Overview
Falconbridge Nickel Mines Limited was a Canadian mining and metals company established in 1928 by prospector and businessman Thayer Lindsley. It was created to develop nickel-copper claims in the Sudbury Basin of Ontario, an area that later became central to the economic development of northern Ontario. The company took its name from the Falconbridge township and settlement northeast of Sudbury; the community itself was named after Sir William Glenholme Falconbridge, an Ontario judge. From 1982 onward, the company traded as Falconbridge Limited. The deposits associated with Falconbridge had been identified earlier, including an ore-body discovery attributed to Thomas Edison in the early twentieth century, but commercial development awaited Lindsley's acquisition of the claims. Falconbridge built not only mines but also the infrastructure of a company town, including utilities, medical services and housing. By 1930 it was extracting underground ore and operating a smelter, followed by milling and sintering facilities in 1932. The company's early international expansion came in 1929 through the acquisition of Kristiansand Nikkelraffineringsverk in Norway. That transaction gave Falconbridge access to the Hybinette nickel-refining process and established a long-term refining presence at what became Falconbridge Nikkelverk in Kristiansand. During the 1950s and 1960s, Falconbridge expanded substantially in the Sudbury Basin, developing roughly a dozen additional mines and recovering nickel, copper and platinum-group materials. Its Norwegian refinery began recovering cobalt in 1952. In 1962, the acquisition of Ventures Limited added international operations and geological-exploration capabilities. Falconbridge subsequently broadened its geographic and commodity portfolio. Falcondo, its Dominican Republic nickel operation, began production in 1971. The company also developed or acquired assets in Canada, Latin America, the Caribbean, the United States, Norway and elsewhere, covering mining, smelting, refining, recycling and metal marketing. Technology and environmental management were important parts of the business. Falconbridge patented an internally developed chlorine-leach nickel-refining process in 1977. In the Sudbury region, it joined wider efforts to reduce sulfur-dioxide pollution through improved smelting and a sulfuric-acid plant. Capturing sulfur dioxide for conversion into saleable acid reduced atmospheric emissions while creating an additional commercial product. The original Falconbridge mine reached the end of its commercial reserves in the 1980s, but the company continued operating elsewhere in the Sudbury area and expanded through assets such as the Kidd Mine and Metallurgical Site in Timmins, Raglan in northern Quebec, Montcalm, and later projects and mines in Tanzania and South America. Falconbridge merged with Noranda in June 2005 after Noranda had proposed the combination earlier that year. The enlarged company inherited aluminum, recycling and additional base-metals operations, making it a diversified mining and processing group rather than a solely nickel-focused producer. In 2005, it reported revenue of US$6.9 billion, according to the cited Wikipedia account. The company then became the target of competing takeover proposals from Inco, Xstrata and other mining interests during a period of high base-metals prices. Xstrata, already a substantial shareholder, ultimately prevailed with a cash offer and absorbed Falconbridge in August 2006. Falconbridge's operations continued under the Xstrata Nickel identity, while the legal entity was renamed Xstrata Canada Corporation on 28 October 2007. Xstrata later became part of Glencore in 2013. Although the corporate brand disappeared, Falconbridge remains significant in Sudbury's industrial history. The company was for decades one of the region's largest employers and shaped the surrounding settlement, labor relations, infrastructure and environmental debates. The former company town was incorporated in 1957 and later became part of Greater Sudbury. Falconbridge Road and the preservation of the Edison Building as a civic archive reflect the continuing local legacy of the company. Although the corporate brand disappeared, Falconbridge remains significant in the industrial history of Sudbury. The company was one of the region's largest employers for decades and shaped surrounding settlements, labor relations, infrastructure and environmental debates.
History
Falconbridge began in 1928 when Thayer Lindsley acquired nickel-copper claims northeast of Sudbury and organized Falconbridge Nickel Mines Limited. The company developed a mine, smelter, mill and sintering plant and constructed a settlement to support employees. Its 1929 purchase of a Norwegian refinery brought the Hybinette nickel process and gave the company an international refining base. Expansion accelerated after the Second World War. Sudbury operations grew through new mines, while the Norwegian business added cobalt recovery. The 1962 purchase of Ventures Limited provided international properties and exploration expertise. Falconbridge then developed operations in the Dominican Republic, Quebec, Ontario, the Caribbean, Latin America and the United States. Its assets eventually included nickel, copper, cobalt, zinc, lead, aluminum, alumina, precious metals and recycling businesses. The company combined mining with processing and technological development. It patented a chlorine-leach nickel-refining process in 1977. In Sudbury, new smelting and sulfuric-acid facilities helped reduce sulfur-dioxide emissions and converted a pollutant into a marketable chemical. The depletion of the original Falconbridge mine in the 1980s did not end the company's regional presence: production shifted to other Sudbury mines, and the group acquired or developed Kidd, Montcalm, Raglan and other operations. Falconbridge merged with Noranda in 2005. The enlarged business inherited aluminum and recycling activities and became the subject of a contested takeover involving Inco, Xstrata and other mining companies. Xstrata completed its acquisition in August 2006. The business continued as Xstrata Nickel, and the legal company name was changed to Xstrata Canada Corporation in October 2007. Xstrata later merged with Glencore in 2013. Falconbridge's social history is closely linked to Sudbury. Its company town became an incorporated community and was eventually absorbed into Greater Sudbury. The company was a major employer, and competition between Falconbridge and Inco influenced local labor politics and community identity. Pollution also affected nearby communities, including Happy Valley, which was abandoned in the 1960s. The former Edison Building was later donated for civic use, preserving a physical reminder of the company's regional role.

Products and positioning
An integrated, internationally active mining and metals group combining exploration, underground and open-pit mining, concentration, smelting, refining, recycling and metal marketing. Its historical identity was rooted in Canadian nickel and copper, while later acquisitions created a diversified base-metals, aluminum and recycling portfolio.
Mining and smelting · 1930
Sudbury nickel and copper
Falconbridge's historic core was the Sudbury Basin, where it operated underground mines, concentrators, a nickel smelter, sulfuric-acid facilities and a technology center. The operations produced nickel and copper with associated cobalt and platinum-group materials. By 2006, principal mines included Craig, Fraser and Thayer Lindsley, with Nickel Rim South in development.
Nickel refining · 1929
Falconbridge Nikkelverk
The Kristiansand, Norway refining operation originated with Falconbridge's 1929 acquisition of Kristiansand Nikkelraffineringsverk. It became the group's principal nickel-refining site after refining was no longer conducted in Sudbury and also supported cobalt recovery.
Copper-zinc mining and processing
Kidd Mine and Metallurgical Site
The Timmins, Ontario complex combined an underground copper-zinc mine with concentration, copper smelting and refining, zinc processing, indium and cadmium plants, and sulfuric-acid facilities. It was one of Falconbridge's major Canadian integrated metals complexes.
