So, i just tried to run my first batch if gold filled scrap. I dissolved out all the base metals with dilute nitric acid and recovered the foils. Put the foils into aqua regia, filtered it and attempted to precipitate it using stump out by bonide. This is only my second time refining gold and the first run was with inquarted gold. That worked out great! This current batch turned brown like normal but without any fizzing reaction, even after 4-5 spoon fulls.
This was only 200 grams of gold filled scrap. It did end up having some karat gold in it that i separated after the nitric treatments. What gives? Should i keep adding smb? Did i do some thing wrong?
