MoreMay 18, 2017 Hydrogen peroxide is used in the mining industry for the extraction of precious metals such as gold, platinum, and palladium. Gold extraction from natural sources, including gold rocks and gold ores, can be done by leaching the gold concentrate or crushed gold rocks, in a solution of hydrogen peroxide and hydrochloric acid.
MoreI wonder if making crude Nitric acid with 31 percent Hydrochloric acid and Sodium Nitrate to dissolve more gold would work? It would be quite expensive 60 dollars for 100 g Sodium Nitrate on Ebay. Also, HCl + H202 did dissolve gold I plated with it! You can clearly see the gold.
MoreMay 08, 2014 The University of Nottingham published a video showing gold dissolve into aqua regia (a mixture of nitric acid and hydrochloric acid). Aqua Regia is a mixture of two acids, hydrochloric acid and nitric acid. Now the exciting thing about Aqua Regia is that neither of the two acids by themselves can dissolve gold.Nitric acid doesn’t really react with gold very much at all, and HCl, hydrogen ...
