Abstract: Acid mine drainage (AMD) is a mining-related problem that is causing harm to the natural ecosystem. The AMD originates from oxidized and sulfide ore stockpiles and contains high concentrations of dissolved copper and other contaminants. Therefore, many applications have been taken account into to process this highly acidic stream. In this research, Aspen Plus software is employed to simulate and analyze copper and water recovery efficiency of AMD generated from the stockpile of the Erdenetiin Ovoo deposit in at Gal Sentii LLC, Mongolia. The simulation incorporates a membrane filtration train consisting of ultrafiltration (UF) followed by two stages of nanofiltration (NF1 and NF2), modeled under steady-state conditions using the ELECNRTL thermodynamic method. Results show that the integrated system achieves high copper removal efficiency, with NF1 and NF2 reaching 98.99% and 100% separation, respectively. Water recovery remained effective throughout the process, reaching 90.08% in UF, 83.14% in NF1, and 99.90% in NF2. Total water hardness was reduced from 5918.81 mg/L to 0 mg/L, meeting the Mongolian MNS 4943:2015 standard for clean water. Although the permeate remained slightly acidic (pH ~ 3.67–3.93), the simulation confirms that membrane-based treatment is a viable strategy for both copper recovery and AMD remediation in cold-climate mining environments such as Mongolia.
