Copper futures ended higher on Wednesday after US lawmakers approved a $1 trillion infrastructure spending bill, while weakness in US dollar also supported copper prices. However, some gains were limited by easing supply worries following dwindling chances of a strike at Escondida, the world’s largest copper mine in Chile.
Copper futures for September delivery gained $0.0135 to settle at $4.3675 a pound on the Comex metals division of New York Mercantile Exchange. Copper on the London Metal Exchange was down 0.09 percent at $9,512.00 a ton.
