Rio copper output hit hard after Binqham Canyon landslide

摘要

RIO Tinto said it expected to lose 125,000t of mined copper in 2013 following a landslide at its Bingham Canyon mine near Salt Lake City, Utah. The company said more than 150Mt of material swept down the north-eastern wall on April 10. Chief executive Sam Walsh said the collapse would have a "significant impact" on the company's copper production this year. Rio said mining operations at Bingham had been suspended and the site's concentrator shut down, although smelting and refining were ongoing, albeit at a limited capacity.
