this in a safe way and to show others what the real dangers are.You are a pro chemistry person,You show your experience by the way you handle the chemicals and the equiptment and the lab is clean and safe...be careful....Thanks WCH
@@stylenbeauty he literally just showed you in the video lol. but it's not as easy as the videos make it look. you deal with acids and melting metals, and you need to get that scrap for free or it ain't worth your time. if you get into that, you'll likely be competing with non-profit organizations in your area
Style N Beauty not just gold... platinum, barium, gallium, copper, selenium, iron, aluminum, cobalt, silver, zinc... and a lot of more different metals.
It seems likely that the constant addition of air to the solution didn't help things on the ultrasonic side of it either. Degassing is pretty essential for effective ultrasonic cleaning. From what I've read, placing parts in a beaker in the cleaner is a fairly common practice, especially when you want to clean with a solvent.
This info is still relevant to removing the metals from fingers. Glad this is still up to watch. So glad you we talking near the end of the video. I like you newer videos where you talk about what you are doing. Easier to follow along too.
I see that this method is far less time consuming than the other method. Plus, it looks like you've spent less in overhead. I really enjoyed watching this. Thanks.
That bead weighed about 2 grams which is worth almost $120 US dollars today. I just question how much gas it took to get to that point...oxygen and acetylene gasses are expensive. Even running that torch for ten minutes might eat a large portion of the profit up. Muriatic acid is relatively cheap though and most of his shop expense has probably paid for itself over time.
Chemical experiments look like a fun hobby. Although you seem to spend more than you make but most hobbies usually are expensive. Being that you need chemistry equipment, chemicals(some very expensive), and safety gear it's pricey. Yet over time and enjoyment if you keep making those golden grams it may build an alright nest egg. Price for gold may increase substantially at any time. Experiments and trial and error just may have you find a method that does truly only take 1/2 hour then your hobby will be a gold mine. Thanks for the video. Keep em coming.
Thanks for another great video. For the past three years I have been collecting e-scrap and during that time I must have watched hundreds of videos on gold recovery. So I felt ready to try some. But I made a problem for myself, which I hope you can help with. Chemists in my part of the world sell H202 only in very small amounts at huge prices (€3.50/100ml). I figured I need about one litre for the more than one Kg of ram fingers in AP. Next best option was to go to a hairdresser supplier. Got 1L for €3.70. Poured 4L HCL, then added all the peroxide. Air pump was on already. That was when the fun started! The peroxide must have soap in it or something, as this lot started to foam and boil over (no heat applied). I put an inverted bucket over this lot mainly to protect my animals, then turned the water hose on to it to wash away the boil-over foam as fast as it comes out. After a while it stopped boiling and it is just bubbling from the air pump. What now?
I've never had that happen. I don't have any experience to share. I bought my H2O2 at our local drug store, it's 3% and works ok. It's always best to do reactions with the vessel inside a catch basin or casserole to contain any boil overs.
Thanks. Yes, I was an idiot. Long ago I resolved to follow you guys' advice and always use a catch basin and then I go and leave it out. I thought it had stopped boiling over, so I left the pump running over night. Another big mistake, as this lot kept on making more foam, while some gold started coming off and going with the foam on to the ground and mud (it's raining). Now it's a struggle to pick up those tiny bits of gold.
Ultrasound doesn't "like" to change media. So assuming the transducer is coupled to the stainless steel pan the ultrasound would have to travel through the water then through the glass of the beaker then into the acid. That is three changes of media. With each change the strength is attenuated or lost. Try again using the cleaner's pan as the reaction vessel.
Consider using the ultrasonic as a better way of stripping the strips of gold after they have been rinsed of acids! Basically, put "clean" strips directly into the basket of the ultrasonic cleaner.
I'll try to make some videos with narration instead of, or in addition to, text so the viewer can be relieved of having to watch and read at the same time.
I enjoyed the narrated part especially. The bandwidth may be better than text overlays exclusively and allow for more dense information conveyance in future videos.
Grind the foil of with a dremil and then float the debris in water. Gold will sink the the bottom. Use a tissue layed on the water surface to pick the debris up and slowly poor the water though a filter to catch your fortune.
