| 摘 要： | 建立钾长石-硫酸常压水热反应体系,考查了反应温度、硫酸浓度、固液比以及反应时间对反应过程的影响。实验结果表明,硫酸能够分解钾长石,但常压下,硫酸分解钾长石溶出率只能在12%左右。在仅有硫酸和钾长石的常压体系下很难得到较高的钾溶出率。

| Abstract: | By establishing potassium feldspar-sulfuric acid atmosphere pressure hydrothermal reaction system,we studied how reaction temperature,acid concentration,solid-liquid ratio and reaction time impact on reaction process.The results showed that potassium feldspar could be decomposed by sulfuric acid but only about 12% dissolution rate of potassium under atmospheric pressure which means with only sulfuric acid and potassium feldspar in the atmospheric pressure reaction system,high dissolution rate of potassium c... |
