Torscot, What I have learned during the process is to treat ore with H2SO4. First time around I had treated it in the middle of the process, using iron already existed in the ore to convert any silver chlorides back to silver and then re-digest with HNO3. Effectively any nitrate salts are converted back to nitric acid.
