摘要(Abstract)：

锂作为新能源电池等领域应用广泛，战略价值重大。我国锂资源以卤水型为主，提取难度大、开发条件差，亟须新型锂资源，煤系锂资源的发现为此提供了新方向。煤中锂主要赋存于高岭石等黏土矿物，煤灰中锂赋存在玻璃相。研究其赋存状态的方法包括逐级化学提取、数理统计分析等间接法，以及TOF-SIMS、LA-ICP-MS等直接法。煤系锂提取以酸浸为主，因矿物耐酸性常需预处理，预活化-酸浸法（机械、焙烧活化）可提升浸出率，有机酸（如草酸）浸出为绿色提锂提供思路。分离提纯多采用溶剂萃取、沉淀、吸附法，但煤基体系应用研究较少。目前，煤系锂提取面临强酸污染、能耗高、分离技术适应性差等问题。未来需深入研究绿色提取技术、优化工艺降能耗，实现高效环保利用。
