- In this third video of the series, I continue working with the palladium plated E-Waste sent to me by Joven in Taiwan. Here I convert the palladium back to metal and calculate a surprising yield of palladium. How much did I get? Watch and see...

Excellent video bro
Nice! Looking forward to seeing you scale up the process.
Nice result Mike!
im ready for part four.
Hi Mike, Great results! Twice what I thought you'd get. Thanks for sharing your research & knowledge with us! Wonderful video series! Thumbs up! Be safe. Have a great day! Jim
Excellent result, I am glad the formic reduction worked well! I am surprised the copper cementation went so badly though, classic case of practical chem. behaviour not obeying the theoretical behaviour.
Thats a surprising yield, I am very curious to what this material is from, do update us if you find out!
I have found that boiling is an excellent way to agglomerate small particles of most metals, the Pd has a decent purity to have done that! I would say an additional boil in 10% dilute sulfuric should increase purity and assist in agglomeration of particles. Also, the formic reduction would have been faster in a concentrated solution, so for larger batches I would suggest: after initial extraction drop everything on zinc or aluminium; wash Zn/Al out with a dilute HCl boil; redissolve in nitric or AR so the Pd is concentrated; formic reduction and same process with additional dilute sulfuric boil. This should be faster and more efficient.
Excited to see where you go with this next, keep up the good work.
Awesome episode brother.
nice, could you try by using Eco-Goldex, if only for Educational-Purposus, taking Out-Side-Layer (only) may be 'efficient' ...
You could just cement base metals with pgm if you need to. It is so much easier to separate finely divided metals than an alloy or even plating.
Just boil in an acid after that your desired pgm isn't soluble in. All those finely divided base metals should clean up easily.
Pathetic boiling ❤
Note to YT : Every body use Corning ware dishes 2-4 dollars at goodwill.
Good job Mike
You can let it set to cement out but if you put some electrodes to hurryup the process , the recyclers don't wait
Palladium nitrate is an orange chemical. Add some HCl to drop out the silver. Then I usually use ammonia to make a sparingly soluble complex of PdCl2(NH2)2 it is a pale yellow salt. It helps to distill off excess nitric acid to make the chemistry more efficient.
Too bad this wasn't available back in 2020 oe 2021 when Pd was like $4000 an oz! Still an amazing yield!
Excellent stuff 👌
hmm, Sreetips cements PGM's with Zinc I think that comes from Hoke's book.
Yeah that's the fun and the horror of chemistry huh? Practice and theory are really 2 different things.
Can you do a stanous chloride test for copper ?
It doesn't seem to work for copper.
I got a good drop from adding bleech
I'll guess 20grams after done
*2 kilos @ 1% recovery is like 500-600 bucks of palladium, no?*
At this point, how pure do you think it is?
As a guess, I'd say better than 99%. Probably still some copper and nickel in it. Someone in the comments suggested there could be some silver in it too. I wish I had easy access to XRF testing.
I think 990 is industry standard for bullion grade for PGMs. They are hard to get a purity beyond that.
