中文摘要: 湿法炼锌工艺过程中赤铁矿法沉铁技术是一种沉淀渣量小、分离效率高的锌、铁分离方法。针对湿法炼锌工艺过程中赤铁矿法沉铁技术开展了硫酸亚铁的氧化水解沉淀行为的研究,考察了时间、酸度、温度、硫酸盐浓度、晶种返回量等主要因素对赤铁矿法沉铁效果的影响、沉淀产物的析出特性和物相表征。
Abstract:The hematite precipitation process for removing iron is an effective way to realize high efficient separation of zinc and iron in hydrometallurgical zinc process. This study considered the oxidation hydrolysis precipitation behavior of ferrous sulfate during hematite precipitation for iron removal. Studied the precipitation characteristics and phase characterization of the precipitation product and the effect of time, acidity, temperature, sulfate concentration and the amount of return precipitates, which as seed crystal, on hematite precipitation process for removing iron.
