Rio Tinto to Test Titanium and Scandium Sorting Technology

Rio Tinto Titanium Mining

Rio Tinto Invests in Ore-Sorting Innovation

UK-Australian mining firm Rio Tinto will invest C$7.6mn ($5.6mn) to test a new ore-sorting technology at its Lac Tio mine in Quebec, Canada. The technology will sort ore based on titanium and scandium content directly at the source, reducing the amount of material transported to Rio Tinto’s iron and titanium metallurgical and critical minerals complex in Quebec.

The government of Quebec will contribute C$2.5mn ($1.8mn) through its support program for critical and strategic metals processing. This partnership underscores the region’s focus on developing advanced processing capacity for critical minerals.

Importance of Titanium and Scandium in Global Markets

Rio Tinto’s Quebec operations already produce titanium dioxide, covering 19% of global demand, alongside scandium oxide. Titanium dioxide is widely used in pigments and sunscreens, while scandium oxide plays a vital role in high-strength aluminum alloys for aircraft, as well as in electronic ceramics and glass.

As a result, the new sorting technology has the potential to increase efficiency, reduce carbon intensity, and strengthen North America’s position in critical minerals supply chains. By advancing titanium and scandium processing, Rio Tinto could also enhance the security of supply for industries facing rising demand.

The Metalnomist Commentary

Rio Tinto’s investment in titanium and scandium ore-sorting technology signals a clear shift toward greater efficiency and sustainability in critical minerals. By reducing transport needs and improving resource utilization, the project strengthens Quebec’s role as a global hub for strategic materials. This initiative also highlights the increasing importance of scandium, a rare but essential element for advanced manufacturing.
