Palladium from ceramic capacitors (MLCCs) - recovery and refining
Вставка
- Опубліковано 25 вер 2024
- Pyrometallurgical extraction of palladium from ceramic capacitors (MLCCs). Pd is recovered by smelting of the capacitors with lead and silver followed by cupellation. The resulting Pd-Ag alloy is then dissolved in nitric acid. Further palladium is refined and precipitated using formic acid.
this clip was really nice because you showed it in very clear detail, thank you very much for your honesty in training.👏👏👏👍👍👍 When I see the sincerity of people like you, I am happy. Thank you very much
My pleasure!
Espectacular el video gracias por compatir tu conocimiento ,me a ayudado a comprender la recuperacion de plata y paladio 👍
In the end this method is interesting because for those like me this turns primarily on the DMG or (dimethylglyoxime). The product used here so t easier to find, thanks for the demo and beautiful result
Thank you!
Thank you Master. I am a beginner. Your video is very educating
Thanks for watching
Наконец то понятная инструкция по извлечению палладия.Большая просьба,сделайте титры на русском.🙏
будет
@@OwlTech333 интересно посмотреть осаждение палладия с грязного раствора,а то бывает провтык в напайках попадается палладий, серебра много, меди тоже,и палладия чуть,выливать жалко,плюс ювелирская 375 проба имеет палладий,как тогда?
How much lead and how much silver did you add to the peak amount you weighed while melting the capacitors?
What I want to know is how many grams of silver and how many grams of lead you melted the capacitors. thank you .
hello please guide me.
Pd-Pt-Au has been dissolved in Aqua Regia.
Au aut .. with SMB.
What should I do for my Pd crash?
It collapses with ammonium chloride. But I cannot rinse off the precipitate!
What else do you suggest, thanks.
I'm not familiar with the ammonium chloride procedure
Hola muy buenos los videos, enhorabuena. Con los catalizadores es igual?
Hello very fine the videos, congratulations, whit the catalizadores is the seim?
Sory mi English
Gracias
Thanks for sharing. This has really helped me out.
Glad it helped!
pardon me brother but the first of your treadetional clip you wasn't clear how amount of (MLCC s)weight?and in the end did you accunt beaker weight with the palladium ?the number of 58.63
the weight of the beaker is 58.63 and the weight of the the beaker with the dried Pd powder inside is 60.56 from there you can get the weight of the Pd: 60.56 - 58.63 = 1.93g Pd
I can see how things have changed from when you ferst started whish I had been fallowing you from the start !
:) Never too late
You always make it look so easy. You're a master.
Thank you! I am flattered!
@@OwlTech333 are you a chemist or metallurgist
@@johnbackes2266 neither, only a hobby of mine :)

what is Dore and what is formic acid and where can I learn of all of these components and solutions is there like an encyclopedia
en.m.wikipedia.org/wiki/Dor%C3%A9_bar

19:40 Can the formic acid be substituted by anything else?
Ascorbic acid (Vitamin C)
Сова молодец и лайк как всегда! Но блин завязывай с пирометаллургией,представь сколько паров и чего при купеляции ты вдыхаешь не смотря на вытяжки и защиту!
Impresionante, Cuáles son los reactivos? los materiales para llevar a cabo esto exactamente...? Quisiera hacerlo en una práctica de laboratorio...
Gracias...
Y que clase de condensadores cerámico son...? Cualquiera o alguna nomenclatura específica...?
Do all old capacitors have palladium I have lbs of them from the 70s brown like that blue green black clear I mean I have a lot
not all capacitors, just some of the MLCC type
How do you separate palladium capacitors from tantalum, both looking alike
Tantalum have polarity - + marked
It is very easy to separate tantalum capacitors becoz you can see a +ve pole marking on one side of the all tantalum capacitors
What solution you dropped at 10:23 is it water ?
Distilled water
@@OwlTech333 thanks bro 🙂
Thanks for sharing your job !
Using PH reduction is the easyest method when you work with clean solution.
The cleanest you disolve, the easyest you recover...
If we deal with precious metals, we should now get a ride to Tantalum recovery...
Would you take part of this challenge ?
Love and Peace.

Excellent job, what is the benefit of sodium hydroxide for scarification ?
Great job, well done sir
Thank you! Cheers!
hello.
Firstly, I wish you healthy days
Will the clear solution after pd powder precipitate pd from the next pdcl?
so can we use it again because formic acid and sodium carbonate are at the desired level ..
Привет, классно купелирование показал! спасибо за русские субтитры.
I got lots of Capacitors with palladium in them, how do I know for sure?
Test them
@@OwlTech333 Sorry to ask but Is it possible to test without Chemicals?
@@stevebad100 There's no simple answer to your question. If they are of certain type and with certain markings one can tell the composition and quantity by simple search on google , for the rest... XRF, cupellation or chemical test are the options.
Hallo owl tech, please, help me:how can I get out copper from the goldsolution, acqua regia, the color is black. Give me please an info... Thanks Pit/Germany
if you have removed the gold before that, you can cement the copper on iron
Wait a minute now what kind of MLCCs are those exactly, they don't (from that first initial glance we were shown when you began to start incinerating them) I'm in the states. These appeared to be those other types of ceramic capacitors with two legs on them standing upright when mounted on a PCB. I'm accustomed seeing exceedingly tiny components that has the brown/light brown/dark brown/gray/white/and occasionally silver color tops with distinctive soldered ends at 2 sides, in the shape of being primarily rectangular, although square also exist.
These are Eastern-Block produced high-performance MLCCs of the 1960s-1980s. The USSR had plenty of palladium available, so they used it to increase capacitor performance. As far as I know, Western capacitors didn't use palladium (at least as much as the soviets did).
@@bormisha cheers my friend ! Thank you very much, quite interesting information ! Much appreciated !
Thanks for gold work creative man they are mazy work
My pleasure

