我国盐湖卤水以硫酸镁亚型为主，具有较高的镁锂比值。从中国盐湖卤水中开采锂一直是一个长达数十年的技术挑战。简要讨论了各种技术的优缺点。化学萃取法是我国高镁锂比盐湖卤水中回收锂的最重要技术。其他几项创新技术，包括锂离子筛、膜分离和电渗析，也成为潜在的选择。
Chinese salt-lake brine is mainly of the magnesium sulfate subtype with a high Mg/Li ratio. Mining lithium from Chinese salt-lake brine has been a decades-long technical challenge. The pros and cons of various technologies are briefly discussed. Chemical extraction has been the most important technology for the recovery of lithium from Chinese salt-lake brine with a high Mg/Li ratio. Several other innovative technologies, including lithium ion sieves, membrane separation, and electro-electrodialysis, have also emerged as potential options.
