As a suggestion if he has industrial quantities of those foils then it's probably waste from capacitor manufacturing , and they could be significantly palladium

How about dissolving the nickel and the copper off with ap solution to release the palladium foils

Had to pause right off. I took 3 years of photography. That looks like Lithographic transfer film. Similar to photographic film. It would be exposed to an image, chemically plated, then the plating of the image would be transferred to another surface. Like a kids stick on tattoo. That's the simplified version. It may not be, but it sure looks like it

Fascinating experiment Mike. 👍

Palladium could be removed by boiling it in concentrated HC.The PdCl2 could then be reduced to metalic state by cementation on copper.

Lots of great replies, looks like these parts are left over bits from a manufacturing process that makes capacitors or some electronic products. These appear to be the strips that would hold them on rolls for assembly/shipping. Someone mentioned that the gold was remo ed may have meant it was removed from the manufacturing pricess of the electronic parts... 🤔

Sound like Tom Arnold lol

I always use copper to cement the precious metals from a dirty solution. Then refine further, it might work for this situation.

Maybe when he said "the gold was removed", he meant as in "the manufacturing step originally plated gold over the Pd, but that step was removed"? They probably used an EPENIG process originally, then omitted the Au from the process when Pd price got so low compared to Gold. It wouldn't be a huge surprise if we start seeing more Pd plated stuff, with Pd being so cheap now. It used to be a pretty common plating material. Can't wait to see the yield on this stuff!

Hi Mike, if you added sulfuric acid to the nitric acid, would not the sulfuric acid oxidize the nickel layer and copper to prevent the nitric acid from dissolving it leaving only the top layer of palladium to be removed? I could be wrong.

Mike I need a porch and add on to build. Sure can use your help

You can rinse with your filtrate, save loads of waste and keeps concentration of your solutions up. Fun to see something new.

Welcome home. Now language barriers should be normal. It's my experience that women use a totally different version of English then men. Quick example how many different "fine" does your lovely bride use? Think I am safer learning Mandarin or any other languages. Oh by the way you weighed the bag 😅

Have you thought of trying eco goldex

Nitric and chlorine don't make AR, they're both oxidisers . It's hcl and chlorine that make AR

How about Burn the strips in furnace at lowest possible temp Powder the Ash n metal Put into zylon bag (like streetips uses for silver refining) Use electrolysis in copper nitrate to remove the copper. The nickel should go into solution and the palladium should be left behind in bag or sediment. This can then be refined out of any carbon from the strips with nitric/aqua regia or possibly nitric with H2O2

Hi Mike, Welcome home! Certainly a unique project! I think your 'sandwich' diagram was spot on! It will be very interesting to see how much Pd a kilo of strips will produce. Looking forward to part 2! Will you be making any videos from the last pile of scrap you brought home?? (your autopsy table is feeling neglected) :) Great video - as always! Thumbs up! Jim

Could you use HCL or HCL and Peroxide to dissolve the copper and nickel and leave the palladium and substrate behind?

I thinking some fire may be involved too. Good video

Pure tin is the best and for the small amount you need to last you a lifetime won't break the the bank.

I would think the gold was reverse electroplated. Awesome video OG 🤟🏼🫶🏼

Key board art, size thirteen method and slow motion replays. I love it

*Doesn't Eco-Goldex do palladium too? You should try that.*

Hi Mike! If that midle stuff is plastic, burn it! Like Beavis said: FIRE!!! FIRE!!!

When I first started watching I thought it would be better to incinerate the plastic then hit with hot nitric but it may be better to use a weak nitric/water mix to eat the copper and nickel but don't heat it that way the nitric should only attack the copper and nickel as they are more reactive then it would just leave the foils after that I would probably use nitric to dissolve foils and then use sodium formate to get the pd out but look on the Internet how to do that or hokes book

Mike, I'm also looking for a laptop that actually works for use in my home shop. The bigger the screen, the better. I don't need the latest & greatest processor or OS. The more I/O ports the better (parallel & serial would be great, but not required). What name do you use for your eBay store?

Mike, in your working LaserJet pile, did you have any "small" ones that are black toner only? I'm looking for an affordable one for use in making toner-transfer PCBs for projects.

I wish we had stores like these in my country

I live in the North Carolina mountains. My soil is super rocky. What do I use? Thank you sir.

Do you really think anybody’s gonna weld and create that contraction you created?

Good job white bread

Doesn't the connector have gold pins as well?

Thanks, please continue your efforts Floridian

Kinda short,no?

Love this, great job upcycling ❤

Thank you.

Hey, thank you so much for your clear and generous demonstration.

Fascinating video, thank you for sharing

Is this an area you searched during the Chase years? I kind of recall you were drawn to Colorado for searching.

Spinning liquid follows parabola. If youre after newtonian scope you need a spherical concave primary, other designs require a spherical and hyperbola convex- (cassegrain) (rc/cdk designs -elliptical conc primary). Best bet is to cast speculum alloy tin, copper in a plaster concave mold polished and then polish the mirror to a difracction standards with spinning polishers, and leather. Channel huygrns optics uses dft fringe program, camera and laser to chck final mirror

boil fingers in water till flakes are free

sodium bicarbonate.

It's not worth striping sell as is to your scrap dealer

great video. thank you for taking the time. can i ask why you use muriatic acid to bring PH back down on an accidental over-treatment, and not more waste?

You can't test your final ingot by just looking at it! You paint a touch of pure nitric on each one and if it stays white, it's pure silver. If it's slightly yellow or brown it indicates presence of copper. The darker the spot the less pure... For absolute purity you need an electolytic cell (easy to make, plenty of videos on the subject) Good luck and thanks for your videos

Trying to purify Silver that is for all practical purposes rather pure does nt click in my mind.. Unless you want silver anodes for electroplating, most silver will be alloyed with copper again to make Stirling Silver or Silver solders. I made a mini-ingot with my "cement silver" coming out of the copper ion exchange (as shown in you video) to test it with nitric acid and it came out something like 98-99 % pure enough for what I want to do with it. And OmG a fume extractor for working with 10% acid solutions? Americans are funny... Thanks for great video anyhow...

I would like to know the price of the cb radio also a fmtransmeter kits

Where is the 3th video? Did this method work?

Operation Pettycoat great movie
