"China's refined copper demand posted double-digit percentage growth for 7 of the last 11 years to reach 7.63 million tonnes in 2011, according to CRU Group. Even if growth averages 7 percent over the coming years, it will still gobble up an additional 530,000 tonnes each year - an amount topping the world's No. 9 producer Poland's annual output.

To fill that demand is no small feat, especially for a metal which has been in supply deficit for most of the past decade and with world supplies are only expected to rise by 770,000 tonnes in 2012, according to estimates by consultancy Brook Hunt."
