Rio Tinto Acquisitions
Throughout its history, Rio Tinto has pursued strategic acquisitions that strengthened its portfolio across multiple commodities and geographic regions. These transactions transformed the company from a single-mine operation in Spain to a truly global mining powerhouse.
The 1968 acquisition of US Borax represented a significant entry into industrial minerals, bringing borates operations in California’s Death Valley. This business became integral to the company’s minerals segment, producing materials used in glass, ceramics, agriculture and cleaning products. The acquisition included the iconic 20-mule team brand and established Rio Tinto in the North American market.
A transformative moment came in 1989 with the purchase of BP Minerals. This landmark acquisition delivered major assets including Kennecott Utah Copper, one of North America’s largest copper operations, Quebec Iron & Titanium facilities, and interests in Australian coal through Coal & Allied. The transaction marked Rio Tinto’s strategic pivot to concentrate exclusively on mining, divesting previous holdings in chemicals, cement, oil and gas.
The 2000 acquisition of North Limited strengthened Australian operations, particularly in iron ore and coal. By 2007, Rio Tinto completed the 38 billion USD purchase of Canada’s Alcan Inc, dramatically expanding aluminum capabilities. This created Rio Tinto Alcan, integrating bauxite mining, alumina refining and aluminum smelting operations across multiple continents, though some assets were later divested.
More recently, the 2024-2025 acquisition of Arcadium Lithium for 6.7 billion USD marked Rio Tinto’s major entry into battery materials. Completed in March 2025, the transaction brought lithium operations spanning Argentina, Australia, Canada and the United States, with annual production capacity of 75,000 tonnes of lithium carbonate equivalent. Renamed Rio Tinto Lithium, the business provides access to electric vehicle and renewable energy markets, targeting capacity expansion to over 200,000 tonnes per year by 2028 to serve growing demand for energy transition materials.
These strategic acquisitions reflect Rio Tinto’s evolution from Spanish copper mining to diversified global resources, positioning the company across iron ore, aluminum, copper, minerals and now lithium. Each transaction strengthened competitive positioning in essential commodities while expanding geographic presence and technical capabilities.
