Smelting 1.7kg ceramic capacitors (MLCCs) using lead and silver as collector metals, followed by cupellation, silver - palladium separation and palladium melting.
My eternal question is, & I've asked it many times, in many places, how do you identify resin dipped capacitors that contain palladium? I can identify resin dipped tantalum capacitors, but no one answers how you identify the RD capacitors that contain palladium.
@@mareecathie2476 no specific way other than knowing your capacitors by look alone. I usually take a sample of say 10 pieces, weigh them, incinerate, crush, and process to get yield, then add a picture with yield data to my cheat sheet at home. That way I can go after specific grades and save time in the long run.
@@redbaronrefining5322 Thank you so much for your answer, RB. Sort of sticks a hole in my grand plan :-) I scrap a lot of circuit boards & just sell the chips as I'm not set up to refine. I was hoping I could do the same with them. Thank you, again.
@@OwlTech333 Economic or not, that was an hour long video, cut and condensed. Those torches were blowin the whole time. All I was saying was that the gas was flowin the entire video.
What happens with the lead oxide vapor? I would imagine that it will affect health very negative after some time of exposure. How can u make sure to not be slowly poisoned by the lead fumes. Thank you. I would appreciate an answer! Kind regards🖐️
I would suggest making a vent hood with a high cfm volume for drawing away the fumes into some sort of exterior filter box outside the building you’re doing this in. PPE, such as painters respirator, rubber smock, full face shield and nitrile gloves are a must in any caustic process.
Do you recover your own capacitors or buy them ? If your buy them I have probably 4 kilos of capacitors right now and probably have about 10 in the next month and the bored I have with the most capacitors sell at low grade so
I know this reply was from a while back but have you watch mount baker monument metals? You may want to check out how he incinerates with a cone mold the cupels to extracts the base. He may be interested in the 5lb of capacitor you have.
Wouldnt it be more easier to pour the calcined ground ash into aqua reqia then wash it few times and boil off the water or add some chemicals to precipitate palladium ?
Hello, if I burn the PCB boards withhout separation all the parts on it, is possible use the cupellation process? and if yes can I get all the precious metals like Au, Ag, Pt, Pd, Ta, and others? thank you for your answer
39:11 the base does not scratch piles jewelry trick when it is at room temperature we will add isopropyl alcohol this will detach the metal from the glass creating a mass to which we will add a powder We will add a similar bolomen of liquid borax, this amalgam will prevent metal from being lost during the fusion and I recommend using a granite crucible with Tesla fusion or induction fusion.
Sağol kardeşim çok çok çok teşeķürlér ediyorum size birşey sormak istiyorum bu palladyumu pilastikleri erintikten sonra ateşte bunun tozunu ayırdan sonra nittrik asitdeni direk potada eritsek olmazmı sağol canım kardeşim kolay gelsin sana teşekürler
To remove the final led from the palladium, you should add some sulfuric acid after you denox the solution and look for precipitation of lead sulfate. Add more sulfuric acid until there is no more precipitate. That should solve the lead problem for you. The pink crystals in the filter looked like lead chloride to me, the color was probably from something else included in the white needle formed crystals.
Hi Göran! I don't think there's any lead left in the button or at least there shouldn't be since I took three 3 steps to eliminate it before precipitating the palladium: 1st step was the cupellation itself, 2nd step was chlorination (any lead should have precipitated with the silver as the corresponding chlorides from the chilled solution) and the 3rd step was the de-NOxing with sulphamic acid which converts the free nitric acid to sulphuric in situ thus precipitating any lead that made it this far as lead sulphate. With the above said I'm more inclined to think that the XRF gun needs calibration... not sure As for the pink crystals I think it's Vauquelin's Salt ([Pd(NH3)4PdCl4] Lou and freechemist mentioned it on GRF goldrefiningforum.com/phpBB3/viewtopic.php?t=9023#p86042) but again not sure...
