a well-known two-step method of refining in nitric acid and aqua regia. New - a scrubber for neutralization of acidic gases and vapors. You can safely work without protective mask in closed spaces
1. I know of no two step process to refine gold. I think you are way over simplifying things.
2. Before you refine, you must recover gold, how are you doing that?
3. Have you personally used your system to recover and refine gold, yourself? And how long before the equipment failed?
4. Your system looks extremely unsafe. If you were to use this in an enclosed area, and it failed, NOx would be released into whatever enclosed area (apartment I think you suggested) thus putting every
living creature in the same area at risk, to the point of even possible death. How can you be sure your system is not putting peoples lives at risk.
5. Your process cannot cover all types of precious metal scrap, you make no mention as to what specifically it is meant to refine, nor do you talk about recovering.
6. Some of your easily replaceable parts will fail not because of normal wear and tear, but rather because they were not specifically designed to resist corrosive gases and fumes. Like the vacuum.
7. Does hot acid at any time come into contact with plastic? If so, you have really made a recipe for potential disaster.
8. Is there any technical proof or data that proves this is safe to use, or proves your claims. It doesn't seem to me that you have followed any industry standards.
This is just a quick and dirty laundry list of issues I could think of right off the top of my head. I fear for the safety of anyone who dare uses this system, specially in an enclosed area.
I would also like to know what your background is, and how you can make these claims. Do you recover and refine yourself? Are you an engineer? A Chemist? How long have you been recovering and refining precious metals? Any experience you might have that can validate or back your claims?
