| Abstract: | This paper is based on experiments,raise thettechnology of decomposing the potash fe-laspar with the sulfuric-hydrofluoric acid mixture to extract potassium. It studies a lot onthe effects about the reaction's time termperature,the concentraction of the hydrofluoric acid,of the decomposition rate of the potash feldspar,and the rcutralization's PH on the quality ofthe product-K2SO4,finds out the best technological condition. The rexultiondicat that thetotal product's tate is 85. 4 percent. |
