ASARCO’s copper plant investment yields two-for-one: cleaner air and longer life

ASARCO’s Hayden, Ariz., copper smelter has been undergoing a major upgrade that will enable the operation to capture nearly all its SO2 emissions by the end of 2018. The company is investing approximately $180 million into its Hayden plant to fund improvements that both satisfy a consent decree reached with the EPA and secure Hayden’s operation for the future.
