History YEAR 1873 Our Founding: from an ancient mine to the world's #1 copper producer Led by Scottish entrepreneur Hugh Matheson, a British-European investor group buys the Rio Tinto mines in Spain in 1873, constructed new processing facilities and introduced new techniques that, from 1877-91, allow the new Rio Tinto Company to transform an operation that had once supplied the ancient Greeks and Romans into the world’s number one copper producer.
