Wastewater from copper process industries in terms of volume of production, environmental pollution and the cost of treatment and disposal is important. In addition to the economic benefits, the recovery of the wastewater reduces the pollutant load in the environment. So the necessity of reviewing of various methods to reduce water consumption and wastewater production can be apprehended. This study has investigated the minimization of water consumption and wastewater in Khatoon Abad copper mine. The conventional method of reducing water consumption and a new technology by the name of water pinch for this purpose has been explained. In this research, water pinch technology has been examined for the three pollutant indices (TSS, TDS and turbidity) in three commonly used units in Khatoon Abad copper complex. For TSS, TDS and turbidity as pollutant indices, totally 614, 525 and 451 cubic meters per day of raw water consumption equivalent to 40.96, 35 and 30 percent can be saved, respectively.
