| 摘 要： | 本文以含铟锌浸渣为对象，研究其在硫酸溶液中的浸出动力学。考察了搅拌转速、硫酸浓度、三价铁浓度、反应温度和矿物粒度等实验条件对铟浸出速率的影响。结果表明：其浸出过程可用没有固体产物层生成的“未反应核收缩模型”描述；浸出反应的表观活化能为 J/mol；对硫酸浓度与三价铁浓度的表观反应级数分别为0.985与-0.096；含铟锌浸渣的浸出过程受化学反应控制。

| Abstract: | This paper presented a study for leaching kinetic indium from indium-bearing zinc residue in H2SO4 solution. The shrinking core model was applied to the results of experiments investigating the effects of stirrer speed, H2SO4 concentration, ferric ion concentration, leaching temperature and particle size on indium dissolution rate. The activation energy for the leaching process was found to be J/mol. The reaction order with respect to sulfuric acid and ferric ion concentrations were approximately 0.985 and -0.096, respectively. The dissolution of indium from indium-bearing zinc residue in H2SO4 solution was found to be controlled by reaction-controlled process. |
