Molten Salt Leaching Method Extracting Potassium from Potash Feldspar

LIU Wen-qiu(Hebei Energy Institute of Vocational and Technical,Tangshan 063004,Cnina)  
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.
【Key Words】： potash feldspar molten salt leaching method parallel experimental orthogonal experiment
