Rio Tinto has announced that its global iron ore production for the second quarter of 2010 fell 2% compared to 2009.
In its second quarter operations review, the mining giant said its iron ore output dropped to 43.6 million metric tons from 44.6 million tons a year earlier.
The company’s mined copper and gold production fell 19% and 34% respectively, primarily due to lower grades at Kennecott Utah Copper, US, and Grasberg, Indonesia.
However, Rio increased its annual forecast for its share of mined copper production to 690,000t from 680,000t.
Rio’s hard coking coal production climbed 26% in the second quarter of 2009 following increased investment at its Queensland operations in Australia.
The company will also invest $469m in constructing the Kennecott Eagle nickel and copper mine in Michigan, US, after receiving final environmental approvals, with first production expected in late 2013.
