Rio Tinto (corporation)

Rio Tinto Group is a British-Australian multinational company that is the world's second largest metals and mining corporation. It was founded in 1873 when a group of investors purchased a mine complex on the Río Tinto, in Huelva, Spain, from the Spanish government. It has grown through a long series of mergers and acquisitions. Although primarily focused on extraction of minerals, it also has significant operations in refining, particularly the refining of bauxite and iron ore. It has joint head offices in London, England and Melbourne, Australia.

Rio Tinto is a dual-listed company, traded on both the London Stock Exchange, where it is a component of the FTSE 100 Index, and the Australian Securities Exchange, where it is a component of the S&P/ASX 200 index. American depositary shares of Rio Tinto's British branch are also traded on the New York Stock Exchange, giving it listings on three major stock exchanges. In the 2020 ''Forbes'' Global 2000, it was ranked the world's 114th-largest public company.

Rio Tinto has faced criticism by environmental groups as well as the government of Norway for the environmental impacts of its mining activities. Provided by Wikipedia
