The most traded February copper contract on the Shanghai Futures Exchange gained 1 percent to 50,610 yuan ($8,300) a tonne on Friday as prices buoyed by steady if slowly growing demand and a temporary shortfall in supply after a typhoon-hit Philippine smelter halted some shipments. "We broke through a significant support this week and the market is consolidating," said Jonathan Barratt, chief executive of commodity research firm Barratt's Bulletin in Sydney.
