Some pictures on Refining Palladium concentrates.
I used the outlined process provided by our fellow member of the forum "4metals"
(additional steps that are marked with "***" and start with "▪" are not from the original steps but are additional steps that may improve this process)

let's start with the first three steps;
▪ Calculate and add, stoichiometrically half of the needed amount to dissolve Palladium and add the remaining half in increments, cease addition when no more reaction occurs. It's not easy to Dennoxx a nitrate solution without HCl.***
• Digest the impure palladium metal in 50% nitric / distilled water.
▪ Evaporate solution down to 10ml-15ml of solution per gram of Palladium.***
• Raise the pH to anywhere between 1 and 2 with NH4OH
▪ Evaporate solution down to 10ml-15ml of solution per gram of Palladium.***
• Filter the solution to remove any turbidity or sediment, which may be AgCl.