I used to work in a facility that made electronics for the telecommunications industry. This was back in the mid 1970s. All of our circuit boards were gold plated. We used a wave soldering machine. After a certain number of boards the solder had to be changed out because it was alloyed with gold! The solder price was about $5.00/pound. It was worth more than $50.00/pound as scrap. We had to change it because the connections were not soldered properly.
Sometimes the experiments that don't work and as interesting as the ones that do. Unless you try these hypotheses you will never know. Another interesting video. Thanks.
usually plain heat near 250 degrees will un-bond the gold plated copper from the PC board. I would simply bake the Boards for an hour. then the copper should be able to be pulled off.
250 C or 250 F? I've tried various chemicals on samples I have like acetone, alcohol, toluene, benzene, trichloroethane, and heptane, the problem is that the circuit board substrate is fiberglass and I don't know how the Gold is glued onto it. I have many kilos of edges like in the video, fingers, contacts, etc. and for the edge connectors I was thinking of just dremeling off the Gold foils and melting that down using the glass as flux (AFTER panning as much glass off as possible, of course).
james pogrebetsky Who cares if it isn't pure. It was a great video by a competent 'chemist' that was a joy to watch. He can take his $35 of gold and give it to his mother as a nice little gift.
I don't think you can get optimized cavitation by being target material in an container and placing that in the Ultrasonic cleaner. Put the target material directly in the Ultrasonic cleaner to see if the cavitation can really remove it or not
Dang I was under the impression after the original weigh in of 500 grams I know it has all the plastic still but to yield just 2 grams,?? I was shocked but thanx for making it look so easy every other video I've watched here on CZcams evefy1 else makes it look so difficult ya know like so many different processes but you Sir have the very best recipe I've seen for this process thank ya so much I been saving foiks for a while I just hope I yield a little more than 2 grams lol but it's all up to the batch I am hoping I get at least 10 grams . Well thanx bud much appreciated
You are absolutely correct, The time and money spent for such a small amount of gold does not make this worth while doing. Cheaper to buy gold than tryng to process or refine it from computer parts
The ultrasonic cleaner served _no_ purpose in this experiment, except for heating (if you had the heat on, that is). The cavitation bubbles created by the US will collapse when they meet a solid medium, in this case the glass. Try the same thing again without the glass, just with the 'fingers' in the cleaner. Use max heat and a normal cleaning solution, i.e., not the acid. Place the fingers in a stainless steel net (or something) that keeps them from touching the bottom of the cleaner's tank. The cavitation bubbles can only form in a liquid medium, and thus surfaces that are in contact with the tank walls will not be affected (cleaned/stripped). Note that I do NOT know whether this will strip the gold plating, or whether US can do it in the first place, but if it works, this is the way to do it. Furthermore, I reckon your cleaner has less than 50W of US power, which might not be enough.
it is $40 per gram today... Not good for one day of work (unless you do it as a hobby and give to your grandchildren to sell everything and lose all the money with stupid investments, anyway we take nothing when we die, other than spending a fun time on this present time) ... lol
That was very impressive. I'm glad it wasn't easy an you didn't get a lot of gold because at 1st I'm like, i need to start finding old computers. Lol I'm way to lazy for all that work. Good job.
You do realize that the sodium bicarbonate that you added to the ultrasonic is to protect metal that is directly exposed inside of it. Doesnt do anything if it is in a separate container placed inside of the ultrasonic.
but the bottom of the foils contained base metals like copper no? A simple rinse was enough to get rid of them? I mean the result not looked so shiny, for me it not looked like pure gold, am I mistaking?
Recovery and Refining are two seperate and different processes. You are not mistaken, the bead was not bright and shiny. It had a dull matt finish. And the purity is unknown. To get it to high purity it MUST be refined. In this video I did the recovery process and skipped the refining process and went straight to the melt.
Yeah well the brock was about 50% Gold but that's still very good because he only started with about 500g of material. That's nothing compared to what I have and that's why I'm researching input from people who've actually done this. Refining that down to 0.999 is not that hard using reverse electrolysis. I've done parts of all these procedures as experiments to see what I should do including the electrolysis, which goes pretty fast.
very good and professional,I did wonder why you wasted the time to dissolve the gold in the first bids,sure it was pure but prob just by a hundredth percent
I only did it for the benefit of those who were wanting to get the pure gold. Otherwise I would have just melting the foils and thrown the impure gold button in with my next batch of karat scrap for refining.
