The refining of gold briefly about the process, the first thing I did, as in the past video as far as possible parody of shattered stone, then dumped in a bowl - and a beaker filled with concentrated hydrochloric acid. Why is hydrochloric acid, it is the first and very important step in this generation. The hydrochloric acid solution is most of the various debris, while gold remains in place. Further still I filtered out again added with hydrochloric acid and filter placed on the tiles, adding nitric acid syringe, as shown in the video, that this time would be dissolved gold. So I boiled the stone quartz porridge one hour. And then we get a clean, bright gold-yellow solution, if it is there, of course. In my sample was, as I have done tests before. What to do next, it's easy, without suffering poured sodium metabisulphite Na2S2O5 checked and everything is ready for a few seconds, the gold stands out as a brown, heavy draft, as shown in the video, the gold out of nothing. I advise you to use only sodium metabisulphite, and nothing else. The last time I used a different agent, sodium sulphite Na2SO3, I personally do not like working with him? Its disadvantage, it is necessary to wait long for refining, and it is a very exciting moment. Also the last time I was immediately dissolved in aqua stone parody of the mixture without boiling-bag, but they were some of the reasons. And the solution is, of course, was much dirtier, which is very bad. Do not forget the same to be tested chlorine tin refining before and after, as shown on the video. After the restoration of gold surged I just a small part of tin chloride in solution. If the solution is colored, even a small part, I would add a little more pyrosulfite and waited. And I advise you to do the same, no matter what to pour the precious metal. More little information? The costs of hydrochloric acid is essential, but you will agree, a lot more gold is worth two three liters of acid. I hope this information is of interest to you, since I do not suggest you to do it, but if I answer some of the questions is only here and only for this video.
