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.
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.