Buy PVC drain pipe and end caps from the big box store. Glue cap on one end, add fingers, HCL, (leave some open space glue other end cap on. Put into the bed of your pick up truck after a few days of driving and the tube rolling around in the bed of your truck,,,,,,,
In the first video, at the end of the experiment... he stated that after refining the gold that was extracted, the final yield was 1 gram of 999 fine gold... So I wonder how much of a difference in quality the unrefined gold was? I know that it doubled the weight... But I am wondering if whether you lose a margin of your gold during the refining steps????....OR..... Could it be that skipping the refining stage leaves so many other unwanted metals inside is your gold, that it is ½ as pure, and therefore not 990, 995, or 999 fine.... But possibly not even considered pure enough to be considered gold yet.. .but rather some kind of alloy? If it is still considered gold, or even fine gold... Then I would have to question 2 things... That my stannous chloride had possibly been tampered with, or my method of refining was subpar altogether, and quite obviously wasting alot of computer fingers.... Which is a sin... I guess?
The gold foils are about 12k gold or 50% pure gold alloyed with other metals for durability. I didn’t refine these foils, went straight to the melt dish. So that button was about 12k gold - estimated
I believe the extraction process is being extended because of the room (or lack there of) you are giving the card fingers inside the beakers ,give room for the card fingers to move and interact with each other while the process is taking place.Find a way to stimulate agitation during the entire process.IE the stirring needs to take place constantly. It may help your results.
I didn't refine the foils in this video. Instead I just melted them into a button. That button was only about 50% pure gold or 12k gold. So the two gram button only contained one gram of pure gold.
This is scrap dude. The ram and other boards these come from are literally trash and broken down. Here in Thailand a few people sell just the gold fingers for like $3 a kilo.
totalmente cierto, si sr, con éste método del ultrasonido fue mucho más corto, mucho más rápido y efectivo además de con un mayor grado de decantación y aprovechamiento que con el primero método que utilizó.
I believe the glass jar is creating a barrier to effectively remove the gold. The idea of an ultrasonic cleaner is it creates soundwaves and micro vibrations in the liquid to in affect peel the dirt/ coatings off. Because of the glass jar all your doing is preventing these micro vibrations from touching the items slowing the process. To properly do this the items need to be inside the bath space with fluid. But seeing as youre messing with chems its highly dangerous eapecially if the bath corrodes
Darrin b wrong on this one... Companies that produce these wave form removal systems. Have conducted 1,000's & 1,000's of detailed glass penetrating experiments. Proving the propagation of sonic waves actually does penetrate. With a 99.68% continues flow thru the medium. Sonic is well above vibration, and yet is vibration.
Would be nice to mak a video about how to neutralice all the acids, because some moron who gets access to this solutions may try it, and if he doesnt die of breathing the fumes, he may be so stupid to throw it to the drain......like most industrial companies do in India or Africa or South America...:-P
You can actually re-use the acids most of the time. Other than that, what's easier than neutralising an acid. Just add sodium hydroxide to it until it's neutral. You can use Ph test strips for this.
Of the 'fumes' of HCl in the video, no one died of the breathing therein, hence the upload of this video. By standing over an open drum of 26% Aqua Ammonia one will learn what not to do. If one does not have such commonsense, there is a strong possibility that one should not be performing arts in such ignorance.
MAY I MAKE A NOTE, IF YOU ARE DOING THIS INSIDE MAKE SURE THE FUMESA ARE GOING DIRECTLY INTO A GROW FAN-TYPE CENTRIFUGAL FAN WITH A HOSING LEADING OUTSIDE. TO GET A BETTER IDEA , WATCH GLASS BLOWERS. as grunthos said unless u cant smell, taste , or see.. either of thoese seness should tell you that some forced air circulation is necessary. just do it how glass blowers do, grow fan above the rxn / torch / whatever is spewing out that cna be caught with a strong air catcher connected to a tubing leading outside or (in my case if ur pro) planned so that a n opening through the house is somewhat next to your system, and direct the rest away from you and the container that is your house
@@SunRabbit Could he neutralizing the acid with Sodium Bicarbonate instead of sodium hydroxide? Because he already use it to protect the ultrasonic cleaner.
