 · I was extracting gold from old computer parts. I first removed the gold using Nitric Acid, neutralized it, and picked out the gold. I then dissolved the remaining scraps with Aqua Regia and it turned emerald green. I'm assuming I have some Copper and other impurities. I left the solution under a hood for some time and it crystallized.
