Shanghai's third-month copper gained nearly one percent to close at 69,250 yuan ($10,375) a tonne on Tuesday. Production at Chinese copper smelters is unlikely to be hit in the near term by Collahuasi incident, as smelters hold more-than-enough concentrate stocks, smelter officials said on Tuesday.
The world's No 3 copper mine, Chile's Collahuasi, said on Monday it halted shipments of copper concentrate after a weekend accident shut its key sea port terminal, fuelling global supply worries.
