| titleOfInvention | Scandium recovery method |
| abstract | Efficient recovery of high-grade scandium from nickel oxide ore. The scandium recovery method of the present invention includes: loading nickel oxide ore and sulfuric acid into a pressurized container, and separating solid and liquid into leaching liquid and leaching residue under high temperature and high pressure (S1); adding a neutralizing agent into the leaching liquid to obtain Neutralization process (S2) of neutralizing deposit and liquid after neutralization; Vulcanizing agent is added in liquid after neutralization, is separated into the vulcanization process (S3) of liquid after nickel sulfide and vulcanization; Make chelating resin and vulcanization After the liquid contact, scandium is adsorbed on the chelating resin to obtain the ion exchange process (S4) of the scandium eluent; the extraction agent is contacted with the scandium eluent to obtain the solvent extraction process (S6) of the back extraction liquid; adding the neutralizing agent or oxalic acid into the stripping solution to obtain a scandium precipitation process (S7) of a precipitate; and a roasting process of drying and roasting the precipitate to obtain scandium oxide (S8). |
