| Abstract: | On the basis of the double superphosphate production prcess conditions , the reaction behavior of potash feldspar with phosphate rock and phosphoric acid in hydrothermal reaction pot were studied .The effects of the dose of phosphoric acid , the concentration of phosphoric acid , reaction temperature , reaction time and ratios of reactants on the potassium leaching rate of potash feldspar were researched and the optimum experimental parameters were determined . The directions of fluoric ions that originally existed in the phosphate rock were discussed. |
