| Abstract: |
| The factors effecting lithium leaching rate from coal ash in sodium carbonate sintering process were investigated by orthogonal test with coal ash and sodium carbonate as raw materials. The results show that lithium leaching rate is 65% by alkaline process after roasted at 900 ℃ for 2 h with mass ratio of coal ash and sodium carbonate of 1︰1. |