Hey if it's just about removing copper, you could do it with ferric chloride; the one that's used for PCBs in electronics. And moving the chloride with something would help. But if you want to activate that CLH + H2O2 mix, sunrays (or some UV lamp) are a must.
There is no way I could in my opinion waste my valuable time going thru a crazy process like this guy did!!! Not to mention handling acid and chemicals from 👹, and breathing the fumes, cancer city. I have been buying gold and silver for the last 25 years or so. My wife will be inheriting a S load of Gold and silver from her parents, they are 95 & 91 yo. Either way, interesting video. My wife thinks I waste my time in CZcams. I beg the difference!!! I learn a heck of a lot in the Tube!! Curious Minds want to KNOW. I’m a retired US Army Senior Warrant Officer and Blackhawk Pilot 26 years and 8 years flying EMS helicopters. I called it quits in 2016, way too dangerous! I am very fortunate that I never was shot out of the sky in combat, got hit and had big holes though. EMS flying was actually much more dangerous, single Pilot Captain, 2:00 am in the morning, overcast sky’s, night vision goggles and every obstacle out there just waiting to snag me. That really sucked!!! It was a great job though flying helicopters for over 36 years, best manual labor, my hat is off to those hard workers. Again thanks for taking the time to put this video together buddy, God Bless
Surely there must be some easier method for removing the gold foil - such as Electrolysis. I understand that each finger would need to be electrically connected by anode / cathode. But (if the anode and cathode are rotating in a vessel immersed in a solution with all of the gold-bearing fingers), they will eventually all make electrical contact over time. Less chemicals. Less work. I'm not a Chemist, but enjoyed watching this time-consuming extraction of less than 2g of impure gold. Reading the comments below, the costs of extraction (by this method) includes electricity / chemicals / gases for heating. Also, we must include the number of man-hours!!
if you grind everything down, circulate the pregnant solution, and then stop circulating, the elements will settle into contiguous slices of [blah blah blah and gold, copper, etc] thus removing the need to tediously jumper clip each finger. If you use a windmill do mill everything down, there goes the electrical cost involved. if the electrolysis is powered by solar and or wind, drop your costs even further. I've been reading up on electro-extraction for a few years now, and while there's a limit to my scientific knowledge, I've amassed a fair number of documents on the subject, and would love to pick your brain on the subject?
HNO3 acid would be more effective at dissolving gold than HCl; or maybe a mix of both; afterwards attract the gold to an electrode with some direct current 3 to 4 volts...
You missed the whole point; he doesn't want the gold to dissolve. He even tests with the stannous chloride to make sure non is in solution. The purpose of the hydrochloric acid and peroxide is to dissolve the copper beneath the gold that forms the bond to the plastic board. The gold then just falls off.
Waaaaaaaay Too much work and a process to get that small little piece of gold. I think its super cool that you made a video on how to do it but was way too much work for that small reward . Cool video tho
not using distilled water in the ultrasonic reduces the cavitation of the transducers also u need to have it off the bottom of the tank to get maximum effect
Ive seen a few of your finger recovery videos now, (and by others, but not up to your fine standards) and agitation during the foil removal seems to be the key element to speed the process, but the air and ultrasonic are too gentle, some form of tumbler or stirrer seems necessary, otherwise just shred them smaller before you start
I can see this is a vey interesting satisfying hobby ....but when you factor the time and labour and cost of materials ....youre not gonna get rich doing this ....but I appreciate you enjoy the hobby .

@streetips You've got multiple videos about circuit board gold recovery. Thanks for showing all the techniques. What's the best??? Doing this at home. Have processors, trimmings, etc. Looking to make money.. not spend it.
The only way I've found to make a profit is by shooting a video and posting it on youtube. Other then that, I don't see a way to make it with escrap. Unless you can get a whole bunch for free. I only did these videos to show how it's done. I normally don't process this type of scrap because the yields are so low and much waste is created.
sreetips I appreciate the reply. I hope you successfully monetized the videos and understand how to do all that right otherwise you'll never see a check. I have an account with a precious metals refinery company. i.e. scrap gold, silver etc. I asked them about bringing escrap. they have a division that buys but you need hundreds of lbs. Curious what would happen if I clipped the boards and just burned off the waste. I'd be left with a chunk of mixed metal. tempting to send it in mixed with some gold!
