| 摘 要： | 在实验室建立了一套溶浸试验装置。以水为浸出剂，通过测定60℃、90℃、100℃时浸出液中KCl、NaCl、MgCl：组成浓度随时间的变化，考察老挝万象钾镁盐矿在水中的溶解行为，得到60℃、90℃、100℃条件下钾镁盐矿中KCl在水中的平衡浓度（质量百分含量）分别为5．73％、6．90％、7．93％。浸出液中KCl平衡浓度随温度的升高而增大。试验结果对老挝万象钾镁盐矿资源的开发利用具有理论参考和实际应用价值。

| Abstract: | Based on leaching - process, an apparatus of leaching - experiment for K - Mg Salt - deposit in Vientiane Plain was constructed. When water was used as the leaching agent, the equilibrium liquid concentration of K - Mg Salt - deposit in Vientiane Plain were KCl, NaCl, MgCl2 under 60℃, 90℃, and 100℃. The concentration of KCI in 60℃, 90℃, 100℃ were 5.73%, 6.90%, 7.93%, respectively. It was showed that the equilibrium liquid concentration of KC1 in leaching liquor increased with increasing temperature. The laboratory result showed the possibility for extracting potassium from K- Mg Salt -deposit in Vientiane Plain underground by leaching. |
