| Abstract: | The reactive system consisting of potash feldspar-phosphate rock- hydrochloric acid is studied on the effects of influencing potassium and phosphorus extraction rates, for the comprehensive utilization of potash feldspar and phosphate rock. The optimum conditions are that： with the raw materials potash feldspar and phosphate rock of size less than 0.074 ram, the mass ratio both phosphate rock and potash feldspar of 1, the hydrochloric acid （ 1＋1 ） adding amount of 5.6 mL/g potash feldspar, reaction temperature of 200 ℃, reaction time of over 70 min, the extraction rate either potassium or phosphorus can reach more than 90%. |
