| 摘 要： | 采用三电极体系,以闪锌矿悬浮矿浆为对象,研究浸出过程的电化学行为。结果表明,浸出过程存在中间产物H2S,铁离子对闪锌矿的直接氧化作用不容忽视,体系中无铁离子存在时,O2对闪锌矿浸出的作用有限,氯化物对闪锌矿浸出过程有促进效果。 |

| Abstract: | The electrochemical behavior of the sphalerite leaching process is investigated with suspending slurry of sphalerite by the three-electrode method.The results show that H_2S appears as the intermediate product in the leaching process.The role of ferric ions played in the leaching process is not negligible,since the oxidation of the sphalerite by oxygen is poor while no ferric ions in leaching medium.The presence of chloride can intensify the sphalerite leaching process. |
