That is a masterpiece. Separating silver and palladium is a true pain in the arm. I tried it several times - not your process - and I never got the Pd really clean.
You could have just poured the silver solution into a container with some large pieces of copper pipe or copper plate in it. The silver would have cemented out on the copper leaving a blue copper solution behind. That copper then gets recovered by pouring it into a container containing iron pipes or plates for the copper to cement out on. Doing that takes more time, but it is a heck of a lot cheaper and the yield is the same
Your proposed method can not work properly. The ionization tendency is as follows. Cu(+0.34V) > Ag(+0.80V) > Pd(+0.92V) *Notes: H=0V It means Ag and Pd cements out simultaniously when you pour the Cu into the solution. May work properly if you drop the silver pieces into the solution instead of copper. (Needs experiment to confirm its)
I could not melt the palladium platinum powder. It did not come together in the crucible. It was in the form of small dotted particles and was swelling where it was. It remained white and chalky. I could not melt it. @@OwlTech333
Exhaust conveyor I had removed it from the catalyst, palladium and platinum became bubbles at oxygen temperature but they did not come together. It hardens and hardens.
That is electrical contact alloy for electrical relays. A much easier way to do it is to put the solution in a rbf and distill off the excess nitric acid then when most of it is gone add distilled water enough to dissolve. Next heat and add salt water to it. The silver will precipitate as a white chloride and the palladium will stay as a mix of chlorides. The rest is simple reduction or eletrotwinning. Silver can be reduced to metal with hydrogen or methane. Also the silver purity from this method is extremely high 4N or better. The contact alloy is generally 90 to 95 percent silver balance is palladium and copper. 🤓
Again one great video. One question, adind sodium carbonate until what ph? Or until clouding? Before adind Ascorbing Acid, thank you very much for all your knolege sharing with us..
Thank you so much! This sure looks like the safest route. I don’t like the idea of breathing chlorine gas. I just need to recover Palladium from Silver alloys.
Well, since you mention it, I haven't found any tin recovery from acid, piling up pcb's here and wondering if i can just have them in acid bath till tin is dilluted then wash it with water and leave it aside for other treatments. I haven't found anything to then extract the tin, since it adds a lot of the weight of any pcb it would be good to know.
You can put the pcb in hydrocloric acid, use a small platinum wire or some thing like that as a catalyst, heat on, and the tin will get dissolved. To get the tin out of the acid, use elektrolysis of the tincloride.
Just. a question. you told hydrocloric acid will dissolve palladium and the silver will not dissolve .up to here ok later palladium precipitated up to here ok later the precipitant washed with hydrocloric acid .in this time will palladıum dissolve
Hello Owltech, i just want to know is it possible recover palladium from 50% scrap silver after dissolving that scrap silver into nitric acid?? And why not you using dmg to seperate palladium from silver nitrate??
@@arte47 because when it try to percipitate the nitric and hydrochloric desolve it back to aqua regia If there is access of Hcl my be silver chloride percipitate
Great vid as well as the whole series. Thanks OwlTech!!!! How did you come across silver and palladium alloy? Edit: Oh, I see. Is it typical for relays, or is it particular kind that contains silver and palladium?
Sorry, I want to ask, isn't the palladium precipitate that you precipitated dissolved in hydrochloric acid, but why did you wash it with hydrochloric acid? please explain sir

Hi , thank you for the video to increase the ph level with sodium carbonate (what ph level has to be achived) also after that you say (adding more ascorbic acid) in which process and aprx. How many grams need to be added and what after that the ph level has to be reached.thank you

Hi thank you for your video. Can i use sodium/potassium hydroxide if the solution contain copper ? And if i Use sodium formate to reduce silver nitrate but the solutions contain copper it's ok ?
Thank you. What if I would have lead-silver-palladium-platinum in one bar? I would like to recover silver and platinum together with palladium, don’t need to separate them. Please answer King :)
Pd Hcl precipitated with sodium hydroxide is dissolved immediately. Well, Why is Pd precipitate precipitated by ascorbic acid not dissolved with Hcl? üstelik birkaç dakika da kaynatılıyor.
Pd precipitate precipitated with sodium hydroxide from palladium nitrate solution is palladium hydroxide which is soluble in HCl, and Pd precipitate precipitated with ascorbic acid is palladium metal

@@OwlTech333Hello, can hydrazine be used in palladium precipitation?
@armancarmanc5895 I think so, but never done it myself. IMHO formic acid is a safer option and much more available and affordable
Excellent work by a specialist.
Thank you!
Thank's for this very usefull video.

@@armancarmanc5895 usually pinch of borax helps, or compressing the powder beforehand
@@OwlTech333 I also added borax but it did not liquefy and collect as a single substance. It crystallized where it was and remained as small beads.

OK then, sodium formate looks very neat and easy to prepare... I will give it a shot...
I don't like adding a base randomly to nutralize a solution the better way is to do a titration process
You do cool stuff! 👍👏

Just. a question.
you told hydrocloric acid will dissolve palladium and the silver will not dissolve .up to here ok
later palladium precipitated
up to here ok
later the precipitant washed with hydrocloric acid .in this time will palladıum dissolve
10:13 these are hydrated Pd oxides which I dissolved in concentrated HCl, and @23:03 I'm adding HCl to Pd metal not oxide
You can use simply drop the copper metal into the solution instead of sodium formate to pricipitate the silver.
Why would you use sodium formate?
cheaper, faster, easier to wash, better quality
Hello Owltech, i just want to know is it possible recover palladium from 50% scrap silver after dissolving that scrap silver into nitric acid?? And why not you using dmg to seperate palladium from silver nitrate??
Hi Louis, we have grams of palladium in solution .but we can't separate the palladium. We just collect gold and silver. What can we do!!?
How do you know you have pd in solution?
You could have just hydrochloric acid to the nitrate solution and it would have gone the same
I would have ended up with a pile of AgCl if I did that

hello, what is the white crystals you add after pouring the liquid hidroxide?
Hello...If you have a mix of Ag and Pd, why not first precipitate Silver with HCl and then doing your way with KOH/Formic?
The problem is that there is extra HNO3 in the solution which stops percipitation
@@ahmedmahdi1849 Extra HNO3? Dont think extra HNO3 will avoid silver to precipitate.
@@arte47 because when it try to percipitate the nitric and hydrochloric desolve it back to aqua regia

What about separation from an ore sample? Crushed rocks containing palladium and nickel?
Can you please tell me what is best for gold recovery from CPU's, cupellation method or Aqua Regia method?
IMHO nothing beats the speed of pyrometallurgy
OwlTech, why won't you precipitate silver chloride from the original nitrate solution and be left with dissolved palladium chloride?
I think your idea is simple and better
