I have to give you props for hanging in there and getting what you could get out of it. I admit I would've given up the first time the gold precipitated back into solution. Good job.
That was a amateur mistake you cannot precipitate out of solution without denoxing any leftover active acids first. Urea should have been added slowly till it stoped reacting. Only then can you add percipetant to drop your metals out of solution.
Awesome video, i love the content and learn heaps. I have used ammonium perchloride for removing gold foils. Now i nedd the nitric acid to purify them.
I can appreciate all the time you put in this video..chemistry like all science is trial n error over n over.as for myself ..the whole process just sends my committee into OVERLOAD.
You actually explained everything thoroughly. Other videos used text, or robot voices. This was a very entertaining, and educational experience, watching this, and I would like to say thank you. I was rooting for you, the whole 47:39 mins. Did not skip any of it. Again thanks alot.
I bet you get more yield on copper and tin on your waste bucket, than on gold out of these simcards. You'd need a shitload more and a more efficient process to make a profit. But hey, it's a learning process, very informational and great fun to watch! Keep doing this!
Thanks for the Video! Excellent Quality like always. As you showed in 2016 already, SIM Cards are not worth the effort, even if you get them for free. But ist a Gold refiners challenge :-) Your actual yield is lower than expected in respect to your 2016 Video. I calculated a 2g yield from the roughly 1200g of SIM Cards. I think incineration from the beginning would have been the optimal approach. But we wouldn't know for sure without this Video of yours. Thanks again.
The pot transistors that are raised above the circuit board base . They look like steel buckets about a quarter inch square . They typically have gold plating bottom plates . Gold plated on both sides. You have to pry off the steel buckets to reveal the gold plating or detach from the circuit board and look on the bottom side where the naked wires come out
Not on this video , but related . I searched you channel and found a couple videos dealing with you stock pot - getting more out of them . Also looked with waste , but didn't find if there was one , on dealing with options of eliminating chemical waste . I have not seen much , but many seem to ignore lesser metals , at least copper and maybe lead & tin , should be a lot percentage wise . Still trying get enough volume doing electronics repair , scrapping has become a side line . With gold silver etc. being a hobby ;)
I wonder if using something like a wiper motor from a car, you could create a agitator that would keep the product moving and perhaps friction might help to remove the foils more quickly
I'm curious how you might approach this differently now with the lessons learned from this batch? Would more initial mass make the time & material investment more worthwhile (4lbs? 5lbs?) Also, if you started with incineration, would you follow that with the aqua regia right away or still wash with nitric acid to dissolve the substrate metals first, then AR etc? I'm fascinated by the chemistry and I really enjoy watching your work. Thank you!
I have watched most of your videos. Very informative! You know your craft well. I have some metallurgical background but not in this style. I am genuinely curious if anything is actually profitable from buying bulk and refining from a small perspective. I do have a question, have you tried to refine the computer part "gold" bars from eBay? Would it be something to look into? Most look like brass to me.
Drop melt bars various computer parts melted together. I’ve got a video on it. They are a total ripoff. You pay $29 for $2 worth of brass and get just a trace of gold - almost nothing.,My experience. Please see my video titled “how to make a profit refining precious metals.”
I love watching your stuff but cant get over the loss you absorb in your experiments! Spent close to $225 on the chips for about $70 in gold, thats rough!
Xtreme Performance very true! I avoid buying any sort of scrap from ebay. Even the gold filled stuff that one used to get good prices on has skyrocketed in the last few years. People paying well over spot for the stuff.
Great video ! Getting better every time. Idea: write 'sreetips' backwards inside the corningware. It'll reflect the right way round off the big beakers ;) Who said denox ? wasn't me ....
If you could figure a way to put a big massive magnetic stir bar in there to keep those sim cards heavily stirring that would likely speed the stripping process up significantly.
Awesome video thanks, could you please estimate how much materials cost you expended. I would love to know how much it cost you to produce the 1.7 gram of gold.
In your case, I think Patreon wouldn't be charity. I think lots of your viewers would like to chip in a couple of bucks for these excellent lessons. I would, but I can't afford to buy gold and I don't want any jewelry. If you feel strongly about not taking any charity, you could do give-aways of gold buttons or whatever when the experiments have been thoroughly paid for. I supported a miner and he sent me a little rough gem as a thank you and it was so much fun.
