Copper ended higher on Tuesday, bouncing up from a two-week low as a pullback in crude oil prices eased concerns about inflation and allowed traders to focus on longer-term demand prospects. "The driving force behind copper is demand, and I think will continue to be demand," said Bill O'Neill, partner of LOGIC Advisors in Upper Saddle River, New Jersey.
In New York, COMEX May copper rose 1.15 cents to settle at $4.3385 per lb, after dealing between $4.2540 and $4.3585.
