Scandium (Sc) has unique properties and is one of the most valuable elements in the periodic table. Scandium can be used in solid oxide fuel cells and to form high strength aluminum alloys of value for e.g. the aerospace industry. Scandium is often grouped together with the rare earth elements (REE). Scandium can be found in bauxite residues, so called red mud. It is possible to extract and enrich scandium from red mud by leaching and solvent extraction. Scandium can then be recovered from the pregnant strip liquor by crystallization. The strip liquor will however still contain certain impurity elements. In the present work a method for obtaining a pure scandium solid phase by direct crystallization from the strip liquor is presented. The impurity incorporation has been studied by performing seeded crystallization experiments under controlled conditions.
