【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。
[Abstract]:In this paper, zinc calcine containing 53.35% zinc, 13.51% iron and 13.97% zinc ferrate was used as raw material. On the basis of X-ray diffraction (XRD) analysis and zinc iron phase analysis, the initial acid concentration and liquid-solid ratio were studied by using sulfuric acid as leaching agent. The effects of stirring rate, leaching temperature and leaching time on the physical properties of leaching slag were studied. The results show that the experimental conditions for obtaining high content ZnFe_2O_4 leaching products are as follows: initial acid concentration 100g / L, liquid-solid ratio 8: 1, stirring speed 400rpm, leaching temperature 75 鈩,
