Oct 14 (Reuters) - Copper in London advanced on Wednesday, as the threat of mine supply disruptions in Chile, a top producer of the industrial metal, and stronger consumption from leading consumer China supported prices.

Three-month copper on the London Metal Exchange rose 0.3% to $6,713.50 a tonne by 0346 GMT, while the most-traded November copper contract on the Shanghai Futures Exchange fell 0.4% to 51,330 yuan ($7,615.05) a tonne.

Though the Escondida mine in Chile could continue to operate even if supervisors walked off the job, a strike could lead to production bottlenecks or slowdowns.

Canada's Lundin Mining will talk with the Mina union at its Candelaria copper deposit to try to end a strike, while supervisors at Escondida mine and mine operator BHP will extend negotiations in an attempt to stave off a strike at the world's largest copper deposit.

"Physical demand picked up a little month-on-month, but is still lower year-on-year. (October is) supposed to be strong, but it's not that strong (yet)," said CRU copper analyst He Tianyu, adding that demand might gather pace again in two weeks.
