Nov 28 (Reuters) - Copper prices on the London Metal Exchange set a new all-time high above $11,200 on Friday, spurred by a weaker dollar, lower output in top producer Chile in October and planned production cuts by Chinese smelters.

Benchmark LME three-month copper rose as much as 2.5% to $11,210.50, beating the previous record high of $11,200 set on October 29.