Are these caps particularly high in Pd? They look old and large.
Yes
The richest in palladium are Soviet KM capacitors and variable resistors. You never dreamed of such a content
Привет! Супер процесс! А исходных КМ было 1,13 кг? На весах очень плохо видно. Большой лайк!

What’s the heating plate is stainless steel grade sir
yes, stainless steel
What was the purpose of smelting it with lead in the beginning?
tyler beyer to collect the palladium and to remove the base metals
@@OwlTech333 is it necessary if you just melt it all and use dilute nitric to disolve base metals?
@@tylerbeyer4316 My knowledge, here, is purely theoretical, as I haven't yet done any of this stuff. I'm just paraphrasing things I've read at the goldrefiningforum, and I admit I may have a few details inaccurate, but:
You can incinerate the mlccs without smelting into lead. But, then you should dissolve the base metals in HCL before moving on to nitric. The problem with this method is you then have to deal with ceramic dust clouding everything up and getting in the way of filtering.
Smelting in lead eliminates that mess.
Hello. What was yield in these batch (g Pd/kg MLCC)?
The Pd was recovered from 173g capacitors
11g / kg
60.58 (total weight) minus 58.63 (beaker weight). That gives you 1.95 g of pure palladium powder from this batch of mlcc's. Very nice yield and another great video! Cheers🙂👍🍻
Once again watching your demo glueed on computer screen.
When Dore was dissolved in nitric acid, there was a sludge left. What's that?
If you can't or don't want to answer, that's no problem. The video itself was quite instructive. Thanks again.
No sludge grains of the Portland cement

@@maxcloutier5285 lowers the melting, plus It's easier to collect 50g ag alloyed with 2g Pd than trying to find the 2g Pd alone
So if i already have Cl2Pd (in dust/granulate form), can i dissolve it with chloridic acid and then precipitate the Pd with oxalic acid?
don't know about oxalic but you can do it with formic acid
@@OwlTech333 i hope it can work with oxalic, as i know the Pd precipitates when the Ph of the solution is around 5 or above

Can the potassium hydroxide be substituted by anything else?

can i use oxalic acid in place of formic acid for palladium recovery?
no

Video y traducción
На всём протяжении просмотра данного ролика не проходил один вопрос: ЗАЧЕМ?? Для чего вообще был использован этот дикий, варварский средневековый метод - купелирование?? Чтобы потерять часть металла в глёте? Надышаться ядовитыми парами соединений свинца? Почему просто было не протравить обожженый материал сначала азотной кислотой (забрав Pd & Ag) , а потом - в ЦВ , чтобы забрать Pt. Что мешало сделать проще и безопаснее? К чему эти изъёбства ?
BaTiO3
Hello, how to use this process with catalysts?
yes
Sir, how much capasitor you have used, for obtained 60 gram of palladium?
suhar yanto That was about 2 grams of palladium. The beaker he used had a tare weight of 58 grams written on the side.
Thanks
Thanks for your video I get new idea
Most welcome 😊
Зачем вы добавили гидроксид натрия?
How many grams of palladium is extracted from one kilogram of thickeners?
what thickeners?
60g palladium from 173g capacitors???
gaz21lit yes minus the weight of the beaker 😄
Bro are you joking 1/3 gram of capasitors become 1 Gr Palladium . Everyone must ve fool on world working father then looking wasteboxes from old electronic circuits
Very very good information 👍
Please give me your phone number
The best video I've watched about pd.
Pb what happened?
Is nitric acid concentrate or 1/1 water initially?
How and at what step did we get rid of lead (Pb) dissolved with nitric acid?
YAKUP YAZICI the lead is removed in the beginning after smelting during the cupellation process
@@OwlTech333 So the bullet was left in the pot.
When it starts without fencing, it becomes a damn solution that is attached to the filter and does not drain.
"We are solving this problem with" NaOH + Pb + mlcc + melting ". Did I get it right?

Congratulations for the video, but if the pH reaches 7 or exceeds it begins to precipitate, along with the reduced metallic palladium, all the hydroxides of the base metals that the solution has as a contaminant.
Not all but many, that's why pH 6 is somewhat critical - the Pd is precipitated with only a fraction of the silver
