从钾长石中提取钾的研究

针对国内钾肥长期依靠进口、生产落后的状况,本文通过实验研究,基本确定了熔盐浸取法从钾长石中提钾的工艺流程,并利用平行实验和正交实验的方法,得出最佳助剂,最终确定了最佳工艺条件,为进一步扩大试验奠定了基础。

Molten Salt Leaching Method Extracting Potassium from Potash Feldspar

In view of the domestic potassium fertilizer long-term dependence import and the backward in production condition,this article through the experimental study,had basically extracted potassium from the potash feldspar by the molten salt leaching method,and obtained the best medicinal preparation as well technologic condition by parallel experimental and the orthogonal experiment method,lay the foundation for further experiment.
