| 摘 要： | 采用球磨反应和静态水热反应对钾长石-氧化钙-氢氧化钾体系提钾工艺进行了研究,结果显示：温度对钾长石提钾有较大的影响,静态水热反应提钾效果优于球磨反应.较适宜的静态水热反应工艺条件为：m（氧化钙）/m（钾长石）为1.5,m（钾长石）/m（氢氧化钾）为15,恒温220℃下反应10h,每克钾长石加水量为20 mL,此时钾溶出率达到90％以上. |

| Abstract: | The potassium extraction process of potassium system is studied by ball milling reaction and hydrothermat effect of temperature on potassium extraction is significant; feldspar-calcium oxide-potassium hydroxide reaction process. The results show that： the the hydrothermal reaction process is better than ball milling reaction for extraction of potassium. In the appropriate process conditions of the hydrothermal reaction： the mass ratio of calcium oxide to feldspar of 1.5, mass ratio of potassium feldspar to potassium hydroxide of 15, the temperature of 220 ℃ and the time of 10 h, adding 20 mL water per gram potassium feldspar, the dissolution rate of potassium can reach more than 90%. |
| Keywords: | potassium feldspar calcium oxide potassium hydroxide ball milling reaction hydrothermal reaction |
