I did a pour off the 1st and attempted a second which that's when I noticed the lack of reaction with the nitric. Should I have left the shot in the second solution for a period of time anyways?
What strength of nitric / water did you use for the parting? Generally it is effective to start with 2 parts DI water to 1 part Nitric Acid. When that acid is spent, decant the acid and replace it with 1:1 acid to DI water. Both should be heated, the second may or may not appear to be reacting but give it time anyway.
It is often necessary to break up the chunks with a stirring rod to help the acid penetrate better. When assaying and the ratio is 3:1 gold to silver, it is often better to roll the inquarted alloy flat before parting for more surface area. This is quite a bit of work for large lots so adding a little extra silver to make the acid penetrate better is the easier route.
