SANTIAGO, March 8 (Reuters) - A smelter at Codelco's largest copper mine that was knocked offline by last week's massive earthquake in Chile was up and running again on Monday, a spokesman for the state-owned company said.
"The smelter is now 100 percent normalized," the spokesman told Reuters on the condition of anonymity because he is not authorized to speak on the record.
The smelter at the El Teniente mine about 80 km (50 miles) south of the capital Santiago was forced to shut down in the wake of the 8.8-magnitude quake that rocked Chile on Feb. 27.
The quake, which severely damaged power lines and other key infrastructure in the South American country, compromised less than 0.5 percent of Codelco's [CODEL.UL] annual output, the company said last week.
Codelco, which mined 1.7 million tonnes of copper last year, is the world's top producer of the metal.
Chile's top two oil refineries were also damaged by the quake and remain offline. The smaller of the two, the Aconcagua refinery, could resume operations later this week, union and company sources said on Monday.
The larger Bio Bio refinery, which is located near the quake's epicenter, could remain offline for two to three months while it is being repaired, a union leader told Reuters on Saturday.
