Rio Tinto Launches $1.5B Low-Carbon Aluminum Expansion in Quebec

Published: Jun 1, 2026 10:12
Rio Tinto announced that it had officially commenced commissioning of its $1.5 billion low-carbon aluminum smelter expansion project located in Quebec, Canada. The mining giant expected that the project would be fully operational by the end of this year, with all 96 new electrolysis pots at Complexe Arvida up and running by then. Upon completion, the smelter's annual primary aluminum capacity would increase by approximately 160,000 mt, and total aluminum production using low-carbon AP60 smelting technology would reach 220,000 mt. The AP60 expansion project would provide strong support for ELYSIS — a joint venture co-founded by Rio Tinto and Alcoa — in its transition toward carbon-free aluminum electrolysis technology.