Thanks Sreetips. It was a tricky one but a good lesson all the same. Any thoughts on getting a small kiln in the future so you might do as our metallurgical forefathers did, and reduce such things into a button and then use a bone ash cupel and Pb to remove the base metals? I wonder if there would be losses that way also. The obvious gains would be the ability to complete the entire process in a matter of hours, as opposed to many days.
@@sreetips Have you considered putting them into a blender whole to make a granular plastic / gold mixture and then burning them with the torch to fine ash then refining with aqua regia?
Great job with the video. Putting the filter on the camera. You are a handful of only a few who go above and beyond for your viewers 👍👍. I've tried BGTs and ICs but have found the manufacturers are VERY skimpy on their precious metals. I'm in the process of extracting silver and palladium or platinum (I hope) from old radio crystals. I'm dealing with a LOT of quartz debris that is being a bit stubborn. We'll see how "skimpy" the manufacturers were back in the mid 90s😁. Keep recording, we'll keep commenting 😁👍❤️🙏
Good video as usual. I wonder if you got all the gold from the acid peroxide step. I have a bunch of sim cards but i'm not going to rush to process them for the gold. I'd get more money on ebay (thats where I got them) but it feels like I'm scaming someone if I do that.
If I did this again I would skip the acid peroxide and just burn the SIM cards to ash. Then grind the ash up with a mortar and pestle, then hit the fine powder with aqua regia. I might order some more and redo the experiment using that process.
I enjoy your knowledge sir. I take my sim cards and place them in a pan of ALL purpose sand and place the pan on a burner so I can control my heat. Put small amount of sim cards on top of the sand. Mix with sand it takes about 10 mins and it will steam the plastic off my cards. U have to watch because they will stick together. Not the gold but the plastic
I’m amazed that your yield was so low from the SIM cards. I wonder if it’s due to the foils on the SIM cards being so thin. Also, any idea why the acid bath was not successful to get the foils to release? Thanks for this great video!
Awesome video, I have been recovering silver from unused large Ag+/AgCl batteries. These are hard Ag+/AgCl and Magnesium plates that are easily separated. The best method of conversion is a work in progress. Any suggestions?
Great video, I was not surprised on the yield, it takes a lot of sim cards to produce a small yield. I have played around with them a little my self. One question though, was there a reason you did not denox the excess nitric with urea in lieu of saturating with SMB?
I just checked ebay prices for sulfamic vs SMB and just looking at the first listing, SMB $20/lb. with Sulfamic Acid @ $6/lb. And then not those SMB crystal ppt. to deal with. Again, your videos are outstanding, this one showed your problem solving abilities and experience.
Hi streetips I was wondering if you could do a video of gold refining from satellite LMB’s as the board is pretty much covered in the stuff. I love watching all your videos and I will continue to do so thank you so much and I hope you have a great day/night.
Electronic scrap is very popular. That's why I made the escrap videos. But honestly, the yields are just too low and the amount of waste high. For these reasons I don't do much escrap refining.
LMB boards are not gold plated. They are gold flashed. 1 or 2 gold atoms thick. You will never get foils off of LMB boards, it will break up so small all you will see is microscopic glitter. i have a freind who gave me 10 lbs of them. I ran them just to show him how little there was. About .7 grams if I remember correctly, that was several years ago
You should try dissolving simcards in acetone or paint thinner. Paint Thinner is better because it dissolves slower than acetone, and after about 30 minutes you can take out chips and plastics, and reuse the thinner, While 30 minutes in acetone and it is quite polluted with liquid plastics (but maybe its cheaper way, I must test it more).
To get them to strip completely, it takes a couple of days in A/P. I don't process anywhere near that amount, but I use a 1 litre beaker with A/P at about 70-80c, with a bubbler, for about 3 days. All are as clean as a whistle.
At 39:04 you said "boy this is going to be fun" , and i thought i was going to fall out of my chair from laughing so hard !!! Up until then i was thinking this poor man has spent hours working on this and i already would have given up if it was me , but in the name of science you stayed in the trenches , good man !!!!
Just watching this and have a question. Would pulverizing these cards or any PC scrap I guess, in a ball mill be more efficient than burning? Thanks for sharing your work.
I saw this thing on Cody's Lab where he had an issue with rinsing out the gold solution with Muriatic acid and then precipitating it with SMB because the acidity was too high , so he added some hot water and the gold dropped right out with the addition of hit water.
@sreetips So after the first filter of foils, is the gold contaminated with other metals also or did the acid dissolve those metals? How much gold do you loose after you liquefied and then precipitate back into solid? Does the acid (any acid) eat away any amount of gold that cannot be recovered? Is this the best method for unpopulated NEW circit boards? I have so many i need to either sell or continue this process. Thanks for your videos. This is a great way to keep people from hurting themselves due to lack of knowledge. Again thanks for sharing knowledge.
