Case Study: Electrodialysis System in Salt Lake Co., Ltd.'s 40,000-Ton Project

【Project Overview】

The development of China's salt lake lithium resources has long faced industry challenges including low extraction efficiency, significant impurity interference, and high overall costs. While traditional precipitation and adsorption methods can achieve basic lithium extraction, they struggle to balance high recovery rates with high product purity and exhibit clear shortcomings in co-removing impurities like boron and silicon. This has left many salt lake projects stuck in a development dilemma characterized by "failing to meet lithium production targets and lacking economic viability."

Create broke this deadlock through technological innovation. Centered on a core approach of "multi-impurity synergistic removal + efficient lithium resource enrichment," and integrating internationally advanced electrodialysis concentration processes, the company established a new paradigm for salt lake lithium extraction characterized by a short process, low energy consumption, and high purity. It delivered a comprehensive, full-chain technical solution for the national flagship project on comprehensive salt lake resource development, achieving systematic breakthroughs across the three critical dimensions of efficiency, purity, and energy consumption.

【Project Highlights】

• Recovery Efficiency: From "Resource Waste" to "Maximum Utilization"
  Traditional processes typically achieve lithium recovery rates below 75%, often requiring multiple cycles or additional investment for marginal improvement. Create's process enables lithium recovery rates to exceed 99.5%, truly achieving "complete utilization" of salt lake lithium resources and drastically reducing resource loss and external dependency.
• Product Purity: From "Repeated Purification" to "One-Step Achievement"
  The project achieved impurity removal rates of ≥87.03% for boron and ≥87.3% for silicon. The product meets battery-grade lithium standards without needing subsequent refining, significantly reducing purification costs while shortening the process.
• Energy Consumption & Operation: From "Labor-Dependent" to "Intelligently Optimized"
  Create provided one-stop technical support, from core equipment to operational optimization, establishing a highly efficient and stable lithium extraction operation. The system's energy consumption is significantly lower than the industry average, helping the project maintain leading economics throughout its lifecycle.
