2 years ago I dissolved 2.8 kg of Silver Dutch coins with 78% Ag. After everything went well and I had a little over 2kg of silver cement, I was left with over 10 L of fluids.
a 5 L jerrycan with a clear blue nitric wash
and 5 L jerrycan with a more greenish nitric wash
and more dilluted nitric washes I added to my waste pot, cementing the copper.
there is a good chance it might contain PMG's so I wanted to ask you guys how best to pursue this. I have only 10 gr of DMG enough for testing, but I do have 1 L of 85% formic acid and about 200 gr of Ammoniumchloride, and all the liquids might still contain a few grams of silver.
I was thinking to first get the silver out in the form of AgCl, then test the remaining liquid with DMG.
And once the silver is out, add some in hot water dissolved SMB to precipitate the Pd, or perhaps bubble the SMB gas in while heating it ?
Just want to reduce my waste pile, still have to sort, test and reduce about 20 liters of different waste materials containing, either gold, silver or PMG's
