| Abstract: |
| To aim at leaching process of zinc sulfide in Mn2+ catalyst system,investigate the effect factors on leaching rate of zinc,such as leaching temperature,leaching time,stirring speed,liquid-solid ratio,oxygen pressure,the dosage of Mn2+.The optimum operation condition is obtained by the orthogonal experiment.The leaching rate of zinc is more than 95% under this condition. |
