| titleOfInvention | Method of separate extraction of gold and silver from solutions |
| abstract | FIELD: chemical technology; methods of separation and concentration. n SUBSTANCE: proposed method includes joint extraction of gold (III) and silver (I) from thiocyanate solutions followed by complete selective separation. Proposed method includes extraction of gold and silver from solution by sorption on anionite followed by separation through stepped desorption in thiocarbamide solution in sulfuric acid. Sorption of gold (III) and silver (I) is performed from thiocyanate solutions on anionite AH-25; subsequent separation by stepped desorption is carried out in thiocarbamide solution in 0.3-0.5 M H 2 SO 4 at concentration of thiocarbamide from 30 to 50 mg/l for silver and 80 to 100 mg/l for gold. n EFFECT: acceleration of method. n 1 dwg, 2 tbl, 4 ex |
