ArcelorMittal Mines Canada operates the country's largest open-pit iron ore mine and is Canada's first iron ore producer in the country. This is complemented by ArcelorMittal Infrastructure Canada (AMIC), which manages rail and port facilities at Port-Cartier for global shipments.
In 2025 we celebrated 20 years of mining leadership in Liberia. Our Phase II expansion to quadruple production to 20 million tonnes, modernise rail and port infrastructure and open new growth opportunities, is nearing completion.
In Brazil, Serra Azul sits in the heart of the Quadrilátero Ferrífero region, one of the world’s richest iron ore belts, reinforcing our position as a trusted supplier to global markets.
Mining is a cornerstone of our business, and we have big ambitions for its future. We take our responsibility seriously, doing things the right way to earn trust in our products and processes, while creating long-term value for our business and the communities where we work.
Our seaborne iron mines in Canada, Liberia and Brazil produce a range of high-quality products, including iron ore lump, fines, concentrate, pellets and sinter feed.
We are active across the full value chain – from exploration and development to mining, concentration, pelletising, rail transport and port operations.
We are deeply committed to mining responsibly and sustainably. Partnering closely with local communities, we build skills, create opportunities and support infrastructure for lasting development.
Sustainability within ArcelorMittal's mining segment is fundamental to securing long-term operational resilience, maintaining regulatory compliance, reducing ecological impact and preserving its social license to operate. Through continuous monitoring, transparent reporting, close collaboration with Global R&D, and the adoption of advanced technologies, ArcelorMittal enhances performance across its mining activities while reinforcing the company's commitment to a more sustainable and responsible global mining sector.
ArcelorMittal’s Liberia Phase II project is poised to transform both the group and the region, while quadrupling production to 20 million tonnes,
The project includes a modern concentrator plant and upgrades to rail and port infrastructure, while Phase II operations continue alongside construction in Direct Shipping Ore mode.
The Phase II implementation is progressing well, with significant headways made across engineering, procurement, controls, and construction.
