NOVELTY - Nickel oxide ore and sulfuric acid are inserted in a pressurized container and separated (S1) into leachate and leach residue. Neutralizing agent is added (S2) to leachate to obtain post-neutralization liquid which is sulfurized (S3) and separated into nickel sulfide and post-sulfurization liquid. The liquid is contacted (S4) with chelate resin, to adsorb scandium and to obtain scandium eluting solvent. The obtained solvent is extracted (S6). Back-extraction agent is added to extraction liquid to obtain back-extraction material which is baked (S8) to collect scandium.    USE - Collection of scandium used as additive of high strength alloy and electrode material of fuel cell.    ADVANTAGE - The method enables efficient recovery of scandium of high quality from nickel oxide ore.    DETAILED DESCRIPTION - Nickel oxide ore containing scandium, aluminum and chromium and sulfuric acid are inserted into a pressurized container under high temperature and pressure, and separated into solid and liquid to obtain leachate and leach residue. A neutralizing agent is added to the leachate to obtain neutralization precipitate and post-neutralization liquid. A sulfurizing agent is added to the liquid after neutralization, and separated into nickel sulfide and post-sulfurization liquid. The liquid is contacted with a chelate resin, to adsorb scandium to the chelate resin, and to obtain a scandium eluting solvent. The scandium eluting solvent is contacted with an extractant, and a back-extraction agent is added to extraction liquid to obtain back-extraction material. The obtained back-extraction material is baked to obtain scandium oxide, and thus collection of scandium is enabled.
