| Abstract: |
| Lithium hydroxide is prepared from lithium-bearing waste by water leaching, and then transformed to lithium carbonate and lithium bicarbonate with carbon dioxide. One-step separation of boron and lithium is achieved. Lithium carbonate is produced from lithium bicarbonate solution by thermostatic decomposition. Orthogonal test is conducted to explore conditions to reach the highest yield and product purity. The results show that yield rate of lithium carbonate is 94% with purity of 90% above. |
