ASARCO Ray Mine, located 64 miles southeast of Phoenix and 70 miles northeast of Tucson, is a significant copper mining operation. ASARCO Ray Mine has been a significant competitor in copper production for several decades. With its robust infrastructure, including the mill, SX-EW plant, and storage facilities, it is poised to continue operations for many years, benefiting from decades of copper reserves.

This ensures a reliable future for copper production in the region.

It encompasses several components critical to its operations:

Open-pit mining:
The Ray Mine extracts copper ore from an open-pit mine, which has been operational since the late 1980s.

Leach and Barren Rock Deposition Area:
This area is used for the leaching process, where copper is extracted from ore using a chemical solution. The barren rock deposition area stores waste materials from this process.

Ray Mill:
The concentrator at Ray processes up to 30,000 tons of ore per day. Through flotation, copper concentrate is produced, which is a key step before further refining.

Solvent Extraction-Electrowinning Plant (SX-EW):
This plant uses a chemical process to extract copper from the leach solution and electro-wines copper cathodes. The SX-EW method is an efficient way to produce high-purity copper directly from ore.

Tailings Deposition Facility:
The tailings produced by the flotation process at the concentrator are stored in a designated facility. These tailings consist of waste materials that no longer contain commercially viable amounts of copper.
