Abstract:
     A continuous industrial process for wet decomposition of potash feldspar to produce such products as ammonium potassium sulfate as main one, Al series and Si series comprises normal-temp low-pressure decomposition reaction of potash feldspar with inorganic acid and fluoride in stirror, calcining the resulting matter in solid phase in seperator to obtain a material containing K2SO4, Al2SO4 and active SiO2, and preparing the products, and has avantages such as less energy consumption, high comprehensive utilization rate, and decomposition rate of potash feldspar up to 93%. K2O content in ammonium potassium sulfate being 20.44%.
