| Abstract: |
| Advance of study on improvement of thiosulfate stability in gold leaching was described .Including the Standard ammonia-thiosulfate - copper system and other oxidants apart from copper and ammonia in thiosulfate solutions. The The effect of chelant，sulphur species and controlling oxygen addition on the Standard ammonia-thiosulfate - copper system were described. The alternative of copper (II) ammine complexe with ferric oxalate and Ferric EDTA were also reviewed. |
