In a month of copper strikes, world number 3 Collahuasi’s must count as shortest
Reuters reports unionised Chilean workers at Collahuasi, the world's third most productive copper mine, halted production on Saturday in a strike demanding a wage bonus, but were back at work on Sunday after after reaching an agreement with management, the company and union said.
Collahuasi is owned by Switzerland's Xstrata and the Britain-based Anglo American. Collahuasi produced 504,000 tonnes of copper in 2010, when output was hit by a month-long strike. The mine expects to produce 500,000 tonnes of copper this year. It supplies roughly 3% of the world's copper, half that of Chile's other giant copper mine Escondida.
