摘　　要：本文以含锌53.35%、含铁13.51%及铁酸锌13.97%的锌焙砂为原料,在对锌焙砂粒度分析、X-荧光多元素半定量分析、XRD分析及锌铁物相分析基础上,采用硫酸做浸出剂,研究始酸浓度、液固比、搅拌速度、浸出温度、浸出时间等因素对浸出渣物性的影响。结果表明,获取高含量ZnFe_2O_4浸出产品的试验条件为:始酸浓度100 g/L、液固比8∶1、搅拌速度400 r/min、浸出温度75℃、浸出时间120 min。In this paper,zinc calcine with 53. 35%Zn,13. 51%Fe and 13. 97%zinc ferrite as raw materials was studied by the analysis of granularity,X-ray fluorescence multi-element semi-quantitative,XRD and zinc iron phase.The influence of sulfuric acid concentration,solid-liquid ratio,stirring speed,leaching temperature and leaching time was studied on leaching residue properties.The results show that the leaching conditions obtained high content ZnFe2O4 is initial acid concentration100 g/L,liquid-solid ratio 8 ∶ 1,stirring speed 400 rpm,leaching temperature 75℃ and leaching time 120 min.
