Rio Tinto has successfully started commissioning its US$1.5 billion AP60 smelter expansion at Complexe Arvida in Quebec, marking a major milestone for the deployment of its state-of-the-art, low-carbon aluminium smelting technology.

The start-up, which began in March, is expected to be completed by the end of 2026 with all 96 new pots operating. This will increase the plant's production capacity by approximately 160,000 metric tonnes of primary aluminium annually for a total of 220,000 metric tonnes produced with the AP60 technology.

The AP60 expansion, together with the planned aluminium recycling centre at Arvida, will more than offset the loss of production associated with the closure of the older Arvida potrooms, which is expected to be completed in June.

The expansion will directly support approximately 100 permanent high-quality jobs locally and help consolidate positions across the supply chain. During its peak construction period, more than 1,500 jobs were created and the project generated more than $1 billion in economic benefits for the province of Quebec through spending with contractors and suppliers.

Representing the next chapter of Rio Tinto's century-long history in Quebec, it strengthens its ability to supply customers in North America with low-carbon, high-quality aluminium for transportation, construction, electrical applications and consumer goods.

Developed by Rio Tinto's Research and Development teams, the AP60 technology is among the most efficient and lowest carbon technology currently available, at commercial scale. When combined with the hydropower used at Rio Tinto's operations in Canada, it generates one-sixth of the greenhouse gas emissions per tonne of aluminium, when compared with the industry average, and half the emissions of the technology currently used at the adjacent older Arvida smelter1. It will deliver significant improvements, including an expected reduction of up to 90% in fine particulate matter.

The AP60 expansion supports the transition to carbon-free aluminium electrolysis technology being developed by ELYSIS in Saguenay–Lac-Saint-Jean, Québec, a partnership that includes Rio Tinto. Supported by the Government of Canada, through the Strategic Innovation Fund, a demonstration plant is being built in Quebec in partnership with the Government of Quebec, through Investissement Quebec, to advance this breakthrough technology, which eliminates all direct greenhouse gas emissions from aluminium smelting and produces oxygen as a by-product.

Rio Tinto Aluminium & Lithium Chief Executive Jérôme Pécresse said: "For 100 years, Quebec has been at the heart of the aluminium industry, and with AP60, Rio Tinto is now strongly positioned for decades to come with one of the most advanced smelting technologies operating at commercial scale. This milestone brings into production the first major primary aluminium project in the West in more than a decade and demonstrates Rio Tinto's ability to deliver world-class, low-carbon technologies.
