| Title |
Leaching of gold in acid thiourea-thiocyanate solutions using ferric sulfate as oxidant |
| Date |
2011-01-01 |
| Description |
The leaching of gold in ferric-thiourea-thiocyanate solutions has been studied by the rotating-disk technique. The effects of initial concentrations of ferric, thiourea (Tu), thiocyanate, temperature and pH value on gold leaching rate were studied. Determinations of apparent activation energy indicate that the process was controlled by a combination of chemical reaction and diffusion in the mixed lixiviant system. The gold leaching rate in the mixed ligand solution is higher than either lixiviant alone, even the sum of individual lixiviant. In the presence of thiourea, thiocyanate shows considerable stability towards oxidation. |
