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.
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 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.
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 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 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!
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 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.
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 😁👍❤️🙏
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 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!!!
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 !!!!
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
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 ;)
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).
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
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!
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 ....
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.
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.
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.
You Produced $90.99 worth of Gold. (Price per gram $50.55 * 1.7g). Total EBay Cost $126 A week of work and chemicals. I admire what you did, but won't be doing it myself.
That's the reason I created the video. So people have a place to look BEFORE they go out and spend their hard-earned money on this kind of over-priced scrap.
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.
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.”
Boil the sim card to separate the metal core from the shell, waste the shell and process the metal core with aqua regia. It's a lot less chemical and time needed.
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.
accetone would melt the plastic right off and shouldnt damage the gold or the underlying circuitry. aggetate it. scoop plastic off of the top then drain and dry it then blend it. most of ur issues are solved with just that alone
Youngin, that is way too much trouble for 1.7 grams. You spent more than that on the cards, not to mention the chemicals. You did recover the gold. I just grind that stuff in a rock grinder down to 120 mesh, then put it in a tumbler, half full or so, 3/4 full of water, add 1 teaspoon of lye and 3 tablespoons of charged mercury and tumble for 4 hours. Then chamos off the mercury, put the sponge in a test tube, pour a bit of distilled water and a pipet of nitric. That eats the quicksilver and leaves the gold. I can easily get my mercury back, and there is my gold!! It ain't fancy, but it's been working for 6000 years ;)
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.
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.
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.
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.
I would hav stuck with the concentrated hydrogen peroxide in 100ml incremental doses every 24 hours. You would have had a much higher stripped amount to start with. Your result of 9 days and I could clearly see several cards untouched when you rinsed them is far too long with little result. this should have only taken 72hrs +\- 24hrs with only 400-500ml of the hair salon h2o2 (dosed at 100ml per 18-24hrs ) if you do this again try what I suggested and I guarantee you do it this way every time. After continuing on watch if you would ha dissolved the “S and B” in warm water stirring until it won’t take anymore Sodium and Bi.... let it settle then use the concentrated solution to precipitate the gold to avoid contamination of excess powder.
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.
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?
@@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?
@@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?
Charcoal lighter fluid is a VERY low grade combustible. Everyone I know has done the exact same thing when grilling. Only dangerous if you are extremely careless.
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
@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
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
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?
So i had done this a while back. I used Peroxide, vinegar, table salt, and put the scrap precise in to a Mason Jar with the ingredients. I actually got a pastel teal green and baby blue liquid with gold flakes floating around there was a bit of an odor So I placed it outside on the balcony. We live upstairs I placed it on the opposite side of people. Well lo and behold, long story short. There's no longer liquid in the Mason jar that I forgot outside it has become a foam like consistency with everything in cased into a pellet the size of the Mason jar. There is visible gold flakes and foiling from all the Excel phone parts and chips different boards and memory cards SD cards and pins. Now with all that said, my question is how do I get the gold out now of my baby blue teal green chalk pellet?
The paste dissolves with muriatic (hydrochloric) acid. Once dissolved and you can see the gold foils filter them out and dissolve with muriatic acid and bleach.
26:30 mark you mentioned AQUA REGIA. I use aqua regia to wash the gold plating from the ceramic surfces of a cathode ray tube. The gold wasnt plated over nickke or copper but applied directly to the cermanic rear deflector the aqua regia instancely washed the gold ..so i would say wash tge gold plating off with aquia regia In attempts to do as you have done to gather gold from a foil , i had five lbs of copper foil plated with gold that i stripped of of antique telephone back planes . And i used diluted nitric acid to put the copper in solution the gold plating floated on the top . It looked like a gold mine . But on gathering the gold by skimming you would not believe how little gold i got . It wouldnt even cover the bottom of a sewing thimble. . 5 lbs of circuit board gold plated runners from well before 1972. . I mean it took 2 months if razor blading the runners off for a dollars worth of gold. At that time about 1999 gold spot price was like $300 troy oz
Robert, for these reasons I don't process much escrap any more. It looks like a lot in the funnel or the beaker. But after refining, the yields are just too low.
