Hi, Salam Aleikum
thanks for you helpful posts.
I have a question.
i have some palladium gold mix that rate of mixture is 8% palladium and 92% gold.
what is the procedure of extraction? is the same as gold with Aqua Regina and Metabisolphidsodium or another way?
Im looking forward to hearing from your guide.
Thanks for your good words.
You and use aqua regia but palladium recovery will difficult. You can refine gold with silver. All palladium will dissolve in nitric acid and then you can precipitate palladium with DMG or sodium cyanide.
You can apply for the license about these chemicals. When you will get the license then you can do this legally.
