The global push for decarbonization and advanced manufacturing is accelerating demand for high-performance materials. Scandium, a key component in lightweight alloys and solid oxide fuel cells, faces supply chain vulnerabilities and high extraction costs. This creates a critical need for innovative, environmentally friendly extraction technologies that can secure supply and reduce costs, driving competitive advantage in aerospace, EV, and clean energy sectors.
Achieves High-Purity, Selective Extraction: Efficiently separates and extracts only scandium from impurities like rare earth metals and iron without clad formation.
Enables Significant Cost Reduction: Could reduce extraction costs by approximately ~65% compared to conventional methods through simplified processing and deep eutectic solvents.
Reduces Environmental Impact: Utilizes deep eutectic solvents, which are safer than traditional organic solvents, enabling a cleaner extraction process compliant with stricter environmental regulations.
This patent protects a specific deep eutectic solvent composition and method for selectively extracting scandium from solutions containing rare earth metals or iron. The claims were robustly defended against examiner rejections, resulting in a clear and strong patent with broad coverage and low invalidation risk.
This patent primarily covers scandium extraction using deep eutectic solvents. White space exists in applying similar solvent systems for other rare earth or critical mineral separations, or developing novel post-extraction purification methods.
Assuming an annual scandium refining volume of 10 tons, with conventional extraction costs at ~$150,000/ton (AI est.). This technology could reduce costs by approximately ~65% (a ~$100,000/ton reduction, AI est.), leading to an estimated annual cost saving of ~$1M (10 tons × ~$100,000/ton = ~$1M, AI est.).
