Anglo American's name might be a little misleading -- it has never been American. The UK-based company owns significant stakes in global producers of platinum (75% of Anglo Platinum) and diamonds (85% of De Beers S.A.). In addition, Anglo American has interests in ferrous and base metals and industrial minerals. It ranks among the world's largest iron ore producers and is also a leading copper producer. Anglo is one of the world's largest coal miners and exporters of metallurgical coal, a key raw material in steel production. It also produces thermal coal, used to generate electricity. The founding Oppenheimer family no longer controls Anglo American.
