摘　　要：研究了从氧化锌烟尘中加压浸出铟的动力学,考察了温度、初始硫酸浓度、压力对铟浸出率的影响。结果表明,反应符合未反应核收缩模型,浸出反应活化能为14.7kJ/mol,表观反应级数为0.539 95,可以判断铟浸出过程为混合控制。The pressure leaching kinetics of indium in zinc oxide dust was studied.The influence of temperature,initial sulfuric acid concentration,pressure on leaching of indium were examined.The leaching reaction is found to belong to shrinking core model without solid product layer.The calculated activation energy of leaching reaction is 14.7kJ/mol,apparent reaction order is 0.539 95.The leaching process of indium is mixed control.
