2010-11-16 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. Is there any easy way to save the Gold?
Read MoreIn stark contrast, the Aqua Regia process enables you to recover between 90 percent and 95 percent of the gold only. The acid mixture reacts quickly with gold and causes a small drop in its volume. Clean the computer parts with golds, remove all outer covering and drop the pieces into a glass trough containing Aqua Regia.