@@OwlTech333 Your final XRF reading shows 5.8% Pb. It's a bit much just to come from a badly calibrated XRF. As you say, a chilled chloride solution should precipitate most of the lead and the rest could easily be taken care of by the conversion of sulfamic acid turning into sulfuric acid. But lead chloride takes a while to precipitate, that's why it can form quite long and thin crystals. I suspect that you got so much lead nitrate that the denoxing of nitric acid didn't produce enough sulfuric acid to remove all the lead in that step. But that's just a theory of mine. Putting a few drops of sulfuric into a solution is a cheap and instant way to verify if you have lead in solution or not. And for the few times you got lead it alerts you for a problem that might cost you a lot later on. But if you don't think you have any lead in your final button then you can just disregard all that I wrote. :-) I've never seen Vauquelin's salt as crystals, only read about it in articles and on GRF. I don't know if it forms thin crystals just as lead chloride does. If you still have that filter paper a quick XRF should tell you if it is lead or palladium. Thanks for sharing that video. I have half a kilo of MLCC:s to process in the summer. But I'll probably go the wet chemistry way after incineration. It's worked well for me before.
Nice video , i have some problems can anybody help me ? After cupellation while i was dissolving the metal in nitric acid all metals were dissolved except gold.. after that i was purifying gold with second boiling in nitric acid but gold was started to dissolve in nitric acid it was like water soluble gold nanoparticles now I am stuck how can i precipate gold ...?
I got like close to 3 kilo of these resin dipped ceramic capacitors mostly blue and brown ones with a few mixed odd colors. This votes well to a very good yield when I get the materials to process them. One is always hoping anyway been collecting and saving a long time now. I also have over 2 kilo of ic chips saved up that should be good also.
How to eliminate excess nitric acid any one please help me? I added urea to neutralise the solution and after adding SMB but I didn't get any gold dust
To eliminate excessive nitric acid, do I heat the aqua regia before or after adding the suphamic acid? Or do I add suphamic acid at outside temparture? And how do I know when to stop adding suphamic acid? Thanks if you reply.
@@franchi8601 I do it after dissolution, I keep adding sulphamic acid until solution stops fizzing then I dilute with water or ice leave it to cool and then filter
Very cool process. Is it possible to get higher purity or at least remove the lead? I know you can't remove the platinum, but would a second refining be worth the effort?
11:17 in the pan where you stir the nitric acid solution you must place a base 1 cm of silicon oxide and pay it with aluminous and activator the rest to cover you will use the same type of silicate that is used for pavement painting is cover the reflective silicate is nitro pearls if silicon and pure silicate this will affirm the heat and distribute it amogenous throughout the pilex base

I love watching your videos. I would appreciate it if you make a video on tin mine recovery from electronic cards. I wish you many successful days in your life, greetings from Turkey.
Wow like all your videos this one is great as well. Can anyone send me pictures of what ones I should be saving & what kind of metals they have. I am just getting started & have about 400 lbs right now of 4K video boards & stuff I was going for the gold but would love to get everything
Hi John. Great video Please stay safe and healthy and take care of yourself and your family members. To all members also. Talk to you later my friend. ☺☺☺😇😇😇
Отличное видео. А Вы пробовали данный метод для переработки автомобильных катализаторов? Или может знаете как лучше переработать ? Интересует как извлечь родий. Будет интересно увидеть видео.
думаю этот метод будет в Топе для переработки пыли от чёрных микросхем и т.п. вот там вообще будет извлечение супер. да и для катализаторов с родием наверно единственный способ где будет полное извлечение. это чисто мои мысли на основе видео и общения с знающими или практикующими людьми. прогресс у автора на лицо- выходы приближаются к исходным. я печь уже сделал,тигли купил. пыль есть, вот с горелками пока проблема.- потеплеет будем пробовать.
Dear @UC6bp-Swp9caHmPm22KiujEg, thank you for your effort, I really appreciate it. I have samples of river silt, and chemical analyzes have proven that it contains gold at a rate of 1% per 100 grams. But I could not extract gold from samples, neither by chemical methods nor by gravity sedimentation, perhaps because gold is microscopic gold? Can you help me with your experience and give me some advice on this issue?
My question is, how can you tell which ones are silver, gold,platinum or palladium? I have a big jug of a variety of sizes out of old tv’s , flatscreen tv’s and computers and old stereos.
@@OwlTech333 so what you’re saying is that it doesn’t matter what color MLLC or capacitor it’s all the same? How can that be when there’s different metals in each type? I’m confused.
