Symposium Scandium Extraction and Use in Aluminum Alloys
Presentation Title State of the Art Technologies for Scandium Recovery, Purification, and Aluminum-Scandium Alloy Production

Abstract Scope Aluminum-based alloys containing minimal amount of scandium have been extensively investigated for their exceptional mechanical properties which make them particularly suitable for advanced engineering applications such as aerospace and defense by allowing design and construction of high-strength, lightweight structural parts. Understanding the challenges in scandium sourcing, recovery and purification processes, and alloying methods, a vertically integrated solution has been developed which includes a portfolio of technologies: (i) patented recovery of Sc from Sc-containing ores and industrial waste streams from ppm levels to 20-25 % in the concentrate – validated in the pilot scale; (ii) purification of Sc from concentrates containing impurities such as titanium, iron and other rare earths to produce >99.5 % pure scandium oxide – validated in the commercial scale; and (iii) patent-pending technology for production of the final alloy through a one-step alloying process using a vacuum induction furnace, refined casting technique, and suitable heat treatment processes – validated at demonstration scale.
