I'll buy your palladium. Don't bother melting it. It's easier for me to take a sample of the powder and run ICP-AES on it that way.

If you're trying to melt it, get a high back alumina crucible and preferably go at it with an oxyhydrogen torch. Any oxyfuel torch will easily make enough heat to melt platinum or palladium. It just depends on tip and flow rate. That's why I recommend a high back alumina melting dish so that it's much harder for your powder to blow away.

The reason why, the true reason, that carbon-based fuels like MAPP, acetylene, propane, and natural gas aren't recommended is this:

Palladium oxidizes. Platinum does not. You can usually get away melting platinum with oxyacetylene if you keep it lean at all times. You can't with palladium. Palladium has a problem that's kind of like silver's--it absorbs oxygen and fuel gases when molten and tends to spit if you don't know what you're doing. Remember well that these metals are catalytic--so any gas in a rich flame that hits the palladium is going to be split into hydrogen and carbon on the surface of the palladium. The carbon will migrate into the piece and give it a shiny gray-black look. Palladium has to be cooled below red heat in a reducing flame, and the only flame suitable for that is a hydrogen flame.

Hi Lou, I have Palladium for sale, how do I get more details
 
II have About 3.5lbs of silver alloyed with gold testing positive 22k. I've collected so far 36.56grams of MLCCs(palladium+silver)From E-waste recycling. I was planning on crushing the mlccs to powder and then melt them all together. Lol. But after reading all of this. Im kinda wondering what would be best for me to do. My goal was to alloy palladium plated w-ite gold 18k then sale it to my local jewelry store. And tips or advice on what any of you would do to get the max payout in my position. Just a guy who made an diy furnice. Using propane gas through a map gas torch head...please any advice would be amazing. I don't want to move forward until I know I'm not gonna mess up and ruin a potential great payout. . Thank you for reading. Looking forward to any responses.

Welcome to us.

First and foremost most MLCCs are not containing Silver nor Pd.
How and where did you find these?
Next if they contain Ag plus Pd the only way to separate them will be with Chemistry and Pd dissolved in acids are very toxic.

Best to study first:

We ask our new members to do 3 things.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: https://goldrefiningforum.com/phpBB3/viewtopic.php?f=54&t=19798
2. Then read the safety section of the forum: https://goldrefiningforum.com/forums/safety.47/
3. And then read about "Dealing with waste" in the forum: https://goldrefiningforum.com/threads/dealing-with-waste.10539/

Ive One a lot of research before commenting I know that you need hydrochloric acid and nitric acid to separate the palladium in Platinum from the mlcc. I've done a lot of research on finding out what are the correct mlcc that contain palladium and platinum and I've accumulated a numerous amount of circuit boards from different computers and I've scraped only the mlcc's containing platinum in palladium which are the light brown silver looking MLcc's. I've at least 20 different videos on how to chemically do this process and I understand that it is a dangerous process not done correctly that's one reason why I wanted to get any advice from you guys

Your post indicate you still need to do more research.
When you have read the links I provided you with, you can find a magnet and separate the MLCCs.
The magnetic ones contain Nickel and maybe a tiny amount of Silver.
The non magnetic ones can contain some Pd and Silver , hardly any if any at all contain Pt, unless it is very old or are Military/Space equipment.

The best course of action is then to smelt them to a button with Copper or Lead as collector.

Aha! Someone who has done their homework. Nice one. This is one of the best ways to get a much higher percentage of Noble Metal MLCC in your mix. Incidentally they also tend to be wider and flatter too.

I'll add an edit. This applies mostly to western ones. Soviet bloc and some aerospace applications are darker. The magnet approach works but within limits - you can use too powerful a magnet and pull out the good with the bad if you're not careful because Nickel end caps are ferromagnetic. So use a weak magnet if you take this approach and certainly not a rare earth one.
