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.

[@kenjett2434]

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.

[@Jason-vn5xj]

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!

[@sreetips]

I’d burn it first thing. No question

[@robertlewis5611]

You can use vinegar peroxide and Morton sea salt to extract the gold foils from the SIM cards works really good it just has to set longer

[@njanderson4342]

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.

[@golder70]

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'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 😁👍❤️🙏

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

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.

[@keithstreeter9054]

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!

[@sreetips]

I’m not sure. I’ve only done SIM cards this one time.

[@robertbrawley5048]

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

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.

[@OlderThanDirt-ii3rp]

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 ;)

[@sreetips]

Nice!

[@jowens1126]

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.

[@MrHanky_YT]

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.

[@GeorgiaDogScrapper]

[@johannesdesloper8434]

[@sreetips]

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.”

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]

I should have burned the SIM cards. Then hit the ash hard with aqua regia

[@DR_SOLO]

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?

[@sreetips]

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.

[@morningstar829]

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?

[@sreetips]

I don't know. I don't have much experience with this kind of material. The yields are too low.

My question as well... I was surprised to not see you deNox with Sulfamic acid ?? But very clear process, per your usual great videos.

[@sreetips]

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

[@sreetips]

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)

[@karlbe8414]

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.

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 .

I think you got all that Iron contaminate @ 37:06 - from the cast iron burn pan @ 23:51 - I would use high Q 440 SS pan !

How can I tell if I find one? That pan I used was laminated and it has begun to come apart - it was a saladmaster and I thought it would be indestructible - not!

I know I'm late on this, love your videos seen almost all of the 100 times! Basically all metal pans leach metals into what ever you are cooking, as far as I understand pyroceram would be better for incineration than metal, all stainless steel pans are 50% iron as far as my research has shown. Pyroceram can withstand temps of upto 1200 degrees and contains no metals to contaminate recovery efforts

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 don't understand why you would bother, when the yield was a fraction of the cost of sims.
