Nice, 7 g per kg, wow, that is a lot... I was way off guessing 4 g, probably because cell phone BGAs are small... Ancient method it is, first book about it TREATISE ON ORES AND ASSAYING is from 1573 written by Lazarus Ercker, mint master in Kutna Hora, near my hometown. Was main textbook about fire assay for 300 years... First book using scientific method in technology. Ofcourse, method is older than that, some sources say 4 500 years old...
1.73g It was more than I expected (1,56 g) . This metalurgical method I've seen it in others youtubers like owltech , mbmmllc, etc I appreciate your efort to make this video . Keep going
The yellow fire released after adding naoh meqns that the reaction produce hydrogen gas... can you explane to le how naoh makes yiu get rid of carbone please?
dissolved gold in aqua regia and during the presipitation there was a lot of non-neutralized nitric acid so I put a piece of copper in the solution and dissolved it a week later I obtained sediments which I boiled in HCL then rinse and boil again in 65% nitric cine and I obtained a cloud of black material floating according to your experience what is black cloud
The best miner for gold ❤
Like muito bom esse processo 👏🏾👏🏾👏🏾👏🏾

Thanks for watching mate. Of course these tiny toys should be old enough to yield this way.
Wow such stunning info....like to read the first book...👍
This chips are from very old cellphone they contain more then the newer ones

That wasn't too far from it though...👍
Thanks my friend🙏
Nice picky! Stay safe over there!
THANKS buddy 😊
Love it!
So delighted to hear this, mate!
I like this cast iron pot
Ma shaa Allah!!
Yep another nice vid .The stanus shows palladium ?? 😮
Thank you my friend 🙏
Yes . Imagine how much palladium is being wasted in the nitric acid leaching method.
Sweet video.... Thanks. Did OwlTech guest produce this video? (LoL, He's a great channel to learn from)
Thanks for watching my friend 🙏
other than the toxic fumes from burning of the chips and cupelling, i like this video...
A fume hood supported by a bag filter system with a cyclone would solve the problem.
thanks for watching mate.
Good job.
Can I use copper instead of lead?
For cupellation no you can't. But You can use copper as the collector metal then dissolve it in nitric acid to get gold powder
How do you get those off the phones?
IC chips mounted on the PCBs just heat it and separate
Que paso con el paladio de la solución? Lo llego a recuperar ?
Lo agrego a la solución de desecho, olla sopera. entonces lo recupero asi

C + 2 NaOH + H2O = Na2CO3 + 2 H2
And produced sodium carbonate used as the flux itself
@@PickyPlansthank you very much
nice a video bro .and good result 🌹🌹🌹🌹👍🔥

It could be gold or platinum according to the first material you dissolved.
@@PickyPlans thank's i relly love all your vidéos
I'm grateful for your kind words 🙏
Witam i pozdrawiam serdecznie z Polski 🇵🇱👍👍👍
Thanks mate 🙏
Excelente
What purity do you get with this method?
I get +990 usually 995
@@PickyPlans That is amazing.
👏👏👏👏
tthe pot looks good ,what material is it?😂
cast iron ladle used for carrying molten aluminum
i thuoght was 310 stainless steel ...
Can I precipitate the gold in aqua regia with aluminum?
With too much nitric acid, passivation won't let gold percipitate out.
Also if that happens you will get a mix of all metals.
Harika çalışma ustam. Ustam alt yazı seçeneklerinde TÜRKÇE olsa daha iyi olur teşekkürler usta.
Teşekkürler arkadaşım 🙏
Ne yazık ki altyazılar videoda ses olmadan çalışmıyor. Sesli videolar yapmaya çalışacağım
فيديو رائع
شكرا جزيلا🙏
تسلم اخي العزيز
