Copper prices rose by Rs 1.25 to Rs 434.25 per kg in futures trade today as speculators enlarged their positions on the back of a firming global trend.
Trading sentiment turned better after demand for copper in China, the world's biggest user, rose by 8 per cent this year, depleting global supplies and boosting prices.
At the Multi Commodity Exchange, copper for August delivery rose by Rs 1.25, or 0.29% to Rs 434.25 per kg, with a business turnover of 11,052 lots.
Similarly, the metal for November delivery edged up Rs 1.10, or 0.25%, to Rs 440.05 per kg, with an open interest of 937 lots.
Market analysts said besides a firming trend overseas, increased demand in the spot market mainly led to the rise in copper prices at futures trade.
Meanwhile, copper for three-month delivery gained 0.2% to $9,672 a tonne on the London Metal Exchange.
