SANTIAGO, Feb 29 (Reuters) - Chile's state-owned mining company, Codelco, said on Monday that it has started to normalize operations at its massive Andina mine following a pipeline burst last week that forced it to stop a production line.
Codelco, the world's top copper producer, reported on Thursday that it was suspending the production line after an underground pipe carrying material from a concentrator to a filtration plant burst.
Although the spill was quickly cut off, it flowed into a river. Codelco said it was monitoring water quality at the river and that a local water utility had said the water remained safe for human consumption.
Last year, Andina, which is near the capital, Santiago, produced 224,300 tonnes of copper, about 13 percent of Codelco's 2015 production of 1.73 million tonnes. (Reporting by Anthony Esposito; Editing by Jonathan Oatis)
