The overall world production of refined copper in 2002 amounted to 15,245,000 tonnes which represented 77.9% of total refinery capacity and reflected a 1.6% decrease from 2001 (CRU, 2003). The US refined output (primary and secondary) in 2002 was 1,545,000 tonnes while mine output of 1,130,000 tonnes was supplemented by scrap recycling and imports.
