Anybody ever attempted any gold plate recovery with HNO₃+3 HCl? Or know small refinery local to the triad they trust? I've been watching videos, it looks pretty straight forward - use PPE and a fume hood. I'm no chemist but I can read, comprehend, and follow directions. Found a supply house online that has all the chems I'd need minus the HCI. I ended up with about 40lbs of plated scrap, based on weight, shape, surface area, and plating thickness I'm guestimating a 0.004 yield which works out to ~2.5oz or $3800.
