Abstract
Potassium extracting process from potash feldspar by fused sodium chloride and calcium chloride was studied.The results show that the optimal reaction conditions corresponded to different solvent and the reaction temperature change from 850℃ to 1 000℃.The quality ratio of sodium chloride and calcium chloride to potash feldspar are 1.5 and 1.9 respectively.This study will provide fundamental data for the extracting potassium from insoluble potash ore.
