Water Consumption at Copper Mines in Arizona
Copper minerals generally occur as oxides or sulfides. These require different treatments for extraction of the metal. The oxides are exposed to acid in a heap leach; this liberates the copper ions and the resulting solution is then sent to the solvent extraction (SX) process followed by electrowinning (EW) of the copper.
