The price of copper on the London Metal Exchange rose 0.5% to $14,229.50 a ton, breaking a three-week decline, Bloomberg reports. The recovery in quotes was recorded by the easing of investors' concerns about a slowdown in global economic growth amid the stabilization of the technology sector and lower oil prices. Additional support for the metal is provided by signs of supply shortages: Chile's copper production at the end of the last quarter fell to the lowest level in at least two decades.
