Asarco celebrated its 100th anniversary of operations in Arizona, on Feb. 24. Ryan Randazzo of the Arizona Republic wrote up a nice short history of the company, concluding with a list of its current operations:
Ray and Hayden operations: A large open-pit mine, two concentrators, smelter and other facilities in Pinal and Gila counties. Produced 83.3 million pounds of copper cathode and 350.3 million pounds of copper anode in 2010. Spent $294.5 million on materials, energy, supplies, etc. that year. Employs about 1,400 people.
