Problem
Conventional lithium extraction relies on chemical-intensive hydrometallurgical processes that generate large volumes of hazardous waste and consume significant water and energy, limiting the sustainability of battery‑grade lithium supply chains.
Solution
Ellexco provides a chemical‑free direct lithium extraction (DLE) technology that isolates lithium ions directly from aqueous sources such as brine and geothermal fluids. The process uses proprietary physical‑separation mechanisms—such as selective adsorption and ion‑exchange membranes—to capture lithium without adding reagents, producing high‑purity lithium compounds suitable for battery manufacturing. By eliminating chemical reagents and reducing waste streams, the technology lowers environmental impact and operational costs. The modular system can be integrated into existing mining or geothermal operations, enabling on‑site lithium recovery and shortening supply chains. Real‑time monitoring and automated controls ensure consistent product quality and facilitate scale‑up to commercial throughput.
Target Audience
Primary customers are lithium producers, geothermal brine operators, and battery manufacturers seeking a low‑impact, on‑site lithium supply solution.
