Rusal Launches Scandium Oxide Pilot Plant to Boost Russia’s Rare Earth Capabilities

New Facility at Bogoslovsky Smelter to Produce Scandium from Red Mud, Potentially Expanding Global Supply by 75%

Rusal Sets Up Pilot Scandium Plant at Krasnoturinsk Smelter

Russian aluminium giant Rusal has announced the launch of a pilot scandium oxide facility at its Bogoslovsky aluminium smelter in Krasnoturinsk, Russia, aiming to produce 1.5 tonnes per year of scandium oxide. Given the global scandium output of just 20–25 t/yr, this project marks a major addition to global capacity.

Rusal plans to extract scandium from red mud, a waste by-product of alumina refining, using proprietary technology developed at its Krasnoyarsk Engineering and Technology Center. This contrasts with conventional scandium sources, which are typically by-products of titanium dioxide or uranium production.

If scaled to full commercial operation, the plant could eventually produce up to 19 t/yr of scandium oxide, placing Rusal among the world’s top producers of this high-value rare earth element.

Scandium Alloy Demand Rising Across Aerospace and 3D Printing Sectors

Scandium oxide is used to create aluminium-scandium alloys for ultra-lightweight structural components in ships, aircraft, railcars, and additive manufacturing (3D printing). These alloys enhance strength while reducing weight—making them highly desirable in aerospace and defense applications.

Rusal’s investment in the pilot project totals 500 million roubles ($5.73 million), with commissioning expected by year-end 2025. The project also aligns with broader geopolitical trends, including Russia’s renewed push to increase rare earth production. President Vladimir Putin has recently emphasized rare earths as a strategic priority for the country.

Russia Eyes Rare Earth Deals Despite Sanctions Landscape

On 25 February, Russia signaled its willingness to cooperate with the U.S. on developing rare earth assets, despite ongoing geopolitical tensions. This scandium oxide initiative positions Rusal—and Russia more broadly—as a significant player in non-Chinese rare earth supply chains, especially as nations look to diversify sources of strategic minerals.
