盐湖卤水提锂技术研究进展
Research progress on lithium extraction technology from salt lake brine
摘要
Abstract
With the rapid development of the global new energy industry,the demand for lithium is growing rapidly.The traditional hard rock lithium mining is faced with problems such as high cost and high environmental pressure.China is rich in salt lake resources.Lithium resources in salt lake brine account for 70％of the total lithium resources,and the development potential is huge.In this paper,the research status of lithium extraction technology from salt lake brine such as solvent extraction,adsorption,nanofiltration and electrodialysis is systematically reviewed.Solvent extraction can significantly improve the selectivity of lithium by optimizing the extractant and synergistic system.The efficient separation of lithium from high magnesium-lithium ratio brine by ion sieve material was realized by adsorption method.Membrane technology separates lithium through specific channels or electric fields,but its development is limited by the cost and stability of membrane materials.Future research needs to focus on material innovation,multi-process coupling and green low-carbon technology development to break through the bottleneck of lithium extraction from complex brines such as high magnesium-lithium ratio and low lithium concentration,promote the development of lithium extraction from salt lakes in the direction of high efficiency,intelligence and sustainability,and ensure the safety of lithium resource supply chain in China.关键词
