Scandium Supply Chain: From Mine to Market

Scandium has no primary mines; all production is as a byproduct of other metal processing. China accounts for ~66% of global output, recovered from rare earth, titanium, and iron ore processing. The Philippines (Sumitomo Metal Mining) and Russia are other sources. The entire global market is only ~25 tonnes/year. Primary applications are aluminum-scandium alloys (aerospace, sporting goods, 3D printing) and solid oxide fuel cell electrolytes. The extreme scarcity and high cost ($3,000-5,000/kg oxide) have prevented the formation of a liquid commodity market. Rio Tintos plan to recover scandium from titanium slag at its Quebec operations could be transformative, as it would leverage existing massive material throughput to produce scandium at potentially much lower cost than current sources.

Production Geography

Global Scandium production is led by China, which accounts for approximately 66% of world output, followed by Philippines. The full list of major producing nations includes China, Philippines, Russia, Australia. This geographic concentration means that disruptions in key producing regions can have outsized impacts on global supply and pricing.

Extraction Methods

Scandium is extracted using the following primary methods:

• Byproduct of uranium/titanium/nickel processing
• Recovery from red mud (alumina waste)

Processing and Intermediate Products

Scandium is primarily sourced from No primary scandium ores; recovered from uranium tailings, titanium slag, nickel laterite processing, and rare earth operations. After extraction, the raw material undergoes multiple processing steps including beneficiation, chemical treatment, and refining to reach the purity levels required by downstream industries. Typical ore grades range from Byproduct - 5-100 ppm in various ores.

Key Supply Chain Participants

The Scandium supply chain involves these major companies:

Supply Chain Vulnerabilities

Key vulnerabilities in the Scandium supply chain include concentration of 66% of production in China, limited processing capacity diversification, and long lead times for new mining projects. The high supply risk rating reflects the severity of these concentration risks and the difficulty of rapidly establishing alternative supply sources.
