(Adds detail, company statement)
SANTIAGO, Jan 29 (Reuters) - Chile's state miner Codelco said it had halted operations at a crushing plant at its El Teniente copper mine on Thursday following a fire at the plant, although other parts of the project were unaffected.
The cause of the fire at the crushing plant in Colon Alto is being investigated and was brought under control at about 3 p.m. local time (1800 GMT), about two hours after it started, said the company, the world's top copper producer, in a statement.
No one had been injured, it said.
Crushing plants allow material from the mine to be broken up to a size that eases processing.
El Teniente in central Chile produced 423,100 tonnes of copper between January and November 2014.
