Rio Tinto to sell scandium oxide to US agency for defense stockpile

The U.S. Defense Logistics Agency wants to purchase scandium oxide from Rio Tinto for up to $40,000,000 over the next five-year period to ensure supplies of this critical material to add to the nation's stockpile.

Scandium, one of the rare-earth elements, has gained prominence in recent years, especially since China, its main producer, began imposing export controls.

"Scandium was, up until recently, mainly sourced from China. China implemented export controls for scandium in late 2024. This constrained the supply and led to this acquisition by the National Defense Stockpile," DLA stated in a report published last week.

The company plans to purchase 6.4 tons of scandium dioxide within the next five years.

The first year, it will seek almost 2 tons of scandium oxide. This is equivalent to 5% of the global production last year, which was 40 tons.

In August, the U.S. gave up to $10,000,000 to Elk Creek Resources (a unit of NioCorp) to increase the domestic supply of scandium.

Currently, the U.S. Government must import the product used in many defense systems from abroad.

The document stated that "Rio Tinto Services Inc. is the only vendor capable of meeting the government's product requirements at the required capacity for the contract."

Rio Tinto stated that it would not comment commercially, but said it was "actively working with the U.S. Government to identify opportunities and leverage the available support in order to increase domestic production for the American Market and strengthen supply chain."

Rio Tinto scientists developed the first process in 2020 that allows high-purity scandium dioxide to be extracted from waste streams produced during titanium dioxide production without any additional mining.

Rio Tinto responded to an email asking for comments by saying that it was "uniquely positioned" to secure materials vital to America's future.

Rio Tinto's Quebec facility, Canada, produced its first batch of scandium dioxide three years ago. It currently has a production capacity of about 3 tons per year. (Reporting and editing by Ros Russell; Polina Devlin)
