| Abstract: |
| Applying calcium chloride as additive, sodium-potassium aluminosilicate was replaced with calcium in a certain condition to form water-soluble alkali metal chloride. Single factor test of roasting was investigated. Recovery rate of Rb2O is 98% above under the optimum pyrolysis conditions including roasting at 950 ℃ for 1.5 h, and addition of calcium chloride of twice weight of mineral. |
