Full process Silver and Palladium recovery from MLCC (Part 2) Multilayer ceramic capacitors refining 

Thanks! Good luck, just slowly and patiently!

Can you find palladium?

Thanks!

Due to nitric acid neutralization.

Yes!😀

Silver was restored in the first part and palladium was restored in the second part.

You can also recover palladium using dimethylglyoxime.

It is necessary due to the change of pH, the mixing ratio can be seen in the video, I usually dose based on the color change.

Sodium carbonate performs this task,If smoke is generated, it will redissolve the resulting material.

it can also be recovered with dimethyl glyoxime or chlorine gas if dissolved in nitric acid, but I don't recommend either of these, DMG stinks, chlorine gas is tricky, safety comes first!

Everyone tries to use the solution that is available cheaply

@@qwethengoldrecovery thank you, i have all those substance in my small lab..just i don’t know why separation failed.. small amounts come out the rest stays in the solution

I was succeeded for the first time, around 1,3g palladium form mixed 40g mlcc.. just still didn’t know, the lights brown containing palladium or dark brown.. all those models are stick to the magnet ..

Did you completely remove the silver from the solution? I remember if silver remains in the solution, this part of the process also recovers the silver, so more "dust" is generated. One of my tips would be. It is possible that the solution has become too saturated, try diluting it with a little water.

@@qwethengoldrecovery Many thanks for your reply. I think the silver is gone. It was quite easy to separate (succesfully recovered - thanks) but I believe you are bit right. I took some of the powder and added nitric acid to it. The powder slowly dissolved in the acid turning it orange/brown (correct for Palladium if I understand it right). But...there where some black/brown pieces left on the bottom. I believe that is badly filtered ceramics. Also some white stuff...small pieces that fell apart after a while in the acid but not dissolved -laying like salt on the bottom together with the ceramics). What can that be ? So...filter the soup should do it. For the future...filter better before final boiling... What do you think ?

@@lars5065 Yes, there is probably dirt left in it.

@@qwethengoldrecovery A bit interesting...Over night the solution changed color to green (from orange/brown). This must mean that there were some nickle left in the "crap". Even the ceramic slowly dissolve. Still I believe we are on the right path. Just have to filter better/be more careful earlier in the process. Many thanks for your videos part 1 and 2. They make sence. Other videos, by others, handling the same process do not...

@@qwethengoldrecovery Hello again ! I re-tested som extracted materiel by pouring some nitric acid in it. It separates just beautiful. The fluid gets orange brown and I get some white lumps on the bottom (silver I guess). But...I also get a few black lumps which are quite annoying...what can that be ? Can I send You a picture/e-mail ?

I don't recommend it, the reaction is much more intense, it almost explodes. It's dangerous.

@@qwethengoldrecovery Thanks for the info!

Because it is a cheap, easily available, common language washing soda

Yes, I used formic acid in the video.

I use NaOH instead of NaCO. A bit less bubbling and no boil overs

@@qwethengoldrecovery nice work by the way :)

I don't know exactly, I buy it under the heading "laundry soda" available in stores.

How was copper precipitated? It can only be in the presence of iron.

@@qwethengoldrecovery I added a lot of sodium hydroxide and sodium carbonate, so the solution was completely equalized. I treated the sediments and separated the palladium from them.

not to the best of my knowledge, but there may be a procedure for doing so

Yess.and its the best to get out silver and palladium

It is difficult to estimate this, as in the video, I add partly from experience.

Yes with formic acid.

I personally use sodium carbonate, it is cheap, easy to obtain, and I have experienced the speed of the action while using it.

হ্যাঁ

The result is similar to that of DMG. The procedures are different, but everyone strives to achieve the same result.

@@qtmeto Thanks for indicating what video you would like to see.

It depends on how heated it is, the point is to reach 80 degrees Celsius.

@@qwethengoldrecovery Does the pH of the acid affect the formation of palladium? Thank you for the knowledge you gave us sir.

@@AnggaSaputra-gj5xc Yes, sodium carbonate and formic acid change the pH of the solution.

@@qwethengoldrecovery thanks sir, I like you

Hoy e comprado un oxibutano,e conseguido mis primeras 4 micras de paladio.

85%

Magnetic / non-magnetic mixed.

@@qwethengoldrecovery good yeild!

@@qwethengoldrecovery just in case you are not aware...the red ones are tantalum

@@tinsoffish1810 Yes, I collected them separately, but they are very tiny so they stayed among them.

if you toking explen meneyhelp me pletinium progeres in how meny drop water u not show pletinium powder progres your vedio i waitng your next vedio i m indean

Does the material you use contain palladium?

paladyum olmadığını nasıl anladınız İsmail bey

@@gokhan2085bir kaç sefer denedim. Çıkan malzemeyi değerli madenleri alan yere götürdüm aldığım raporda paladyumun emaresi yoktu

@@raxtor3199 çok ilginç çöken hangi madenmiş peki, birşey dediler mi, boşuna emek vermeyelim

@@gokhan2085 valla hiç hatırlamıyorum ama paladyum platin veya değerli bir elementle karşılaşmadım

​@@gokhan2085 you can redissolve the powder in nitric or hydrochloric and test it with stanous chloride yourself.