The best way I've seen is to use a hot soldering pen to scrap the foils off. I think incinerating the fiber board to recover the gold foils has been tried (not by me) unsuccessfully. The boards burn producing volumes of billowing acrid black smoke and in the end, due to the fragility of their design, the gold foils vanish in the chaos and no gold can be found amongst the ashes.
literally **puts it in an ultrasonic cleaner, It looked to be doing absolutely nothing, To see how it works put a skateboard bearing loaded with grease in the stainless steel cleaner with boiling water and a few drops of dish soap, And the grease pours out of the bearing it is being torn out by the sound, Then you will see how effective it is.
Just to let you know, I have learned more from watching you work with chemicals and their reactions with metals than I did in chemistry, which I failed. You make it fun.
That's not really saying much if you failed chem.
I took one chemistry class back in high school. I got a “D” probably would have been helpful in refining though.

The cavitation bubbles can only form in a liquid medium, and thus surfaces that are in contact with the tank walls will not be affected (cleaned/stripped).
Note that I do NOT know whether this will strip the gold plating, or whether US can do it in the first place, but if it works, this is the way to do it. Furthermore, I reckon your cleaner has less than 50W of US power, which might not be enough.
Exactly.
I agree.
ikr
1.9 g gold = 30$ .... , 1 day work and chemical materials = 50$ then you lost 20$
how about the other metal he left in the can? he'll get lie 100+ from that
fuckoff hej how do you figure 1 gram of .999 gold is 7 bucks?
it is $40 per gram today... Not good for one day of work (unless you do it as a hobby and give to your grandchildren to sell everything and lose all the money with stupid investments, anyway we take nothing when we die, other than spending a fun time on this present time) ... lol
1.9g is $80
Where can I get gold 7 usd per grame pure 24k for that low just tell me my friend, and we will be very fucking rich soon both of us.
That was very impressive.
I'm glad it wasn't easy an you didn't get a lot of gold because at 1st I'm like, i need to start finding old computers.
Lol I'm way to lazy for all that work.
Good job.
Gold with green bits looks nice
You do realize that the sodium bicarbonate that you added to the ultrasonic is to protect metal that is directly exposed inside of it. Doesnt do anything if it is in a separate container placed inside of the ultrasonic.
This is a faster and cheaper solution than the previous one not? Better
You are a patient man.
Very smart using the air as an oxidizer once the peroxide ran out
i can feel the toxic by watchin the video
but the bottom of the foils contained base metals like copper no? A simple rinse was enough to get rid of them? I mean the result not looked so shiny, for me it not looked like pure gold, am I mistaking?
Chaosman88 he was making a point by not refining the bead. that's why his yield was high, the sample still had base metals in it.
Recovery and Refining are two seperate and different processes.
You are not mistaken, the bead was not bright and shiny. It had a dull matt finish. And the purity is unknown. To get it to high purity it MUST be refined. In this video I did the recovery process and skipped the refining process and went straight to the melt.
I see, thanks for the clarification
Yeah well the brock was about 50% Gold but that's still very good because he only started with about 500g of material. That's nothing compared to what I have and that's why I'm researching input from people who've actually done this. Refining that down to 0.999 is not that hard using reverse electrolysis.
I've done parts of all these procedures as experiments to see what I should do including the electrolysis, which goes pretty fast.
I was hoping that you'd make that point in the video to make it clearer, but very good job.
very good and professional,I did wonder why you wasted the time to dissolve the gold in the first bids,sure it was pure but prob just by a hundredth percent
I only did it for the benefit of those who were wanting to get the pure gold. Otherwise I would have just melting the foils and thrown the impure gold button in with my next batch of karat scrap for refining.
Buy PVC drain pipe and end caps from the big box store. Glue cap on one end, add fingers, HCL, (leave some open space glue other end cap on. Put into the bed of your pick up truck after a few days of driving and the tube rolling around in the bed of your truck,,,,,,,
In the first video, at the end of the experiment... he stated that after refining the gold that was extracted, the final yield was 1 gram of 999 fine gold... So I wonder how much of a difference in quality the unrefined gold was? I know that it doubled the weight... But I am wondering if whether you lose a margin of your gold during the refining steps????....OR..... Could it be that skipping the refining stage leaves so many other unwanted metals inside is your gold, that it is ½ as pure, and therefore not 990, 995, or 999 fine.... But possibly not even considered pure enough to be considered gold yet.. .but rather some kind of alloy? If it is still considered gold, or even fine gold... Then I would have to question 2 things... That my stannous chloride had possibly been tampered with, or my method of refining was subpar altogether, and quite obviously wasting alot of computer fingers.... Which is a sin... I guess?
