Rio Algom Limited is a Canadian mining company that has existed since 1960. The company was founded by Rio Tinto through the merger of its four Canadian uranium mining operations: Algom Uranium Mines Limited, Milliken Lake Uranium Mines Limited, Northspan Uranium Mines Limited, and Pronto Uranium Mines Limited. In October 2000, Rio Algom was acquired outright by Billiton plc of London, which a year later merged with the Broken Hill Proprietary Company (BHP) of Sydney. Rio Algom has remained a wholly-owned subsidiary of BHP since 2001.
It operated many uranium mines and mills in the Elliot Lake region of Ontario, Canada, including the Lacnor Mine, Nordic Mine, Panel Mine, Pronto Mine, Quirke Mine, Milliken Mine, Stanleigh Mine, and the Spanish-American Mine. These operated from the 1950s to the 1990s. [1]
It got ownership of a uranium mill in the Ambrosia Lake region of New Mexico when it purchased the Quivira Mining Corporation from Kerr-McGee in 1989. The mill had only been active from 1958-1985. However from 1989-2002 it produced uranium from recovered mine-water. [2] [3] [4]
The 2017 performance of Rio Algom, who own nine decommissioned uranium mines at Elliot Lake, was described as "below expectations" by the Canadian Nuclear Safety Commission. [5] The commission reported radium releases above limits at the Stanleigh effluent treatment plant, prompting engineering work plus increased site monitoring by Rio Algom. [5]
Rio Algom bought the Quivira Mining Corporation (a subsidiary of Kerr-McGee) in 1989. [3]
Rio Algom was bought by Billiton in 2000. [6] [1] [2] [3] [4]

Elliot Lake is a city in Algoma District, Ontario, Canada. It is north of Lake Huron, midway between the cities of Sudbury and Sault Ste. Marie in the Northern Ontario region. Once dubbed the "uranium capital of the world," Elliot Lake has since diversified to a hub for advanced manufacturing, forest harvesting, mine reclamation expertise, retirement living, all-season tourism and remote work.
The Kerr-McGee Corporation, founded in 1929, was an American energy company involved in oil exploration, production of crude oil, natural gas, perchlorate and uranium mining and milling in various countries. On June 23, 2006, Anadarko Petroleum acquired Kerr-McGee in an all-cash transaction totalling $16.5 billion plus $2.6 billion in debt and all operations moved from their base in Oklahoma, United States. As a result of further acquisitions, most of the former Kerr-McGee is now part of Occidental Petroleum.

Radioactive ores were first extracted in South Australia at Radium Hill in 1906 and Mount Painter in 1911. 2,000 tons of ore were treated to recover radium for medical use. Several hundred kilograms of uranium were also produced for use in ceramic glazes.
Canada is the world's second-largest producer of uranium, behind Kazakhstan. In 2009, 20% of the world's primary uranium production came from mines in Canada. 14.5% of the world production came from one mine, McArthur River. Currently, the only producing area in Canada is northern Saskatchewan, although other areas have had active mines in the past.
