Sudbury, Ontario has been home to Glencore’s Sudbury Integrated Nickel Operations (Sudbury INO) since 1928.

These operations include exploration, two underground mines (Fraser and Nickel Rim South), Strathcona Mill and the Sudbury Smelter, which are all located in the Sudbury basin. The Strathcona Mill receives ore from the two mines as well as third-party custom feed ores. The Sudbury Smelter processes the nickel-copper concentrate as well as custom feed materials to produce a nickel matte, which is sent to port facilities in Quebec City, and from there to Glencore’s Nikkelverk refinery in Norway.
