Canada’s only copper smelter in Rouyn-Noranda, Quebec is proposing a new approach to meet environmental targets. The Horne Smelter, part of Glencore Canada, processes 210,000 tonnes of copper and precious metals annually.
A 2022 study by Quebec’s public health body revealed the smelter exposed Rouyn-Noranda to harmful arsenic and cadmium levels for decades. The Quebec government required the company to reduce emissions substantially, though without a defined timeline. Glencore and provincial authorities have been negotiating over the years on emissions controls, although the company has reported steady progress.
