Ruthenium Supply Chain: From Mine to Market

Ruthenium is produced exclusively as a byproduct of platinum and palladium mining, primarily in South Africa (~85%). The refining process involves distillation of volatile RuO4 during PGM processing. Total global production is ~35 tonnes/year. The dominant commercial application is in hard disk drive manufacturing, where nanometer-thick ruthenium layers enable high-density perpendicular magnetic recording. Ruthenium is also essential for chlor-alkali electrode coatings (DSA technology for chlorine production). Emerging interest in ruthenium as a lower-cost PEM electrolyzer anode catalyst (replacing expensive iridium) could transform the demand profile if technical durability challenges are solved.

Production Geography

Global Ruthenium production is led by South Africa, which accounts for approximately 85% of world output, followed by Russia. The full list of major producing nations includes South Africa, Russia, Zimbabwe, Canada. This geographic concentration means that disruptions in key producing regions can have outsized impacts on global supply and pricing.

Extraction Methods

Ruthenium is extracted using the following primary methods:

• Byproduct of platinum/palladium mining

Processing and Intermediate Products

Ruthenium is primarily sourced from Merensky Reef, UG2 Chromitite. 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 - ~0.3 g/t in PGM ores.

Key Supply Chain Participants

The Ruthenium supply chain involves these major companies:

Supply Chain Vulnerabilities

Key vulnerabilities in the Ruthenium supply chain include concentration of 85% of production in South Africa, 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.
