| Abstract: |
| Manganese was leached from a mixed manganese ore with sucrose as reductant in sulfuric acid medium. Single factor experiments and response surface methodology were applied to analyze effects of concentrations of sucrose and sulfuric acid, leaching temperature and reaction time on manganese leaching rate. The results show that manganese leaching rate is 92.48% under the optimal conditions including 5.52 mol/L H2SO4 and 13.33 g/L sucrose for 160 min at 90 ℃. |
