| titleOfInvention | Method for taking gold from exhausted electrolytes and cleaning waters |
| abstract | This method will find application in the field of electroplating and ore mining. It features low consumption of ion-exchange resins, high gold levels per volume unit of resin, and a minimum of operational steps. The method comprises the following: Spent electrolytes or washing fluids containing auro and auri ions are passed through a layer of resin in its basic or saline form. After saturation, the resin is treated with a solution consisting of: sodium hydroxide and formaldehyde at a ratio of 1:0.5 to 1:1 and a concentration of 4-500 g/l, while the quantity of added solution amounts to 50-100 % of the resin volume. The solution is discharged into a collecting vessel and reused after adjustment of its chemical composition and additional quantities of electrolytes or water are flushed with the treated resin. After repeating the same cycle 2-3 times, the resin is dried, heated up to 400-500 degrees C, mixed with borax and sodium carbonate and heated once again up to the melting point of gold. |
