(Recasts to lead with ShFE copper, updates prices) BEIJING, Jan 23 (Reuters) - Shanghai copper prices gained ground on Tuesday amid a persistent weak dollar, even as official data showed China churned out a record volume of refined copper in December, suggesting the world's biggest copper consumer is well supplied. A weak dollar makes metals cheaper for holders of other currencies and supports prices, and the greenback's dive as a result of the U.S. government shutdown had seen copper climb by 0.4 percent in both Shanghai and London on Monday. "We think the recent copper price rebound is mostly driven dollar weakness reversal may weigh down on copper prices, in our view." While China's refined copper output hit an all-time high in December, Argonaut noted that unwrought copper imports fell by 5 percent in 2017. "The reduced import appetite reflects China's sluggish copper demand, especially in the power sector," it added.
