摘要
海绿石是一种富钾、富铁的含水层状铝硅酸盐矿物,由于形成环境和矿物成熟度存在差异,其矿物学特征变化较大。本文总结了海绿石结晶形貌、化学组成和晶体结构特征,介绍了海绿石制备钾肥的工艺技术方法和海绿石在处理含重金属离子废水方面的应用。采用直接酸浸法从海绿石中提取K2O,反应条件温和,环境相容性好,是海绿石工业应用的发展方向。
Glauconite is a kind of hydrous-layered aluminium silicate mineral,which is rich in potassium and iron.The mineralogical characteristics of glauconite are quite different because of variation in their environment and mineral maturity.The detailed morphology,chemical composition and crystal structure of glauconite and its application in preparation of potash fertilizer and treatment wastewater containing heavy metal ions are introduced in the paper.The direct acid leaching for extracting K2 O from glauconite features mild reaction conditions and friendly environment and will have a good prospect in industrial application.
