摘要
Water is among the most largely consumed material in and an inseparable component of the processes used for mineral processing. At Sarcheshmeh Copper Complex (located in Kerman, southeastern Iran), drinkable water from local water wells is used for the heap leaching of the copper. In recent years, the water crisis in Iran has intensified the necessity of performing widespread researches on the water recycling and substitution with other sources of water in this mine. In the present work, alternative sources of water were investigated for substituting the well water for heap leaching process of copper. Three alternatives were studied for this purpose: seawater, the mine drainage water, and the raffinate of the process. Initial evaluation of the performance of the considered alternative sources of water was done using rolling bottle tests at different values of pH. Based on the results, the raffinate exhibited inappropriate performance due to the presence of various ions in its composition, while the seawater and the mine drainage water showed better results. In order to further simulate the heap leaching process, column leaching tests were performed using seawater and the mine drainage water at three size distributions corresponding to the P80, values of 8900, 12,700, and 25,400 μn. The obtained results indicated that the particles corresponding to the P80 of 12,700-μm exhibited the highest performance, as compared to the other size distributions. Compared to the other water sources, the seawater showed better kinetics and recovery at pH = 1.5 together with the lowest acid consumption at all of the considered size distributions. Moreover, compared to the other alternatives, the seawater could better dissolve the sulfide minerals probably duo to the presence of chloride ion in seawater. © 2020 GDMB Gesellschaft fur Bergbau, Metallurgie, Rohstoff- und Umwelttechnik e.V..
