Gold and Platinum Group Metals Recovery from My Stockpot Pt. 6

In this 6th and last video of the series, I continue processing material from my stock pot to recover gold and PGMs. Here I process the palladium salts I've collected in the last several videos into palladium metal sponge. I also go back to the remains of the original stockpot material to test it for the presence of rhodium, at the request of several viewers who think my stannous chloride tests have been hinting at the presence of rhodium. Is there any? Watch and see. Please visit the Urban Gold Mining section of my web site at http://mdpub.com/UrbanGoldMining/ for more information.
