Rio Tinto is a diversified global mining company. It primarily focuses on producing industrial metals, including the three most widely used ones -- iron ore, aluminum, and copper. It also has a growing lithium business.
Rio Tinto is a global leader in producing aluminum. The company operates large-scale, high-quality bauxite mines, alumina refineries, and aluminum smelters. It’s a leader in efforts to use low-cost, carbon-free hydroelectricity to power aluminum operations. In early 2026, the company teamed up with China's Chinalco to acquire a controlling stake in Brazilian aluminum maker CBA in a deal valued at more than $900 million.
Rio Tinto is also a top producer of iron ore, a key ingredient in steel, the most widely used metal alloy in the world. The company’s iron ore operations in Australia comprise an integrated network of world-class mining assets, processing hubs, rail lines, and port terminals that help keep costs low. Rio Tinto and its partner Hancock Prospecting approved the Hope Downs 2 iron ore project in Australia to expand its iron ore business in June 2025.
It also has a large-scale copper business. It controls the massive Oyu Tolgoi mining project in Mongolia. The company also owns the Winu copper-gold project in Australia, which it's seeking to develop.
Finally, Rio Tinto approved the $2.5 billion Rincon project in Argentina in late 2024, its first commercial-scale lithium operation. It also acquired Arcadium Lithium for $6.7 billion in early 2025 to create a world-class lithium business to complement its leading iron ore, aluminum, and copper operations.
