News	April 6, 2010 - BNamericas reported that Chilean state minerals company Enami will see its Hernán Videla Lira smelting plant's 2010 production reduced by close to 3% as a result of 10 day stoppage at the facility. Enami said in a filling submitted to securities regulator SVS that the plant, also known as Paipote, stopped operations on March 31st 2010 after a hot gas fan at one of its two sulfuric acid plants failed, something the company was unable to forecast. The facility, located in northern region III is Chile's oldest smelting plant and Enami's largest, producing close to 350,000 tonne per year of fire refined copper in the form of anodes to be converted into cathodes at state copper producer Codelco's Ventanas refinery in central region V. The site also produces close to 290,000 tonnes per year of sulfuric acid at the 2 plants, which treat sulfur gases coming from the smelting process.
