Rio Tinto has initiated a new ore sorting demonstration project at its Lac Tio mine in Havre-Saint-Pierre. This innovative project is part of the company’s broader strategy to enhance efficiency and sustainability in its operations.
The ore sorting technology aims to improve the processing of mineral resources by increasing the quality of ore that advances to the next stage. By implementing this technology, Rio Tinto seeks to reduce waste, lower energy consumption, and decrease costs, which are crucial steps toward achieving more sustainable mining practices.
The project at the Lac Tio mine will assess the effectiveness of advanced ore sorting systems. These systems sort ore based on titanium and scandium content, a process that traditionally requires significant time and resources. The new technology is designed to streamline this operation by precisely separating commercially exploitable rock from waste rock before further processing.
A key benefit of this initiative is the reduction in the amount of waste material processed, which in turn reduces the environmental impact of mining activities. Less waste means less energy is required for subsequent processing stages, which contributes to lower greenhouse gas emissions.
This demonstration project is not only a technological advancement but also a strategic move by Rio Tinto to strengthen its position in the mining industry. By embracing cutting-edge technologies, the company is poised to set new standards in resource efficiency and environmental responsibility.
“The use of ore sorting technology represents a tangible opportunity to optimise our processes right from the extraction stage, allowing us to maximise value from our resources, while reducing the emissions associated with transporting and processing ore. The support from the Government of Quebec highlights the key role that Rio Tinto plays in the critical and strategic minerals production essential to the energy transition. It’s also a unifying project for our employees, the community of Havre-Saint-Pierre and the community of Ekuanitshit, with whom we share a desire to evolve our practices in a responsible manner.”

The outcome of the project will provide valuable insights into the potential applications of ore sorting technology. If successful, it could reshape the future of mineral processing, offering a model for other mining enterprises seeking to implement more sustainable practices.
The 2025 activities will include engineering, commissioning of the ore sorting circuit, and technological validation. Additional equipment will be integrated in 2026 to automate the process and produce batches of enriched ore.
In addition to the environmental and cost benefits, the project underscores Rio Tinto’s commitment to innovation in mining. By investing in technology that reduces waste and energy use, the company is taking significant steps toward achieving its long-term sustainability goals. Such advancements are essential for meeting future demands while minimizing the ecological footprint of mining operations.
