![]() Some other places to begin learning is with the forums guide to the forum, spend some time taking the tour,, and the general reaction list, both found in the general chat section. Learn the proper way of using aqua regia, and the other methods used in recovery and refining.ĭown load Hoke's book, (found in the book section of the forum), reading it and doing the getting acquainted experiments will help tremendously to be able to understand much of what we discuss, and help you to get a better understanding of recovery and refining.įorget what you learned on the World Wide Web begin to learn the finer points of this complicated science. ![]() ![]() Then study the forum to learn how to properly recover and refine precious metals. While in the safety section, you will learn how to keep yourself and others safer from the deadly fumes and solutions, how to safely recover and refine with the dangerous chemistry involved. So that you can safely deal with the toxic solution you have now. You most likely have way too much nitric acid, and by now I suspect way too many other chemicals, and contaminates involved, trying to recover your gold from this batch can be done several ways, I think the easiest for you at this point is to cement the values with copper, rinse and dry the powders recovered, and store them in a glass jar and label them, so you know what the jar may contain when you are ready to recover and refine the values.įirst on the list of things to study is dealing with waste found in the safety section. ![]() It sounds like you found a little information on recovery and refining, and believe this science is easy, all you had to do is follow a few simple instructions and the chemistry experiment would give you back your gold. You have made the same mistake most of us have, before we found this forum, (and spent many hours to learn this science of how to properly recover and refine precious metals). by the way, im a cell phone and computer tech and I love to collect stones and gold and silver and other precious metals, im aware of the money currency and from time to time read about the money market. ![]() I separate gold pins from CPUs and cell phones as cleaned as possible, in a glass coffee containet with the gold pins I added nitric acid 42 Be 68%, I waited until there was no more reaction, collected the remaining gold flakes with a filter wash it with purified water, in a clean glass container with the gold flakes filtered and clean as possible I addedĪqua regia one part nitric acid, three parts hydrochloric acid, I let it react overnight, then I will add urea to neutralize the nitric acid until there is not more reaction, I added purified water and then when I add sodium sulfite, it starts foaming and a red orange foam starts forming but it disolves into the solution again, then I'll add more sodium sulfite and I get the same reaction, red and white foam, I followed the same directions as it's described and I get the same reaction, what I noticed the nitric acid changed to yellowish color, I used stannous chloride to detect gold and I get a light purple color in a cotton swab, this is my firs post and my first fail in gold refining, any help will he greatly appreciated. I got my hands to nitric acid 42 Be 68%, hydrochloric acid 20 Be 32%. Hi, im new to recovering gold, I read, watch videos, get the acids and safety gear. ![]()
