My English is not very good, but I'm trying. How can I get the palladium in the silver chlorate left over from the stone separation process? Please help me with this, thank you.
Welcome.My English is not very good, but I'm trying. How can I get the palladium in the silver chlorate left over from the stone separation process? Please help me with this, thank you.
Hİ . Let me be clear. I dissolve mixed gold and some PGM jewelry in aqua regia to remove precious stones. and after the gold dissolves, I filter the silver. Of course, the gold dissolved in this acid is of various carats. During this dissolution, silver chlorate comes out of the gold and I filter it. While filtering, palladium rhodium and iridium silver get stuck on the filter papers that I filter and this rate is about 5% of the silver and I want to get these pgms from this silver chlorate. I want to learn this method, thank you.Welcome.
I'm not sure I understand you.
Is this Silver Chloride from karat Gold?
If so why do you expect Palladium to be there?
Any way the safest way to do it is to cement on Copper.
Since you have processed it you nees to study these links before you proceed.
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/

Thank you for the information you provided. Here's what I do .Let me be clear.

I want to learn this method, thank you.I think you have silver chloride in an AR solution from stone recovery , if this is the case then simply filter and well rinse the silver chloride and then cement the palladium out using copper and aeration which will recovery your palladium and then convert your silver chloride back to metallic silver using the method of your choice.
How should I use copper to remove pgm from silver chloride or how should I wash it with nitric acid? I would be grateful if you explain thisI think you have silver chloride in an AR solution from stone recovery , if this is the case then simply filter and well rinse the silver chloride and then cement the palladium out using copper and aeration which will recovery your palladium and then convert your silver chloride back to metallic silver using the method of your choice.
Please get your chemicals straight. Silver Chlorate is a salt we "never" see since it is water soluble and do not form in our conditions.Hİ . Let me be clear.

Palladium dissolves easily in the AR so it will be in the solution.Thank you for the information you provided. Here's what I do .Let me be clear.
