LONDON—Glencore is planning to close its Horne smelter, Canada’s largest copper metal-producing operation, due to environmental issues and the millions of dollars needed to upgrade the facility, two sources with knowledge of the matter said.
The London-listed miner does not disclose copper metal production figures for its Canadian operation, but industry sources estimate annual output at more than 300,000 metric tons.
