Rio Tinto Business Description

Address 6 St James’s Square, London, GBR, SW1Y 4AD
Rio Tinto is a global diversified miner. Iron ore is its major commodity, with lesser contributions from copper and aluminum.

The two operate as a single business entity, with shareholders in each company having equivalent economic and voting rights. Major assets included the Pilbara iron ore operations, a 30% stake in the Escondida copper mine, 66%-ownership of the Oyu Tolgoi copper mine in Mongolia, the Weipa and Gove bauxite mines in Australia, and six hydro-powered aluminum smelters in Canada.
