Method for recovering scandium |
| abstract |
The present invention effectively recover high-grade scandium from nickel oxide ores. The present invention includes a leaching step (S 1 ) for charging nickel oxide ores and sulfuric acid into a pressurized vessel, a neutralizing step (S 2 ) for adding a neutralizing agent to the leachate to obtain a neutralized precipitate and a neutralized liquid, a sulfidizing step (S 3 ) for adding a sulfidizing agent to the neutralized liquid, an ion exchange step (S 4 ) for bringing the sulfidized solution into contact with a chelate resin, a solvent extraction step (S 6 ) for bringing a Sc eluent into contact with an extracting agent, a Sc precipitation Step (S 7 ) for adding a neutralizing agent or oxalic acid to a stripping solution, and a calcination step (S 8 ) for drying and calcining a precipitate to obtain scandium oxide. |
