Case Study: Zangge Lithium's Boron Removal Electrodialysis System

【Project Overview】

Traditional salt lake lithium extraction processes often face bottlenecks such as lengthy flowsheets, difficulty in impurity separation, and low recovery rates. These challenges are particularly pronounced in salt lakes with complex compositions high in calcium, magnesium, and boron, making cost-effective extraction difficult. Leveraging its independently developed core electrodialysis technology, Create innovatively constructed an integrated process coupling "Adsorption + Membrane Filtration + Electrodialysis." This achieved comprehensive optimization across the entire production chain, from pretreatment to deep concentration. The system not only enables highly efficient impurity removal and deep concentration of lithium ions but also achieves top-tier international performance in multiple key metrics, setting a new benchmark for the high-quality development of China's salt lake lithium industry.

【Project Highlights】

Dramatically Improved Resource Extraction Efficiency
Lithium recovery rate exceeds 99%, significantly surpassing the approximately 80% level typical of conventional processes and drastically reducing resource waste.
Product Purity Meets High Standard
The purified lithium solution post deep impurity removal can be directly used for producing battery-grade lithium carbonate and lithium hydroxide, breaking through the historical limitation of constrained product quality from salt lake extraction.
Significantly Reduced Overall Costs
The short process and low-energy consumption design markedly decrease both capital and operating expenses per unit output, enhancing our company's market competitiveness.
Green Process Enables Sustainable Development
The system generates no secondary pollution and minimizes wastewater discharge, achieving a harmony of economic benefit and environmental performance.
