Rio Tinto said it plans to invest over $1 billion in its Canadian aluminium smelters to improve production efficiency through modernization and expansion.
The Anglo-Australian mining giant, which acquired the assets through its purchase of Alcan in 2007, said it will invest about $760 million on completing the first phase of its AP60 plant in Saguenay-Lac-Saint-Jean, Quebec.