Gold plating is never made by 24K gold, because it's soft. It's always the alloy.
The gold foils are about 12k gold or 50% pure gold alloyed with other metals for durability. I didn’t refine these foils, went straight to the melt dish. So that button was about 12k gold - estimated
@@sreetips May I ask you to make a video of acid tests for gold purity directly on various gold-plated fingers/connectors?
Thank you for your time 👍👍.
Should you have tried to put the parts DIRECTLY into the ultra-sonic basin? I think the beaker was preventing it from working
I think you are right. But the acid would have ruined my friends brand new ultrasonic cleaner.
Never thought of that but I think you're 100% correct!
My grandpa use to do this all the time. You even say the word gold and he would start to drool.
I believe the extraction process is being extended because of the room (or lack there of) you are giving the card fingers inside the beakers ,give room for the card fingers to move and interact with each other while the process is taking place.Find a way to stimulate agitation during the entire process.IE the stirring needs to take place constantly. It may help your results.
Thanks
.. me
Might be a good Upcycle for an old dough-making machine..slow constant agitation.
Bubbles!
80 $ gold
40 $ products
3 day working
Wow
I didn't refine the foils in this video. Instead I just melted them into a button. That button was only about 50% pure gold or 12k gold. So the two gram button only contained one gram of pure gold.
it's like 1000 $ materials for 50 $ gold
about 35$ it is not fine gold only 50% -.-
And what chems he has can extract at least twice as much value in gold as the investment.
Not to mention paying for the electricity to run it for days
This is scrap dude. The ram and other boards these come from are literally trash and broken down. Here in Thailand a few people sell just the gold fingers for like $3 a kilo.
It's just fun to do this type of stuff and experiment. He's not doing it as a get rich quick scheme.
Bahut acchi Jankari thank u Sar ji dhanyvad ji🎉
totalmente cierto, si sr, con éste método del ultrasonido fue mucho más corto, mucho más rápido y efectivo además de con un mayor grado de decantación y aprovechamiento que con el primero método que utilizó.
Maybe you should have put the stuff directly in the ultrasonic cleaner
I dunno, jus a thought, but maybe the beaker, kept the ultrasound from hitting the foils?
I agree
Nice flushing from beaker to beaker
I believe the glass jar is creating a barrier to effectively remove the gold. The idea of an ultrasonic cleaner is it creates soundwaves and micro vibrations in the liquid to in affect peel the dirt/ coatings off. Because of the glass jar all your doing is preventing these micro vibrations from touching the items slowing the process. To properly do this the items need to be inside the bath space with fluid. But seeing as youre messing with chems its highly dangerous eapecially if the bath corrodes
Darrin b wrong on this one...
Companies that produce these wave form removal systems. Have conducted 1,000's & 1,000's of detailed glass penetrating experiments. Proving the propagation of sonic waves actually does penetrate. With a 99.68% continues flow thru the medium. Sonic is well above vibration, and yet is vibration.
Spending thousands dollars to buy an ultrasonic cleaner, an entire laboratory and all the periodic table's elements to earn 1.8 g of gold: DONE
That's funny because I paid $20 for a $12,000 machine someone donated to a donation center. They can be found very cheap.
Would be nice to mak a video about how to neutralice all the acids, because some moron who gets access to this solutions may try it, and if he doesnt die of breathing the fumes, he may be so stupid to throw it to the drain......like most industrial companies do in India or Africa or South America...:-P
Good suggestion.
You can actually re-use the acids most of the time. Other than that, what's easier than neutralising an acid. Just add sodium hydroxide to it until it's neutral. You can use Ph test strips for this.
Of the 'fumes' of HCl in the video, no one died of the breathing therein, hence the upload of this video. By standing over an open drum of 26% Aqua Ammonia one will learn what not to do. If one does not have such commonsense, there is a strong possibility that one should not be performing arts in such ignorance.
