Gold recovery chemical formula...?


Warning, I don't know the chemical formula. GOLD STRIPPING is a ready-made chemical. Used in industrial factories, usually not sold to the general public. because it must be used with cyanide It is a prohibited and dangerous chemical. I'm just a user as well as nitric acid I don't know the chemical formula Do not ask where to buy or chemical formula. My advice is Check the people from the chemical supply store. in your country Thank you for watching our video.
