Copper climbs to highest in nearly a month
Copper climbed to the highest in nearly a month on Wednesday on largely upbeat economic data, but the upside was capped by caution about weak underlying metals demand and a setback in US growth.
Copper prices surged more than 3 per cent to 13-month highs on Wednesday, reaching above $3 per pound in New York, as the dollar weakened and BHP Billiton declared force majeure at the world's fourth-largest copper mine.