MAY I MAKE A NOTE, IF YOU ARE DOING THIS INSIDE MAKE SURE THE FUMESA ARE GOING DIRECTLY INTO A GROW FAN-TYPE CENTRIFUGAL FAN WITH A HOSING LEADING OUTSIDE. TO GET A BETTER IDEA , WATCH GLASS BLOWERS. as grunthos said unless u cant smell, taste , or see.. either of thoese seness should tell you that some forced air circulation is necessary. just do it how glass blowers do, grow fan above the rxn / torch / whatever is spewing out that cna be caught with a strong air catcher connected to a tubing leading outside or (in my case if ur pro) planned so that a n opening through the house is somewhat next to your system, and direct the rest away from you and the container that is your house
@@SunRabbit Could he neutralizing the acid with Sodium Bicarbonate instead of sodium hydroxide? Because he already use it to protect the ultrasonic cleaner.
thank you. Very educational. Definitely will not even try doing that.
Hay
I would definitely say this is a hobby. Like building models.
For this particular video, definitely yes.
OMG! All that for this!!!
Why not?
No manches todo como un año u nomas no acababas
Hey if it's just about removing copper, you could do it with ferric chloride; the one that's used for PCBs in electronics. And moving the chloride with something would help. But if you want to activate that CLH + H2O2 mix, sunrays (or some UV lamp) are a must.
No, it's not
Very enjoyable and informative video.
That's a pretty big facility.
All those chemicals. ,I hope and pray you don't wash anything down the drain ,protect our water supply.
the rinsing part seems so random.
Interesting video, thanks :)
There is no way I could in my opinion waste my valuable time going thru a crazy process like this guy did!!! Not to mention handling acid and chemicals from 👹, and breathing the fumes, cancer city. I have been buying gold and silver for the last 25 years or so. My wife will be inheriting a S load of Gold and silver from her parents, they are 95 & 91 yo. Either way, interesting video. My wife thinks I waste my time in CZcams. I beg the difference!!! I learn a heck of a lot in the Tube!! Curious Minds want to KNOW. I’m a retired US Army Senior Warrant Officer and Blackhawk Pilot 26 years and 8 years flying EMS helicopters. I called it quits in 2016, way too dangerous! I am very fortunate that I never was shot out of the sky in combat, got hit and had big holes though. EMS flying was actually much more dangerous, single Pilot Captain, 2:00 am in the morning, overcast sky’s, night vision goggles and every obstacle out there just waiting to snag me. That really sucked!!!
It was a great job though flying helicopters for over 36 years, best manual labor, my hat is off to those hard workers. Again thanks for taking the time to put this video together buddy, God Bless
Mich, I've got about 2000 hours in fixed wing aircraft. The largest was a Twin Otter. That night flight with NV goggles sounds intense.
Damn bro that probably took an hour and you extracted $41 of gold...... so not worth the time and effort.
$41 an hour here in Argentina wouldn't be bad... Even if half remains after expenses and taxes.
60 dollars of chemicals and gas to extract 5 dollars of gold
1.9 grams of gold is worth $91.43 USD at the time of this post.
Roger Malone like that crap on a cheap circuit board is pure gold 😂😂😂
i always enjoy,rob
Surely there must be some easier method for removing the gold foil - such as Electrolysis. I understand that each finger would need to be electrically connected by anode / cathode. But (if the anode and cathode are rotating in a vessel immersed in a solution with all of the gold-bearing fingers), they will eventually all make electrical contact over time. Less chemicals. Less work. I'm not a Chemist, but enjoyed watching this time-consuming extraction of less than 2g of impure gold. Reading the comments below, the costs of extraction (by this method) includes electricity / chemicals / gases for heating. Also, we must include the number of man-hours!!
if you grind everything down, circulate the pregnant solution, and then stop circulating, the elements will settle into contiguous slices of [blah blah blah and gold, copper, etc] thus removing the need to tediously jumper clip each finger. If you use a windmill do mill everything down, there goes the electrical cost involved. if the electrolysis is powered by solar and or wind, drop your costs even further. I've been reading up on electro-extraction for a few years now, and while there's a limit to my scientific knowledge, I've amassed a fair number of documents on the subject, and would love to pick your brain on the subject?
