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.

dude, your channel should have more subs cause the work you do is absolutely stunning!

Great vid buddy! Didn't get exactly what was anticipated, but that's science for ya! Throws us a curve-ball now and again. Thanx again! :D

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.

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.

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.

James, if I had to do it again I'd incinerate to a fine ash then hit the ash with aqua regia instead of using acid peroxide.

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 😁👍❤️🙏

Came along way in production quality since this. No wonder you don’t do the SIM cards anymore. Your on to bigger and better things these days😂😂

I love your videos you remind me of my geology and chemistry professor faud nobari and Mr Stan..

Another fine video. You are a great inspiration. I was eager to see a good yield and was able to share in your disappointment..

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!

Wow this was hell of the work. Thank you.

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 ;)

Great job with the camera work, real good video

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.

Thanks for sharing your methods.

wouldnt a vibration table or ultrasonic work better at keeping it agitated ?

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!

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

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

Doesn't too much smb make other metals precipitate out? If more is added when theres no presence of gold?

You're awesome buddy! Breaking Good.. lol

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.

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

@sreetips

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 So after the first filter of foils, is the gold contaminated with other metals also or did the acid dissolve those metals?

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).
