Billed as one of the largest metal and mining company, Rio Tinto came into being in 1873. Hugh Matheson led a number of multinational investors to purchase a mine from the Spain government in Huelva Spain, which later on led to the formation of the company. The investment syndicate included Deutsche Bank, which owned 56% of the mine, Matheson 24% and civil engineering firm Clark 20%. Control of the company was passed to the Rothschild family at the end of the 1880s.
The company is currently headquartered in London, England and engages in exploration mining and processing of natural resources worldwide. Some of the key minerals it mines include silver, gold, diamonds, aluminum, borates among others.
