Glencore accused of discharging copper concentrate dust at Horne smelter

ROUYN-NORANDA, QUEBEC, AUG 1 – Glencore's Horne smelter allegedly released copper dust due to dry conditions, prompting a cleanup costing hundreds of thousands and potential fines starting at $30,000.

  • In March 2023, Glencore's Horne smelter in Rouyn-Noranda, Quebec, was charged under provincial environmental regulations for the suspected emission of copper concentrate dust into the atmosphere.
  • The charges came after locals posted images online showing an unusual layer of dark snow covering the area.
  • The company inspected the site, conducted a cleanup costing several hundred thousand dollars, and added a dome to store concentrate to reduce dust leaks.
  • Glencore could face a minimum fine of $30,000, while Quebec's Environment Ministry warned the contaminants are likely harmful to humans.
  • The event led to public health advisories, land decontamination orders, and required Glencore to improve practices to prevent future contamination.
