HAYDEN, Ariz. (AP) - Tucson, Arizona-based copper-mining giant Asarco is preparing to shut down operations of its Hayden concentrator, resulting in the potential loss of more than 200 jobs.

The company said Friday it plans to indefinitely cease operations of the concentrator. It will also reduce new stripping to supply its Ray mine leaching operations. It cited a large drop in copper prices that began in 2011 and current global market conditions for the decision.

The changes may affect 211 workers and cut total company copper output by about 17 percent.

Asarco is a subsidiary company of Groupo Mexico with 2,300 workers. It owns mines, mills and a smelter near Tucson as well as a refinery in Amarillo, Texas.

The concentrator will likely close within 60 days, with mine cuts occurring more quickly.
