In this first video of the series, I help out a person from Taiwan who has a large amount of e-waste plated with palladium. He asked me to figure out a process he could use to recover the palladium. He sent me a sample of the material to experiment with. Let's see what I can come up with... Please visit my blog at mdpub.com/Urban... for more information.

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

Maybe...

Palladium recovery is going to make a good series

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

Fascinating experiment Mike. 👍

@markmatt9174 3 месяца назад

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... 🤔

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

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

In electronics plating, especially on PCBs, ENIG is the most common method of gold plating. It uses an undercoating of nickle. But in cases where magnetism can influence the circuit, the nickle is substituted with palladium, thus you use a EPIG plating instead. So I doubt there's both nickle and palladium in this (although it might be these scraps are from something completely different :P)

@nohara7633 3 месяца назад

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

@kwinterburn 3 месяца назад

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

@mattlevesque5927 3 месяца назад

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

@johannesdesloper8434 3 месяца назад

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

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!

@user-tl7tz9lb9w 3 месяца назад

the strip was gold plated, after the product is make, then the edges been cut off, it was going to recycle, but someone steal it out and refine gold from it, after the gold is refined, the Pd is remain.

@rockman531 3 месяца назад

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

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

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

@empirefinds 2 месяца назад

Hydrochloric acid and hydrogen peroxide 1ml to 1cl this will release the foils with no copper contamination awesome episode brother just got 5 mins left and I will watch part 2 awesome

@goldensadventures1229 3 месяца назад

I thinking some fire may be involved too. Good video

@Route66GoldHound 3 месяца назад

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

@williamjohnson2105 3 месяца назад

the acid peroxide method might be the easiest to employ, if time is not a big factor

@MickNailZ 3 месяца назад

Have you thought of trying eco goldex

@Alex-kp3hr 3 месяца назад

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.

@robertsletten7466 3 месяца назад

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

@user-tl7tz9lb9w 2 месяца назад

I did that by using AP solution, but the separation is killing me lol, and some of them just didn't come off.😢

@Gin-toki 2 месяца назад

Could Ferric Chloride be used to remove the copper but leaving the paladium behind? It's great at removing copper from PCBs.

@omegageek64 2 месяца назад

That would probably work. Good idea.

@reverendtfg6802 3 месяца назад

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

@omegageek64 3 месяца назад

I thought about that. Eco-Goldex is difficult to get in a lot of places. I don't know if it would be available in Taiwan. Plus there are a lot of steps to using Eco-Goldex, and it can be expensive. I'm always looking for easier and less expensive ways to do things.

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 😅
