Rio Tinto Limited
(ASX:RIO) has shut one of the world's largest copper mines in the US after a massive landslide.
The landslide at the Bingham Canyon Mine pit wall was expected amid warning signs of ground movement since February.
The news comes as Rio prepares to release its first quarter production report this week.
The mine represents 17 per cent of the US's total copper output.
Rio Tinto reported a net loss of $2.9 billion in the 2012 financial year.
