摘　　要：研究了富铟高铁闪锌矿加压浸出铟的动力学。结果表明:铟浸出过程符合未反应核收缩模型;搅拌速度大于600r/min时对铟浸出影响不大,外扩散过程并不控制铟浸出反应;温度、压力、始酸质量浓度、矿样粒度对铟的浸出有影响,铟浸出过程受化学反应控制。根据各因素对铟的浸出影响动力学方程推导出铟浸出动力学方程。The pressure leaching kinetics of indium in sphalerite with high indium and iron was studied.The results show that leaching process of indium conforms to unreacted shrinking reaction core model.At the stirring speed over 600 r/min,there is no effect on leaching,and indium leaching reaction is not controlled by external diffusion.Temperature,pressure,initial concentration of acid and ore size affect leaching of indium,and the leaching process is controlled by chemical reaction.The leaching kinetics equation is deduced.
