last night I boiled about 260g of gold filled scrap in nitric acid. I slowly introduced the nitric acid and in total added about 780 mL of nitric. I let the solution cool and settle over night.
I wake up and the solution is blue but there is a lot of blue sludge at the bottom of the beaker. The gold foils are still present, but there is a lot more of this sludge, which I do not see in most gold filled refining videos
Any thoughts to what this is?
