Salt Lake Lithium Extraction: Lanran Expands a 20,000 t/y Lithium Hydroxide Project with an Additional Electrodialysis System
As global demand for battery-grade lithium hydroxide continues to rise, improving the efficiency of salt lake lithium extraction has become a key focus for the lithium industry. Advanced electrodialysis (ED) technology enables lithium producers to concentrate lithium-rich brine more efficiently while supporting stable, large-scale production.
Lanran has completed the commissioning of an additional homogeneous membrane electrodialysis system for a 20,000 t/year lithium hydroxide project at the Lago Co Salt Lake in Xizang, China. The newly installed ED unit expands the plant’s lithium brine concentration capacity and is now operating steadily as part of the overall production process.
Project Highlights
- Application: Salt Lake Lithium Extraction
- End Product: Battery-Grade Lithium Hydroxide Monohydrate
- Production Capacity: 20,000 t/year
Why Electrodialysis Is Important for Salt Lake Lithium Extraction
In modern salt lake lithium extraction plants, electrodialysis plays an important role in upgrading lithium-rich brine before downstream purification and lithium conversion. Compared with conventional concentration methods, electrodialysis offers several advantages:
- Efficient concentration of lithium-rich brine
- Lower energy consumption than thermal concentration processes
- Stable continuous operation for industrial production
- Reduced chemical consumption in downstream processing
- Easy integration with membrane separation and bipolar membrane electrodialysis (BPED) systems
These benefits help improve production efficiency while supporting more sustainable lithium manufacturing.
