ВЫТАЩИЛ ЗОЛОТО ИЗ ~ 30 КИЕВСКИХ РАЗЪЕМОВ...! ЮБИЛЕЙ КАНАЛА - 10 ЛЕТ

The video shows the process of gold extraction from 30 Kyiv connectors. After removing the gold-plated contacts from the plexiglass, the contacts were chemically treated to remove solder and then heat-treated to more rapidly dissolve the base in an aqueous nitric acid solution. The resulting gold foil was then dissolved in a mixture of hydrochloric acid and nitric acid (aka "aqua regia"). After filtering the resulting solution, the gold was subjected to primary gold reduction. Purification of the resulting gold with a selective reducing agent yielded a completely pure precipitate of spongy gold, which, after drying, was fused into a 999-carat gold bead.