Not quite sure of their composition, but the foils are not pure gold. It would be best to incinerate all these cards to an ash and then recover the gold from that ash with hot aqua regia. But there is so little gold here that is hardly worth the effort.
@@sreetips I have blank green boards unpopulated, with nicely plated gold contacts to solder. These are new boards, some are 3in x 3in, some 6in x 4in. Approximately 50 of the small boards and roughly 20 of the larger. Can i send pics to see if you would be interested in another project, maybe another video?
I have been fascinated by your channel and videos here of late. Your quality has really come up especially since you started appearing and narrating. I get the impression you aren't a chemist by trade? What is your day job? Anyway, thank you for the videos, chemistry is cool.
I have no formal chemistry training. Everything has been trial and error with some help from the folks on the goldrefiningforum.com I work at a jewelry repair shop setting diamonds for customers. Chemistry is fascinating. Thank you.
I don't think SMB will precipitate copper. But if copper is in solution with the gold then some of the copper solution may get trapped in the precipitated gold and contaminate it. Thorough rinsing will rid the gold of the copper. It's always best to do a second refining if you have a bunch of copper in your gold refining waste solution.
@@sreetips then what on earth is the point? This literally cost you way more than the $80 or so dollars of gold you get out of it. Why do you do this its a total waste of time money and effort?
That's why I stopped doing the escrap as much, not much yield and unless you get the stuff for free it's hard to turn a profit. Glad to see it done for educational purposes though.
@Elektra Delphi the phidelphia refiner would incinerat whole backplane and circuit boards then dump the ash and metals in a ball mill. And from there I don't know what he did. Sounds very messy when it comes time to separate the metals . I'm thinking there is more value in the solder than the precious metals
The 40% peroxide is probably way less than 40% because it degrades into water at room temperature. We keep high strength peroxide in the refrigerator to prevent degradation. We also start with freshly manufactured product. If you consider that product from a beauty salon will probably sit in a warehouse somewhere unairconditioned for who knows how long, then it goes to the salon where its stored at room temperature for who knows how long. Its easy to see that the purity will be greatly affected.
@@sreetips it could be even less. You would have to titrate it with KMnO4 to know for sure. We get 50% and after a month in the refrigerator it's already about half strength.
Another beautiful production. Sorry if i'm are inconvenient in ask, but what about the gold that were left on the filter separated with the hydrochloric acid and the peroxide at the beginning of the video? And,would not it be nice to add some sulfuric acid to the solution containing iron? The ferrous sulphate formed could release some gold that was bound to iron. Just theoretically speaking.
when you have excess nitric like this, you could heat the solution to reduce it to maybe 5%-10% of the volume. that should greatly reduce the amount of nitric and speed up the process.
@@sreetips that's probably the best way for sure. There's so little gold it's not worth the trouble. Out of 1200g scrap you only got $100 of gold. It probably cost half that in chemicals.
Coolnventions computer scrap has a lot better content than regular ore, I saw another video of a facility that processes scrap by the ton. Pretty cool.
Go for it then , launch yourself in sim cards recycling lol , looks to me like you ll waste a lot of money on products for a less than appreciable result . He doesn t even get 2 grams of gold from more than a kilo of simcards. So basically can't even pay for the cads he bought with that gold , not to mention all the transformation :) Go and melt some copper you ll earn more coins from this .............
christophe Dohet were talking about the company that buys computer scrap by the ton and processes it at their facility, not these small mom and pop recoveries.
I think you lost much of your gold on the burn. That ash is very lightweight and can be carried away easily with tiny flecks of gold on the ash. But overall I think you did as best of a job as possible. My question is; Would it be possible to dissolve and separate via gravity (the plastic that dissolves floats on the top of the acetone and metal sinks) the plastic components away from the metallic components using something like acetone before using aqua regia to dissolve the metals?
I came across this video today and I was wondering why it didn't work out. I am thinking that if you had burn it first and then did the process, might have been a different outcome. Not sure if you tried this again, if you did can you supply the link so I can watch that version. Thanks for giving us a great video and some great information. Stay safe and see you on the next video
Oh btw. seen they guy from Mount Baker mining? He can grind up your slag and puts it on the shaker table to extract the heavy metals from it. Probably your amounts are more efficient to just grind up and pan out. The guy from mbmmllc he also grinds up the crucibles.
