Our operations

Our operations

+ Aluminium


Alma (Alma, Quebec)
The Alma smelter is recognised as one of the aluminium industry’s environmental leaders.

Alouette (Sept-Iles, Quebec)
Alouette is the largest smelter in the Americas and one of the world's most efficient. Rio Tinto has a 40 per cent stake in the independent company that owns and operates Alouette.

Arvida (Saguenay, Quebec)
The Arvida smelter began operations in 1954. The aluminum produced at the Arvida smelter is cast into shapes that create value for customers, mainly in the automotive sector in the United States.

Arvida Aluminum Smelter, AP60 Technology Centre (Saguenay, Quebec)
The Centre helped pioneer AP60, which is the world’s most technologically advanced aluminium smelting technology. It uses energy more efficiently and is 40 per cent more productive than previous generations of AP technology.

Bécancour (Quebec)
Rio Tinto owns 25.1 per cent of the Bécancour smelter, which is operated by Alcoa. Bécancour was the first Quebec company to become an elite member of Hydro-Québec’s Écolectrique network.

Grande-Baie (Saguenay, Quebec)
The Grande-Baie smelter produces aluminum that is cast into many shapes, destined for specialized applications around the world. The smelter is recognised as a leader in innovation, and health and safety across the global aluminum industry.

Laterrière (Saguenay, Quebec)
Designed with industry-leading technology, Laterrière produces 244,000 tonnes of sheet ingot and hot metal every year.

Kitimat (British Columbia)
Kitimat is one of the largest manufacturing complexes in British Columbia. The new smelter produces half the emissions of its predecessor and is one of the most efficient, greenest and lowest-cost smelters in the world.


Vaudreuil (Saguenay, Quebec)
Vaudreuil transforms bauxite to alumina, supplies the majority of our smelters in the region, and is one of the world’s cleanest, most energy-efficient refineries.

Hydroelectric plants

Chute-à-Caron (Saguenay River, Quebec)
We invested ten years and US$75 million to restore this hydroelectric plant, which opened in 1931 and can produce 222 megawatts of renewable energy.

Chute-à-la-Savane (Peribonka River, Quebec)
Opening in 1953, Chute-à-la-Savane was one of Canada’s first partially uncovered hydroelectric plants.

Chute-des-Passes (Peribonka River, Quebec)
Chute-des-Passes is an underground hydroelectric plant that can generate 833 megawatts of clean, water-driven energy.

Chute-du-Diable (Peribonka River, Quebec)
Like Chute-à-la-Savane, this 224-megawatt plant was one of the first partially uncovered hydroelectric plants in Canada.

Shipshaw (Saguenay River, Quebec)
Shipshaw plays a vital role in our hydroelectric power network. In 2012 we installed a 13th turbine at Shipshaw, which helps us use the water resource more efficiently, delivering more clean, renewable energy to our operations in Quebec.

Isle-Maligne (Saguenay River, Quebec)
Isle-Maligne was built in 1926 and was the first of Rio Tinto’s six power stations in the Saguenay-Lac-Saint-Jean region of Quebec.

Kemano Power House (Kemano, British Columbia)
The Kemano hydroelectric plant helps power our Kitimat smelter and provides electricity to nearby communities.

+ Iron Ore

Mining operations

Rio Tinto Iron Ore Company (Labrador City, Newfoundland and Labrador)
Our iron ore operation includes a mine, a concentrator, and a plant that produces iron ore pellets – the raw material used to make steel. Our 418-kilometre railway links the plant to our port in Sept-Îles.


Sept-Îles (Quebec)
The Sept-Îles port can stockpile five million tonnes of iron ore pellets and concentrate and links us to fast-growing markets in the Pacific Rim.

+ Diamonds

Diavik Diamond Mine (Lac de Gras, Northwest Territories)
Every year, Diavik produces some 6 to 7 million carats of large, white, gem-quality diamonds from the richest deposit of diamonds ever found in Canada. In 2015, the mine discovered an 187.7-carat diamond, the Diavik Foxfire.

+ Ilmenite and titanium

Metallurgical complex (Sorel-Tracy, Quebec)
Rio Tinto Fer et Titane’s metallurgical complex is one of a kind. This network of interconnected plants produces raw materials for pigment manufactures, the automotive industry and foundries.

Havre St-Pierre Mine (Havre-Saint-Pierre, Quebec)
At Havre St-Pierre, we are mining the largest solid ilmenite deposit in the world
