Lithium Concentration
Concentration to reduce MVR cost LiOH, LiCl, Li₂SO₄, LiNO₃ concentration
Description
Lanran Tech applies conventional Electrodialysis (ED) to pre-concentrate lithium from salt lake brines or lithium ore leachates. The process efficiently removes water and partial impurities, significantly increasing lithium ion concentration. This provides a cleaner, more energy-efficient feed solution for downstream lithium product preparation.
Process
- Pretreated brine or leachate enters the ED system.
- Under a DC electric field, lithium ions and selected salts migrate through ion-exchange membranes into the concentrate chamber.
- The result: a lithium-rich concentrate and a low-lithium diluate.
Applications
- Salt lake brine lithium extraction
- Pre-concentration of leachates from spodumene and mica
Key Advantages
High efficiency & energy saving – Compared with evaporation, ED reduces overall concentration costs.
Selective ion concentration – Enhances the efficiency of downstream lithium recovery.
Modular & adaptable – Flexible system design for diverse brine conditions.
