Scandium (Sc) has unique properties, highly valued for many applications. Future supply is expected to rely on unusually high-grade (up to 1000 ppm) lateritic Sc ores discovered in Eastern Australia. To understand the origin of such exceptional concentrations, we investi- gated Sc speciation in one of these deposits.

Moreover, a leachate solution obtained from a real rare-earth element ore was used to determine the performances of the proposed materials in a packed column configuration. The maximum Sc adsorption on the silica material surfaces is moderate (1 mg/g), but it is balanced by a great concentration factor (more than 100 times).

After the scandium precipitation and concentration, it was found that Sc can be re-leached and taken into the leach solution with 100 g/L of H 2 SO 4 acid with 0.2 solid to acid-water mixture at 60 °C within 60 minutes. As a future work, scandium may be recovered from the re-leach solution by solvent extraction or ion exchange method.
