摘要
溶剂萃取是一种高效的分离方法 ,投资少 ,无污染。应用萃取富集、分离、提纯 ,可以由矿石直接生产金属无机盐 ,纯度高、成本低。将萃取用于无机盐制备开创出许多新型高效流程。利用萃取技术开发、改进的许多碱土金属无机盐生产流程可提高回收率和产品纯度、降低生产成本。
Solvent extraction is a high efficient,low investment and no pollution separation method.The inorganic chemicals with high purity and low cost directly from ores can be produced through the concentration,separation and purification of solvent extractions.Many new high efficient processes of preparating inorganic chemicals have been created by using solvent extraction.The processes of producing alkaline earth element compounds,which have been developed or improved by solvent extraction,offer the possibility to upgrade the recovery and the purity of the products,and lower the processing cost.
