| Abstract: |
| The effects of ratio of solid to liquid, leaching temperature and time on the gold leaching rate were studied by adding a proper amount of sodium hypochlorite with sodium chloride as solvent. The results show that the gold leaching rate is above 41% under the optimum conditions including leaching temperature of 50 ℃, leaching time of 3 h and ratio of solid to liquid of 4. |
