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0150~0045 mm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60 min、搅拌速度为300 r/min;该浸出反应符合未反应缩核模型,其表观活化能Ea为53555 kJ/mol。

Abstract: In order to provide reference for efficiently recovery of indium from Indium-bearing zinc ferrite,the processing conditions for leaching of synthesis indium-bearing zinc ferrite in sulphuric 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 ℃,leaching time is 60 min,and stirring speed is 300 r/min. The indium leaching reaction of IBZF in sulfuric acid fits the un-reacted shrinking core model with the apparent activation energy Ea of 53.555 kJ/mol.