Fascinating! As far as the thumbs down you should read his intro. Doing so might save you from looking like a idiot.
well im poor as hell and I was just looking for ways to get real gold to make egyption healing rods...too much work / expensive equipment for me
Buddy empty pockets don’t keep people down I’m sure you’re rich in mind you can come up with ideas to help you make something out of nothing
I was zoning out watching you, then you started talking and scared the shit out of me haha. good video by the way
HNO3 acid would be more effective at dissolving gold than HCl; or maybe a mix of both; afterwards attract the gold to an electrode with some direct current 3 to 4 volts...
You missed the whole point; he doesn't want the gold to dissolve. He even tests with the stannous chloride to make sure non is in solution. The purpose of the hydrochloric acid and peroxide is to dissolve the copper beneath the gold that forms the bond to the plastic board. The gold then just falls off.
Paint shaker,if that wont do it nothing will
mike jones's right. Nothing like putting acid into a paint shaker. What happens when it builds up gas inside?
Then put a check valve in it
Or don’t put acid in a paint shaker.
of course it didn't work, all your doing is cleaning the outside of the beaker in the ultrasonic cleaner, lol
I think the use of bubbles delivered by hose in the beaker would increase the amount of foil removed
Wow alot of work for such a small yield
I COULD DO BETTER STANDING ON THE CORNER WITH A SIGN HUNGRY NEED BEER MONEY
I agree, but at least now you know the truth about what this type of scrap will yield in gold.
Waaaaaaaay Too much work and a process to get that small little piece of gold. I think its super cool that you made a video on how to do it but was way too much work for that small reward . Cool video tho
finally i Find a Vid That Dont Refine Kool Vid Great To Know
nice work. safe. scientific. entertainment that makes money.
Thank you.
La cuestión no es perder dinero como dice el tío listo de abajo sino el verte capaz de hacerlo y ver el proceso.
Whole video quiet then we get to 7:30 where a waterfall comes from nowhere hah
Oh my gold!
not using distilled water in the ultrasonic reduces the cavitation of the transducers also u need to have it off the bottom of the tank to get maximum effect
Ive seen a few of your finger recovery videos now, (and by others, but not up to your fine standards) and agitation during the foil removal seems to be the key element to speed the process, but the air and ultrasonic are too gentle, some form of tumbler or stirrer seems necessary, otherwise just shred them smaller before you start
I can see this is a vey interesting satisfying hobby ....but when you factor the time and labour and cost of materials ....youre not gonna get rich doing this ....but I appreciate you enjoy the hobby .

Very complicated process, has simpler forms, and that work very well, does not need this whole freshness.
@streetips You've got multiple videos about circuit board gold recovery. Thanks for showing all the techniques. What's the best??? Doing this at home. Have processors, trimmings, etc. Looking to make money.. not spend it.
The only way I've found to make a profit is by shooting a video and posting it on youtube. Other then that, I don't see a way to make it with escrap. Unless you can get a whole bunch for free. I only did these videos to show how it's done. I normally don't process this type of scrap because the yields are so low and much waste is created.
sreetips I appreciate the reply. I hope you successfully monetized the videos and understand how to do all that right otherwise you'll never see a check. I have an account with a precious metals refinery company. i.e. scrap gold, silver etc. I asked them about bringing escrap. they have a division that buys but you need hundreds of lbs. Curious what would happen if I clipped the boards and just burned off the waste. I'd be left with a chunk of mixed metal. tempting to send it in mixed with some gold!
Why not? If it contains gold then their XRF will detect the amount in your chunk. My video shows a way, not the way, to get the gold from the fingers.
sreetips thanks again for the reply. What would be the safest procedure for me to seperate the metals from the board cuttings. acetylene torch?
The best way I've seen is to use a hot soldering pen to scrap the foils off. I think incinerating the fiber board to recover the gold foils has been tried (not by me) unsuccessfully. The boards burn producing volumes of billowing acrid black smoke and in the end, due to the fragility of their design, the gold foils vanish in the chaos and no gold can be found amongst the ashes.
literally **puts it in an ultrasonic cleaner,
It looked to be doing absolutely nothing,
To see how it works put a skateboard bearing loaded with grease in the stainless steel cleaner with boiling water and a few drops of dish soap,
And the grease pours out of the bearing it is being torn out by the sound,
Then you will see how effective it is.
Good to see you posting again :)
Reminds me of what's floating around in Goldschlager.
