Rio Tinto: the mines it operates or owns, and what they report
Rio Tinto is a listed company headquartered in United Kingdom (NYSE: RIO (ADS); plc registered office 6 St James's Square, London; Rio Tinto Limited at Level 43, 120 Collins Street, Melbourne). This site lists 26 operations tied to it, for bauxite, iron ore, copper and aluminum: it operates 16 and holds an interest in 10 more. On the operations here where a whole-operation figure can be stated (in metal content, or as the commodity page says for ore and smelted metal), its interests add up to about 3,380,000 tonnes of primary aluminum (4.6% of world output) and 58,645,000 tonnes of bauxite (13% of world output) and 609,400 tonnes of copper (2.6% of world output) and 289,612,800 tonnes of iron ore as ore, not iron content (11% of world output). That leaves out operations without such a figure, so it is not the company's total.
