Copper marches to one-week high

Copper prices rose on Tuesday to a one-week high as the dollar gave up ground to a three-week trough, underpinning the industrial metal. 

Copper last traded at $2.592 a pound, up from the opening of $2.565, with a session-high at $2.598, and a low at $2.558. 

Copper's rise comes as the dollar tumbles against a basket of rivals, heaping demand on the metal despite gold's decline today.

Geopolitical tensions in the Korean peninsula pushed the dollar down today, especially amid growing risk appetite in the markets after the first round result of French elections. 

On the other hand, copper was buoyed after mining giant Rio Tinto forecast a drop in production levels in its quarterly report due to workers strikes and production stoppages in two of the biggest copper mines, boosting prices.
