Copper prices briefly dipped to a session low in choppy trade on Wednesday, as nervousness about the health of the economy persisted, although a weak dollar and better-than-expected data helped keep falls in check.

Benchmark copper on the London Metal Exchange (LME) dipped to a low of $6,752 a tonne, giving back some gains in the wake of data showing U.S. private sector employers added more jobs than expected in September. At 1241 GMT, the metal traded at $6,797 a tonne, down slightly from Tuesday's close of $6,800.