@@sreetips yes. The refiner in Philadelphia relied on eye glass frames and jewelry as his main income source. But he would accept single scavengers and collectors of electronic scrap. He didnt make purified bars but rendered it down to sale to larger refiners. To get to many electronic componets it takes herculean effort to even get to the gold plated stuff. To get any voljmn requires n arrangement wih industrial electrical installers . In my area 50 miles outside of Washington DC . One should be prepaed to purchase rolloff containers of scrap electrical dismantaling stuff . Military auctions. Or even hole in the wall military subcontractors that develop prototype electronics stuff . That siurce is where i got that solid silver wire from a dumpster dive. With the owners premission. That multi stranded silver wire is easy as anything to strip . Time consumming of course.. The work that has to be done to gather , purchase clean and refine electronic scrap . It would make more sense to work at 7/11 and save up to buy gold ir silver
wouldn't it be quicker & more cost effective to just burn up sim card casings under controlled temp. under melt point of gold, shift out foils from ashes and then process ???
My thoughts also, but great representation Sreetips! We used to burn huge piles of wire for copper extraction prior to chem bathing, cut our time consumed by like 70%.
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.
really excellent business, less company and individuals can't do. now, per grams of gold was up high and more continued to it.. economy is continue crashing,, golds going up more with all metals, iron, copper, aluminium, silver to gold
I think you might need some more agitation in the bucket then the little air pump, possibly a few more or perhaps use a plastic ice cream maker to stir and agitate your solution.
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.
What happened with the water used to rinse the sim cards? normally there were some flakes in it? I also had a doubt about incineration because some gold was maybe gone with the smoke. Thanks for your videos.

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.”
This guy got more patience than 20 Saints
Boil the sim card to separate the metal core from the shell, waste the shell and process the metal core with aqua regia. It's a lot less chemical and time needed.
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.
I’ve never had that happen
A lot of contamination
accetone would melt the plastic right off and shouldnt damage the gold or the underlying circuitry. aggetate it. scoop plastic off of the top then drain and dry it then blend it. most of ur issues are solved with just that alone
next project... condense your videos down from eternity...
Youngin, that is way too much trouble for 1.7 grams. You spent more than that on the cards, not to mention the chemicals. You did recover the gold. I just grind that stuff in a rock grinder down to 120 mesh, then put it in a tumbler, half full or so, 3/4 full of water, add 1 teaspoon of lye and 3 tablespoons of charged mercury and tumble for 4 hours. Then chamos off the mercury, put the sponge in a test tube, pour a bit of distilled water and a pipet of nitric. That eats the quicksilver and leaves the gold. I can easily get my mercury back, and there is my gold!! It ain't fancy, but it's been working for 6000 years ;)
Nice!
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.
I should have burned the SIM cards. Then hit the ash hard with aqua regia
sreetips really has nailed down branding.
i am Excited for the next video i hope it will be the catalyst recovery..good work
I just finished part one of the cats video, it should be posted by tomorrow..... finally!
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.
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?
My question as well... I was surprised to not see you deNox with Sulfamic acid ?? But very clear process, per your usual great videos.
Gary, I don't have any urea because I never use it. I did have sulfamic but I just kept adding SMB until all the excess nitric was gone
Karl, I had it, but I just kept adding SMB until all the nitric was gone and the gold came down completely (with the crystalized 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.
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.
Buon giorno. Buonissimo. Mi guardo sempre,solo che non capisco americano. Abito in Italia ma sono Russo. Ciao.Laik
Tu,non mi capisci?
Se scrivi in italiano non ti capisce :)
wouldnt a vibration table or ultrasonic work better at keeping it agitated ?
Great job with the camera work, real good video
Burning plastic is so toxic! I hope your neighbors aren’t close enough to suffer from the fumes. Take care of yourself when you do that!
It’s very slight, almost nothing compared to the exhaust of your neighbors car.
Perodically Dosing the hcl with the stronger peroxide would of made it more efficient at removing the gold and quicker.
thanks again for making your videos.
I would hav stuck with the concentrated hydrogen peroxide in 100ml incremental doses every 24 hours. You would have had a much higher stripped amount to start with. Your result of 9 days and I could clearly see several cards untouched when you rinsed them is far too long with little result. this should have only taken 72hrs +\- 24hrs with only 400-500ml of the hair salon h2o2 (dosed at 100ml per 18-24hrs ) if you do this again try what I suggested and I guarantee you do it this way every time. After continuing on watch if you would ha dissolved the “S and B” in warm water stirring until it won’t take anymore Sodium and Bi.... let it settle then use the concentrated solution to precipitate the gold to avoid contamination of excess powder.
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.
Wohh! Almost! Great job.
If you melt the SIM cards in acetone first would make your life easier
Very good...
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?
I thought those batteries were silver oxide. Silver oxide should melt directly into silver after removing it from the case
Experimentation is the name of the game sometimes. Great job Sreetips.
I'd like to try these again. Incinerate to a fine ash then aqua regia.
@@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 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.
