Shanghai copper soars

Copper rose sharply on Tuesday as investors returned from a three-day weekend in most of Asia with a renewed appetite for industrial commodities. The gains in both London Metal Exchange and Shanghai Futures Exchange copper were aided by advances in Asian stocks on easing concerns over North Korea, commodities traders said.
The most-traded copper contract on the Shanghai Futures Exchange rose 1.2 percent to 46,790 yuan ($6,785) a tonne. Both exchanges were closed on Monday for Labour Day. Thousands of workers from the Indonesian unit of Freeport McMoRan Inc staged a rally near its Papua mine on Monday, a union leader said, protesting against layoffs by the miner due to a contract dispute with the government.
