Palladium From Taiwan E-Waste, Part 6

This is the 6th video in the series of working with the palladium plated scrap Joven sent me from Taiwan. Here I FINALLY get the palladium isolated. Plus there is a surprise at the end. An unexpected bonus. Watch and see... Please visit my blog at mdpub.com/Urban... for more information.

Get that gold! It’s nice that gold like to precipitate from a more dilute solution than palladium (which would rather precipitate from a more concentrated solution). Should be easy with some SMB straight into that bucket, let settle, and decant. Thanks, Mike, for bringing us along on this adventure.

Looking forward to part 7

Wow. This has been an exhausting experience, and I'm just WATCHING the process! Mad props and much respect for the amount of patience you have 👏 Looking forward to seeing the final results. Mental note to self, NEVER work with palladium, unless I need to drive myself crazy😁

Looks great. I do a lot of industrial scrapping and nickel is a valuable metal that we separate out. The alloy in our material is only like 20% nickel but I know that’s what my buyer is looking for “Ni-resist cast iron”. I wonder if there is a good way to separate the nickel from the copper? So if you SMB’d into a large bucket, filter the gold, then place in bucket with copper to get all your trace precious metals. Then place in a bucket with pure nickel in it. Wait for copper to drop out along with any possible tin/lead. Then you should have a solution with nickel and iron. Switch to a clean cementing bucket with iron in it and finally drop the nickel. Maybe. I just don’t know how long of a process that would be.

Thanks for pointing out Hoke's book being available in print! I've been hunting for it for over a year now and no luck at affordable prices. Got it ordered now :)

Cheers brother looking forward to the next episode

If I'm not mistaken you need to rinse PGM ammoniumchloride salts with saturated amoniumchloride solution in water else the PGM salts can dissolve.

Awesome video. Look forward to the next

I think I prefer that title “what is this? Part 6

[@goranaxelsson1409]

Palladium chloride is more or less insoluble in pure water, but what you have here is a sodium chloride solution and that can dissolve palladium chloride. Basically it's the chloride ions that forms a complex with the palladium chloride. PdCl2(s) + NaCl(l) -> PdCl4(2+)(l) + 2 Na(-)(l) It's the same effect when you have HCl and dissolve the PdCl2.

Hi Mike, So much chemistry - my head is spinning! Certainly looking forward to part 7! Finding gold is a wonderful bonus! Stay safe! Thumbs up! Jim

[@richardhulbert9480]

Not my method but Prospector Pete strips ram stick foils with a soldering gun. That is about the only way I can think of to remove the gold and not the palladium. Just a thought.

[@garrettmillsap]

Woo hoo! You used my suggestion or at least came to the same conclusion lol. Referring to using water to dissolve the sodium chloride in your solution

[@abeleski]

considering you are doing this as a method for somebody else who has a lot more of the material you should go after the gold so he has an idea if it is worthwhile for him to go after it and how much to expect

[@bobvines00]

Mike, do you work as a Chemist, Chemical Technician, or are you just an chemically experienced "enthusiast"? :) Also, when I visited a few weeks ago, I didn't think to look at or ask about your "fume hood system" layout. Does the exhaust go somewhere that any "heavier than air" fumes/gasses won't fall back down to where you are working? Before I retired I never paid much attention to the total fume hood systems in our Materials Lab (which included a lot of Chemists & Chemical techs, along with Metallurgists & "polymer experts" (I don't know their proper title) and I don't recall much about the fume hoods & scrubber systems in our Chemical Cleaning, Electroplating, & Conversion Coating Shops.

Self-taught chemist. Got interested in chemistry playing around with large amateur rockets in my 20s and 30s. Eventually gave up that hobby (I had too many and something had to go). Got into e-waste refining in my 50s and had to learn much new chemistry. Less likely to blow myself up with this hobby, but poisoning is always a possibility. Fume hood is home-built. The first iteration had a stack that went straight up. Found out quickly that was a bad idea since most of the fumes I make are heavier than air and fall right back down. Now I exhaust it at ground level in the side yard. Just a small patch of dead grass around the exhaust.

@46:28 making the video might be worth making, just for the sake of a video. i would watch it.

XRF analyzer sitting at Dulles airport customs. They forgot to mention that I had to pay the tax and duty.

[@shawnsmith9512]

They forgot to mention that they are in another country and you are the importer? They deal with the country they are in and you deal with the country you are importing the device into. They didn’t forget shit, import duty is on you. Don’t blame them for not know what they are not responsible for in any way. You should really take the time to understand the law you are dealing with

[@dwarvenaled]

You wanna trade me a xrf anlyser? My email is on my channel.

[@vw8796g35]

Hi mike this waste solution as there still active componant would have been possible to dissolve ic pins in it ? You know to use all possible ingrédient and save some $ ?

[@richardhulbert9480]

Hope it's wide fan. Not saying your fat or any.😂😂
