Sulfide tailings and sulfide effluents are important in terms of acidification potential. The results of preliminary studies indicate the possibility of acidic effluent formation and this process has followed an upward trend along with decreasing pH and increasing the concentration of contaminants in the effluent in recent years. Preliminary studies indicate the possibility of lowering the pH in the coming years, in which case it is possible to release large amounts of aluminum ions, iron and other heavy elements. In this study, in order to deal with inventory and future problems, 300 liters of acid drainage reagent sample was prepared in Pakhir valley and a series of mineralization and leaching tests were performed on it. Based on the results of the extraction process of valuable elements along with heavy elements in the above sample and due to the great importance of environmental considerations in the area, while stating the need for additional studies to identify and control future oxidation of mine tailings, the proposed circuit to control and inhibit acid drainage. Wastewater treatment and reconstruction was also provided.