I'm thinking about doing the vinegar and salt mix to recover some gold and then probably put the filter paper from those recoveries in jar, till I'm ready to refine and melt! With green fiber do you think that would be a good first try at gold recovery?? Or do you have any other words of wisdom for me? Have a GREAT Day!!!
I can watch this stuff all day. My daughter showed me that I can watch you on my flatscreen tv it's only a 55" but it's going to be cool to watch your vids on it instead of my little phone. However it won't allow me to comment on it, at least I don't think it will. Have a GREAT Day My Friend!!!
Why are you not utilizing both ports from the air pump? I have that same pump and I know that it doesn't pump a crazy amount of are so you may as well be using both of them to your advantage
So you have to buy all the raw materials to extract the gold, then there's all your chemicals that cost money then all your working time so do you turn any profit at all? or is it pretty much a break even deal?

Not quite sure of their composition, but the foils are not pure gold. It would be best to incinerate all these cards to an ash and then recover the gold from that ash with hot aqua regia. But there is so little gold here that is hardly worth the effort.
@@sreetips
I have blank green boards unpopulated, with nicely plated gold contacts to solder. These are new boards, some are 3in x 3in, some 6in x 4in. Approximately 50 of the small boards and roughly 20 of the larger. Can i send pics to see if you would be interested in another project, maybe another video?
Sorry, I only refine my own material
Learn something new every time I watch
Great Video, thanks. Joe
sreetips really has nailed down branding.
How clean was your fume hood those days.
It's more experienced and dirty right now in your new uploads.
Because I just replaced the motor last week, it’s as clean as my wife’s kitchen floor.
@@sreetips 😁
can't wait to see that clean hood 👍
love the video but that must of been expensive
I have been fascinated by your channel and videos here of late. Your quality has really come up especially since you started appearing and narrating. I get the impression you aren't a chemist by trade? What is your day job? Anyway, thank you for the videos, chemistry is cool.
I have no formal chemistry training. Everything has been trial and error with some help from the folks on the goldrefiningforum.com I work at a jewelry repair shop setting diamonds for customers. Chemistry is fascinating. Thank you.
Wow! Very educational.
I was cracking up when you burned the sim cards. I bet that smelled soooo bad
That is a one of a kind smell. Once you smelled it.... I could smell it even when he was burning them. Lol
Vent hood. :)
You should use some kind of agitator along with the bubbler.
Nah, it's better to use a ball mill, and then run it through the blue bowl...
H! mr.sreetips.. A have a question. In your first attempt adding the SMB in 18:18 is that possible you will precipitate other metals too (ex:copper)?
I don't think SMB will precipitate copper. But if copper is in solution with the gold then some of the copper solution may get trapped in the precipitated gold and contaminate it. Thorough rinsing will rid the gold of the copper. It's always best to do a second refining if you have a bunch of copper in your gold refining waste solution.
Thankyou :)
it was very informative thanks
It was more than I thought. I think they use the least amount on these cards because they are disposable.
This guy got more patience than 20 Saints
If you have an excess of hno3 then we must do to remove all hno3 in it
Thank You Sir
great video. I would have been interested in a total / overall cost-benefit calculation to see whether this was all worth the effort or not.
No way, the yields are too low.
@@sreetips then what on earth is the point? This literally cost you way more than the $80 or so dollars of gold you get out of it. Why do you do this its a total waste of time money and effort?
@@T-bird_Johnny This video has 122,000 views and going. THAT is why he does it.
That's why I stopped doing the escrap as much, not much yield and unless you get the stuff for free it's hard to turn a profit. Glad to see it done for educational purposes though.
Is it possible to Pyrolytic incinerrate the sim-Cards and desolve the Ashes? Edit: nevermind, just 30 secs later you dit it.
@Elektra Delphi the phidelphia refiner would incinerat whole backplane and circuit boards then dump the ash and metals in a ball mill. And from there I don't know what he did. Sounds very messy when it comes time to separate the metals . I'm thinking there is more value in the solder than the precious metals
The 40% peroxide is probably way less than 40% because it degrades into water at room temperature. We keep high strength peroxide in the refrigerator to prevent degradation. We also start with freshly manufactured product. If you consider that product from a beauty salon will probably sit in a warehouse somewhere unairconditioned for who knows how long, then it goes to the salon where its stored at room temperature for who knows how long. Its easy to see that the purity will be greatly affected.
