Scandium Oxides/Hydroxides TRIZ Cases
- High-Pressure Caustic Leaching for Scandium Recovery From Silicates
High-pressure caustic leaching breaks down silicate ore matrices before acid extraction, improving scandium and rare-earth recovery.
- Scandium Carbonate-Bicarbonate Leaching for Single-Stage Extraction
CO2-controlled carbonate-bicarbonate leaching replaces repeated cycles and costly sorbents with single-stage scandium precipitation.
- Scandium Oxide Sulfur Removal via Carbon-Mediated Heat Treatment
Carbon-mediated heat treatment removes sulfur impurities from scandium oxalate, addressing high sulfur content issues in fuel cell electrolyte applications.
- Scandium Separation from Complex Salt Mixtures
Sequential solvent extraction separates scandium from rare earth elements in complex salt mixtures, achieving 74.1% recovery.
