摘　　要：为了给富铟铁酸锌中铟的高效回收提供参考，以铟浸出率为评价指标，研究了人工合成富铟铁酸锌硫酸浸出的工艺条件及其动力学模型。结果表明：合成富铟铁酸锌的粒度在0．150～0．04mm范围内变化对铟浸出率影响较小，浸出反应温度、浸出时间、搅拌速度对铟浸出率影响较大，较理想的浸出反应温度为85℃、浸出时间为60min、搅拌速度为300r/min；该浸出反应符合未反应缩核模型，其表观活化能Ea为53．555kJ／mol。In order to provide reference for efficiently recovery of indium from Indium-bearing zinc ferrite, the process- ing conditions for leaching of synthesis indium-bearing zinc ferrite in sulphurie acid and its leaching kinetics model were studied with the indium leaching rate as index. The results showed that IBZF within range of 0. 150 - 0. 045 mm in particle size had little effect on indium, but leaching temperature,leaching time and stirring speed greatly impacted on leaching rate of indium. The ideal leaching temperature is 85 ~C ,leaching time is 60 rain, and stirring speed is 300 r/rain. The indi- um leaching reaction of IBZF in sulfuric acid fits the un-reacted shrinking core model with the apparent activation energy Ea of 53. 555 k J/mol.
