在湿法炼锌中,铁、锌分离是一个重要的工艺过程,在传统的湿法炼锌工艺中,是采用水解中和法来达到除铁的目的。此工艺的致命缺点是胶体Fe(OH)_3不易沉淀、过滤,锌回收率低等。近年来人们采用高温高酸浸出、黄钾铁矾除铁工艺较好地解决了这
In wet zinc smelting, iron and zinc separation is an important process. In the traditional wet zinc smelting process, the purpose of iron removal is achieved by the hydrolysis neutralization method. The fatal disadvantage of this process is colloidal Fe (OH) _3 is not easy precipitation, filtration, zinc recovery rate is low. In recent years, people use high temperature and high acid leaching, jarosite iron removal process a better solution to this
