Lithium Extraction from Aluminum Slag

【Project Overview】

Amidst the dual challenges of sustained global lithium demand and the green transition of extraction technologies, conventional lithium recovery processes face bottlenecks such as limited recovery rates, high energy consumption, and significant environmental impact. Create's innovatively developed multi-stage electrodialysis integrated concentration process, through a comprehensive technological redesign, achieves a leap from "resource consumption" to "resource circulation," providing a novel solution for the industry's green transformation.

As the comprehensive process designer for this project, Create has established a complete green industry chain, spanning from pretreatment to the final battery-grade product. This has not only significantly improved lithium resource recovery rates but also pioneered a new paradigm for green, low-carbon extraction.

【Project Highlights】

Breakthrough Core Technology Solving Industry Bottlenecks
The project employs Create's independently developed multi-stage electrodialysis integrated concentration process, directly addressing the three core pain points of traditional lithium extraction – "low recovery rate, high energy consumption, and heavy pollution." It represents a fundamental upgrade of the technical pathway, offering a new solution for high-efficiency, low-energy lithium resource recovery.
Record-High Lithium Recovery Rate, Maximizing Resource Utilization
Leveraging an efficient process design, the project achieves a groundbreaking industry benchmark of over 98% lithium recovery rate. This drastically improves the extraction efficiency of scarce lithium resources, achieves "complete utilization," and significantly reduces raw material costs per unit product.
Fully Integrated Proprietary Design Ensures Precision Control & Optimal Energy Efficiency
Green Circular Closed Loop, A Win-Win for Environment & Economics
The project successfully implements the reuse of electrolyte mother liquor and achieves near-zero liquid discharge for wastewater. This not only completely resolves environmental compliance pressure but also substantially reduces the consumption of fresh chemicals and wastewater treatment costs through internal recycling, establishing a green production of "resources - product - renewable resources."
High-End Product Orientation, Extending the Value Chain
Innovatively adopting CO₂ anti-extraction technology for the deep recovery of lithium precipitation mother liquor, the process directly produces high-value-added battery-grade lithium carbonate. This transforms waste streams into premium products, extends the industrial value chain, and greatly enhances the project's overall economics.
