Facility Information

On Oct. 21, 2022, ADEQ received the Class II Air Quality Permit application for the Copper World Project from Copper World, Inc.

The Copper World Project is located approximately 28 miles southeast of Tucson, Arizona in Pima County and about 12 miles southeast of Sahuarita, Arizona. The Copper World Project will be developed as an open-pit mining operation. Both sulfide and oxide ore will be mined and beneficiated. The project will include a milling and flotation circuit for the processing of sulfide ore along with conventional tailings disposal. A heap leach facility (HLF) is planned that includes a lined heap leach pad (HLP) and associated lined ponds for the leaching of copper from oxide ore. The project also includes a solvent extraction and electrowinning (SX-EW) plant for processing of copper-rich solutions from the heap leach circuit and from a separate copper concentrate leach circuit.
