About :
We obtain gold from cellular communication system connectors. After disassembling the connectors, we obtained 1 kg of small and medium pins, as well as 460 grams of large ones - they were put away until better times). 1 kg of ligature was etched in nitric acid, the resulting gold husk was dissolved in a mixture of nitric acid and ammonium chloride. Then the solution was filtered, heated and some sulfamic acid was added to remove residual nitric acid. Then hydroxylamine hydrochloride was sprinkled into the solution. After restoration, the gold sediment was washed, transferred to an evaporating cup and dried. We got 2.94 g of gold. Melting was not performed, at that time there was nothing to melt with) Link to the VK page https://vk.com/id534555423 We recommend watching our previous videos: Gold from 3000 pcs. transistors - • Gold from 3000 pcs. transistors Obtaining gold from imported RFT connectors - • Obtaining gold from imported connectors...
