| titleOfInvention | Method for recovering scandium |
| abstract | The present invention effectively recovers high-grade scandium from nickel oxide ores. The present invention includes a leaching step (S1) for charging nickel oxide ores and sulfuric acid into a pressurized container to cause solid-liquid separation of a leachate and a leaching residue under high temperature and high pressure, a neutralizing step (S2) for adding a neutralizing agent to the leachate to obtain a neutralized precipitate and a neutralized liquid, a sulfidizing step (S3) for adding a sulfidizing agent to the neutralized liquid to separate a nickel sulfide and a sulfidized liquid, an ion exchange step (S4) for bringing the sulfidized solution into contact with a chelate resin to adsorb Sc onto the chelate resin to obtain a Sc eluent, a solvent extraction step (S6) for bringing the Sc eluent into contact with an extracting agent to obtain a back-extraction liquid, a Sc precipitation step (S7) for adding a neutralizing agent or oxalic acid to the back-extraction liquid to obtain a precipitate, and a calcination step (S8) for drying and calcining the precipitate to obtain scandium oxide. |