1.7 g for all that effort and liquids etc mustve not been a profit
not the point. gold recovery is a gamble. plus, if he saved that solution, i'd bet he could de nox it & drop a cpl more g's...
April 2020 Value: $91.36
Damn, that little bead is worth more than my 5 bags of recycled bottles and cans!
You just NEVER add combustibles to a open flame, NEVAAAAAAAAAAAAAAAAAAAH
Charcoal lighter fluid is a VERY low grade combustible. Everyone I know has done the exact same thing when grilling. Only dangerous if you are extremely careless.
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
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
For anyone wondering, profit is $90.56 for 1.7g of gold as of October 22, 2022.
Can’t verify that
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
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.
So i had done this a while back. I used Peroxide, vinegar, table salt, and put the scrap precise in to a Mason Jar with the ingredients.
I actually got a pastel teal green and baby blue liquid with gold flakes floating around there was a bit of an odor So I placed it outside on the balcony. We live upstairs I placed it on the opposite side of people. Well lo and behold, long story short. There's no longer liquid in the Mason jar that I forgot outside it has become a foam like consistency with everything in cased into a pellet the size of the Mason jar. There is visible gold flakes and foiling from all the Excel phone parts and chips different boards and memory cards SD cards and pins.
Now with all that said, my question is how do I get the gold out now of my baby blue teal green chalk pellet?
The paste dissolves with muriatic (hydrochloric) acid. Once dissolved and you can see the gold foils filter them out and dissolve with muriatic acid and bleach.
26:30 mark you mentioned AQUA REGIA. I use aqua regia to wash the gold plating from the ceramic surfces of a cathode ray tube. The gold wasnt plated over nickke or copper but applied directly to the cermanic rear deflector the aqua regia instancely washed the gold ..so i would say wash tge gold plating off with aquia regia
In attempts to do as you have done to gather gold from a foil , i had five lbs of copper foil plated with gold that i stripped of of antique telephone back planes . And i used diluted nitric acid to put the copper in solution the gold plating floated on the top . It looked like a gold mine . But on gathering the gold by skimming you would not believe how little gold i got . It wouldnt even cover the bottom of a sewing thimble. . 5 lbs of circuit board gold plated runners from well before 1972.
. I mean it took 2 months if razor blading the runners off for a dollars worth of gold. At that time about 1999 gold spot price was like $300 troy oz
Robert, for these reasons I don't process much escrap any more. It looks like a lot in the funnel or the beaker. But after refining, the yields are just too low.
@@sreetips yes. The refiner in Philadelphia relied on eye glass frames and jewelry as his main income source. But he would accept single scavengers and collectors of electronic scrap. He didnt make purified bars but rendered it down to sale to larger refiners.
To get to many electronic componets it takes herculean effort to even get to the gold plated stuff. To get any voljmn requires n arrangement wih industrial electrical installers . In my area 50 miles outside of Washington DC . One should be prepaed to purchase rolloff containers of scrap electrical dismantaling stuff . Military auctions. Or even hole in the wall military subcontractors that develop prototype electronics stuff . That siurce is where i got that solid silver wire from a dumpster dive. With the owners premission. That multi stranded silver wire is easy as anything to strip . Time consumming of course..
The work that has to be done to gather , purchase clean and refine electronic scrap . It would make more sense to work at 7/11 and save up to buy gold ir silver
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...
wouldn't it be quicker & more cost effective to just burn up sim card casings under controlled temp. under melt point of gold, shift out foils from ashes and then process ???
Yes, I concluded that after I seen all the gold foils left in the SIM cards.
Would this also work with CPU and RAM? That would make everything easier.
My thoughts also, but great representation Sreetips! We used to burn huge piles of wire for copper extraction prior to chem bathing, cut our time consumed by like 70%.
"I've got my bubbler over here" Oh nice mate, smoke up :P
This shit is breaking Bad legal
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.
For the best yield these should be incinerated to a fine ash. Then extract the gold with aqua regia.
really excellent business, less company and individuals can't do. now, per grams of gold was up high and more continued to it.. economy is continue crashing,, golds going up more with all metals, iron, copper, aluminium, silver to gold
Ya, sim cards are a bust. Great vid as always.
I think you might need some more agitation in the bucket then the little air pump, possibly a few more or perhaps use a plastic ice cream maker to stir and agitate your solution.
Nate. If I did this experiment again I'd incinerate everything to a fine ash then hit it with hot aqua regia.
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.
What happened with the water used to rinse the sim cards? normally there were some flakes in it?
I also had a doubt about incineration because some gold was maybe gone with the smoke.
Thanks for your videos.
