I refined some metal catalyst that I had and I have about 72 grams of what I believe to be rhodium. I bought steves video and processed them accordingly and attatched is what would not go into aqua regia solution. Can anyone suggest where I can have it tested or assayed or even who may be interested in buying it. I called a couple refineries and they told me to send it in to them but i am hesitant after they told me that there is only 1 to 2 grams of pgms per catylatic converter and that there are probably alot of base metals. That was after telling them the process that I used. I used muriatic acid on the metal catlylists, I then rinsed what was left and then I proceeded with the aqua regia. I used the amonium chloride to drop the platinum and then sodium chlorate for the palledium . I then took what would not go into hot aqua regia and started another batch. This is what I have left. Any help or suggestions would be greatly appreciated
