| 摘要: |
| 藏北高原恶劣的自然地理条件使扎仓茶卡珍贵的锂资源的开发极为困难,必须采用尽可能简化的提取工艺才能降低成本。本文提出一种经CaO、(NH4)2C2O4和Na2CO3三步沉淀得到粗Li2CO3的简化工艺,其产品纯度可达85.62%,总回收率约20%,卤旦回收率约为76%。 |

| Abstract: |
| In Qingzjmg Plateau, Li is very difficult to be exploited and utilized because of its natural and geographic conditions. A simplified three-stage-precipitation technique, by using CaO, (NH4)2C2O4 and Na2CO3 for extracting crude Li2CO3 was put forward. The results show that its purity may reach 85.62%, the rate of retrieval about 20% from salt lake and 76% from the concentrated brine. |
