摘　　要：在全球能源结构转型与新能源汽车产业快速发展的背景下,锂资源作为战略性关键矿产的战略地位日益凸显。作为我国盐湖锂资源核心区的青海省,其盐湖卤水型锂资源开发已成为保障锂资源供给安全的关键路径。青海盐湖卤水普遍存在镁锂比高、杂质干扰严重等特性,以察尔汗、东台吉乃尔等典型盐湖为代表,提锂过程面临分离效率低、能耗高等共性难题。文章聚焦青海盐湖提锂过程中杂质离子分离与控制技术体系,通过解析区域卤水资源特性、本土化分离技术原理及过程控制机制,系统探讨多技术耦合的创新路径。研究将结合青海蓝科锂业、中信国安等省内龙头企业的工业化实践案例,揭示杂质分离技术的演进规律与优化方向,为构建青海特色盐湖提锂技术体系提供理论支撑,对推动青海锂电产业高质量发展具有重要工程价值。Against the backdrop of global energy structure transformation and rapid development of the new energy vehicle industry,the strategic position of lithium resources as a strategic key mineral is increasingly prominent.As the core area of lithium resources in salt lakes in China,Qinghai Province's development of brine type lithium resources in salt lakes has become a key path to ensure the safety of lithium resource supply.The brine of Qinghai salt lakes generally has characteristics such as high magnesium lithium ratio and severe impurity interference.Represented by typical salt lakes such as Cha'erhan and Dongtai Jinnaer,the lithium extraction process faces common challenges such as low separation efficiency and high energy consumption.The article focuses on the impurity ion separation and control technology system in the lithium extraction process of Qinghai salt lake.By analyzing the characteristics of regional brine resources,the principle of localized separation technology,and the process control mechanism,the innovative path of multi technology coupling is systematically explored.The research will combine the industrial practice cases of leading enterprises in Qinghai such as Lanke Lithium Industry and CITIC Guo’an to reveal the evolution law and optimization direction of impurity separation technology,providing theoretical support for the construction of a lithium extraction technology system with Qinghai's characteristic salt lakes,and having important engineering value for promoting the high-quality development of Qinghai's lithium battery industry.
