Invention Reference Number
The growing reliance on rare earth elements (REEs) in advanced technologies, combined with global supply chain challenges, has created a critical need for domestic sources. This invention introduces a novel, energy-efficient method for producing high-purity REEs from mining tailings. The process offers a scalable, cost-effective approach that reduces waste and strengthens domestic supply resilience.
Description
This technology presents a new process for separating and purifying rare earth elements (REEs) from mining tailing materials. By combining selective dissolution with advanced membrane-based separation, the method enables efficient extraction of high-purity REEs from complex feedstocks. The process is designed to minimize energy consumption and material waste while maintaining scalability for industrial applications. Unlike conventional techniques that rely heavily on chemical reagents or intensive processing steps, this approach leverages a more controlled separation mechanism adaptable to a range of mining-derived materials. The result is a streamlined and cost-effective route for domestic REE production, supporting critical manufacturing sectors dependent on these materials.
