Palladium From Taiwan E-Waste, Part 7
Вставка
- Опубліковано 29 вер 2024
- In this 7th and final video of the series, I finally finish recovering the palladium from Joven's palladium plated strips. It's been along and hard-fought battle, and it's not over yet. I have a lot of trouble getting to the end. Watch and see... Please visit my blog at mdpub.com/Urban... for more information.

80celcius and above is the temp needed, the hotter the more reactive. The problem with your formate reduction was the heat and you added the whole lot in one go getting the reducing reaction all at once. It's like nitric acid and must be added in small doses and allowed time to react and reduce before adding more.
Never boil anything whether reducing or washing powder, there's a massive difference in what happens between boiling/ bumping and a hot strong reaction that looks like it boiling but isn't.
Boiling the powder after reducing has sent some of your Pd powder colloidal.
Next time use sodium formate, made with sodium carbonate (not bi-carb) and formic acid. Less solution
Pd powder looks like a lot but isn't so dont feel discouraged. But I followed this Pd series and there was a lot of mistakes to recap and do differently next time. Until then Mike
Take care
Some observations I'd like to make. Consider it constructive criticism.
Insulate your melting dish with a bed of cerwool. This helps the dish heat up more evenly and get hotter.
You had too much gas flow with your flame. I don't think the torch cutting head is proper for melting PMs.
You'll want high heat but not the fast gas flow. It looked like when the Pd melted, it was blown away from the flame.
I also feel you had enough reagent there in the first round to do the whole batch and not just half. Add smaller amounts and once the colour disappears from the solution, test with stannous and, if clear, you can safely assume all the metal had dropped.
Thanks for the videos Mike, I will need this to help me with my ever growing black powders one day
Thanks for the advice. I always welcome constructive criticism.
Awesome 😊 the struggle is real my friend !!! My gold doesn't mind having other PMGs in it for just that reason right here 😅
Mike YOU have my permission to go back on vacation! THANK YOU SO MUCH FOR SHOWING THE #fails. My oh my it was ENTERTAINING and had me ROFLMAO! REMEMBER your booboos most likely prevent ME FROM MAKING THE SAME MISTAKES. THANK YOU!
Wow. I could definitely hear the dejection and disappointment in your voice at the end. After this, I imagine working with colloidal and dirty gold solutions is going to seem like a walk in the park. And as you mentioned, the palladium is not gone, just waiting. Waiting to give you another headache!😀 If I ever end up with a bunch of potential palladium, I will 1) send it to you to have fun with and use for content, or 2) send it to my worst enemy without telling them exactly what it is and let them experience the "joy", or 3) sell it on eBay. In any case, I don't think I will ever try getting the palladium, unless of course someone comes up with a way that even a lunkhead like me can follow (from the sounds of it, this will never happen!)😁. But seriously, I do hope all goes well with getting the palladium (and platinum and rhodium) once you process the stock pot and filters/rags in the future. Looking forward to seeing your next video!! Thank you for fighting through to the end!
I don’t enjoy the idea of smelting, and that seems to be the only reasonable solution for PGMs. I’ll leave the smelting to MBMMLLC
😮 this is why I love your channel I use to watch the other guy but since I discovered your channel it's now my favorite channel in all of UA-cam land keep the video's coming don't change a thing we are all human. Most of us anyway 😅
I felt bad about that boilover, things were going real good, and then the disappointing recovery. But all was not lost we did get to see some nice palladium metal. Great effort Mike. 👍
Hey your blooper videos are quite popular. I think we may see that again. But yikes.
Yeah, I really like your vids, but it's time to upgrade the sound quality I think.
Another good one for the blooper reel! LOL
But you learn form everything so your rags/stock pot should go a lot better!
I am having the exact same issue with my torch (cutting torch oxy/acet) what are you looking at for a hotter torch?
are you still sure this chinese-powder-from-canada is 'more of a hassle' ...
I got a bunch of raw stuff dunno whats all in it but you could refine some if you want. Practice makes perfect.
@32:47 oh boy! omg! why!? how did we all not see this coming?
Did you wipe down the inside of the fume hood and the hot plate?
Yep. Going to be a lot of palladium the next time I process my rags and filters.
When ur done use zinc powder to get the rest the stoc pot
Hahaha the fly weighed 20 milligram?
cant wait for the next one. i enjoy this stuff.
You didn't put ammonia in your stock pot did you?
Watching you add everything at once, I was just sitting back WAITING for that boilover to start. The problem was the density of the two solutions not mixing right away. Once everything started to mix, you got an exothermic reaction. Hopefully there was minimal loss and you were able to recover it all.
Sucks it’s so much work to refine it again once recovered, but at least it didn’t disappear 😅
Great video well done
Live and learn i guess.
Honest question. Do you really want to save the filters with you gold filters. I would think it will contaminate you future gold recovery? I would save it separate or write it off as hey I got the lions share and toss them in the trash.
Gold and palladium are easy enough to separate. As you can see, palladium is difficult and gold is easy.
This is why I don’t mess with PGMs as a hobbyist, I’ve watched both you and sreetips struggle with them and it’s just not worth it. Best left to the large refineries imo. Thank you for sharing your struggles, we all learn from them!
Mike, what fuel gas were you using in this video? Thumbs up, especially for sharing mistakes made along the way to the end of this series.
If copper is also present in the solution with palladium, will the palladium come out pure?
i really enjoy all of your videos man.. i've learned quite a bit from you as well!!!
Been waiting for the final results 😊
I would use the clear partly spent ammonium solution poured off to start the 2nd batch. No point leaving it wasted 😮 wondering if excess Ammonia is causing the foaming while boiling
Hi Mike, Can only think of one word...ouch! Nice to know that besides some palladium - there's a chance for platinum & gold from the filters & waste bucket. Thanks for sharing this adventure with us! We all learned something! Thumbs up! Jim
It's platinum lol hahaha
That's exactly the luck I have
2831°f melting point of paladium. 5730°f how hot an oxygen acetylene cutting torch can get (5600°f-6000°f).....WHY DIDN'T YOU PUSH DOWN ON THE TRIGGER TO GET THE THE EXTRA HEAT OF THE CUTTING TORCH OF THE EQUIPMENT YOU WERE USING? 😢 Now go take welding class. 🫣🥴
That's not exactly how it works. The trigger blows extra oxygen out which is useful for cutting steel. It doesn't add heat. I was using the wrong tip.
Thank you Mr Magoo here is weird he has no clue what he's doing huh now platinum a torch burly or if you don't have a powerful one will not melt it down and red salt right dude is platinum the palladium salt is yellow but even his camera is Mr Magoo cannot see it's blurry
@@omegageek64hahaha Mr Magoo sounds like Kermit da frog lmao
