Hi I'm very beginner in refining precious metal and hoping that the masters here can help me with my issue. I used to refine gold using inquartation process and usually I use copper rod or plate for cementing the silver. Now I have a metal that consist of mostly gold, silver, and palladium (I have xrf analyzer). I never have any experience in refining palladium, so can you give me Any suggestion or tutorial on how to do it? FYI I am not used to aqua regia because of the lack quality of chemical needed during the process in my country and using inquartation has benefit me the most. Thank you
