Asarco Incorporated

ASARCO was organized in 1899 as American Smelting And Refining COmpany. Originally a consolidation of a number of lead-silver smelting companies, the Company has evolved over the years into an integrated producer of copper, and other metals.

The Company is a fully integrated miner, smelter and refiner of copper in the United States. ASARCO’s domestic mines annually produce approximately 350 – 400 million pounds of copper. Significant copper mines include the Mission, Silver Bell and the Ray open-pit mines, all three in Arizona.

ASARCO has solvent extraction/electrowinning product at our Ray and Silver Bell mines.  ASARCO operates a copper smelter in Hayden, Arizona, which produces almost half a billion pounds of anodes annually.  The Company’s Amarillo Copper Refinery in Texas and the SX/EW plants at the Ray and Silver Bell mines produce about 375 million pounds of refined copper per year.

ASARCO recognizes and believes that all operations and activities of the Company should be conducted responsibly and in a manner designed to protect the health and safety of its employees, its customers, the public and the environment. ASARCO’s operations interact with the environment daily, and consideration of these concerns must be a way of life within the Company. ASARCO is committed to a responsible management of our natural resources.