It’s actually only about 12% peroxide
@@sreetips it could be even less. You would have to titrate it with KMnO4 to know for sure. We get 50% and after a month in the refrigerator it's already about half strength.
Another beautiful production.
Sorry if i'm are inconvenient in ask, but what about the gold that were left on the filter separated with the hydrochloric acid and the peroxide at the beginning of the video?
And,would not it be nice to add some sulfuric acid to the solution containing iron? The ferrous sulphate formed could release some gold that was bound to iron. Just theoretically speaking.
The filter with the gold foils was in the big beaker. I poured the incinerated SIM cards right on top of it and then hit everything with aqua regia.
Truth! It was even mentioned.
I hoped it would be possible for a slightly more expressive gold result from those cards.
Thanks!
when you have excess nitric like this, you could heat the solution to reduce it to maybe 5%-10% of the volume. that should greatly reduce the amount of nitric and speed up the process.
Jim, if I even try this again I’ll burn the SIM cards first then do an extraction with aqua regia on the ashes.
@@sreetips that's probably the best way for sure. There's so little gold it's not worth the trouble. Out of 1200g scrap you only got $100 of gold. It probably cost half that in chemicals.
I’m loving the videos. Funny thing I just realized that I feel like Jesse Pinkman watching Walter White.
Hahaaaaaa!! Me too! Lol
thats 43 troy oz per tonne. most mines produce .5oz per ton
Coolnventions computer scrap has a lot better content than regular ore, I saw another video of a facility that processes scrap by the ton. Pretty cool.
Go for it then , launch yourself in sim cards recycling lol , looks to me like you ll waste a lot of money on products for a less than appreciable result . He doesn t even get 2 grams of gold from more than a kilo of simcards. So basically can't even pay for the cads he bought with that gold , not to mention all the transformation :) Go and melt some copper you ll earn more coins from this .............
christophe Dohet were talking about the company that buys computer scrap by the ton and processes it at their facility, not these small mom and pop recoveries.
There will be a day i watched everything you made. Oh wise one!
If you melt the SIM cards in acetone first would make your life easier
Doesn't too much smb make other metals precipitate out? If more is added when theres no presence of gold?
I think you lost much of your gold on the burn. That ash is very lightweight and can be carried away easily with tiny flecks of gold on the ash. But overall I think you did as best of a job as possible. My question is; Would it be possible to dissolve and separate via gravity (the plastic that dissolves floats on the top of the acetone and metal sinks) the plastic components away from the metallic components using something like acetone before using aqua regia to dissolve the metals?
I don't know. I don't have much experience with this kind of material. The yields are too low.
I came across this video today and I was wondering why it didn't work out. I am thinking that if you had burn it first and then did the process, might have been a different outcome. Not sure if you tried this again, if you did can you supply the link so I can watch that version. Thanks for giving us a great video and some great information. Stay safe and see you on the next video
What would have happened if you had added a few ml of Nitric acid to the batch?
April 2020 Value: $91.36
Damn, that little bead is worth more than my 5 bags of recycled bottles and cans!
I'm not 100% on this but if you separate the plated part from the plastic on sims it looks like there's a couple of bond wires in them
Very good...
Sreetips why dont you get a ball mill and pulverise these circuit type boards then do your extractions. More surface area means faster reactions.
Oh btw. seen they guy from Mount Baker mining? He can grind up your slag and puts it on the shaker table to extract the heavy metals from it. Probably your amounts are more efficient to just grind up and pan out. The guy from mbmmllc he also grinds up the crucibles.
I'm thinking about doing the vinegar and salt mix to recover some gold and then probably put the filter paper from those recoveries in jar, till I'm ready to refine and melt! With green fiber do you think that would be a good first try at gold recovery?? Or do you have any other words of wisdom for me?
Have a GREAT Day!!!
Shane, I’m not that familiar with salt and vinegar. I remember that the yield was low for that experiment.
I can watch this stuff all day. My daughter showed me that I can watch you on my flatscreen tv it's only a 55" but it's going to be cool to watch your vids on it instead of my little phone. However it won't allow me to comment on it, at least I don't think it will.
Have a GREAT Day My Friend!!!
Why are you not utilizing both ports from the air pump? I have that same pump and I know that it doesn't pump a crazy amount of are so you may as well be using both of them to your advantage
So you have to buy all the raw materials to extract the gold, then there's all your chemicals that cost money then all your working time so do you turn any profit at all? or is it pretty much a break even deal?
It's a loss. I don't refine escrap anymore because the yields are too low.
