| Abstract: |
| Transformation technology to extract lithium from lepidolite by alkali dissolution was investigated. The results show that conversion rate of lepidolite is 98% above under the optimum conditions including concentration of sodium hydroxide solution of 50%, reaction temperature of 190 ℃, ratio of liquid to solid of 3.5∶1, and reaction time of 4 h. |
