“…This study also establishes that the examined AMD displays higher contaminant levels compared to similar occurrences on the same island in Sumatera, Indonesia [20]. The prominent Fe concentration identified in this study is attributed to a combination of chemical and bacterial processes [29]. Furthermore, the low pH level evident in this particular AMD presents an additional hazard to the surrounding ecosystem of this abandoned mining site.…”

Coal-mining activities have well-documented adverse effects on both the environment and human health. Acid mine drainage, a pivotal concern, necessitates effective interventions. This study introduces a novel solution: a modified constructed wetlands crafted exclusively from waste materials, ensuring cost-effectiveness. The innovation yielded exceptional results, achieving a noteworthy reduction of up to 99% in heavy metal concentrations, alongside swift pH normalization. What sets this study apart is its potential beyond the laboratory setting; the utilization of waste materials and low-cost methodologies underscores its scalability and practicality. This solution addresses immediate challenges and showcases promise for real-world implementation. Moreover, the results of the study extend to its insights, which offer a comprehensive examination of the method’s reusability prospects, illuminating its sustained impacts; the recommendations for future action enhance its practical significance. This study marks a significant advancement in tackling acid mine drainage. The modified constructed wetlands, driven by cost-effective waste materials, embody scalable and sustainable potential. With its holistic outlook and strategic roadmap, this study holds the key to transforming acid mine drainage challenges, particularly in rural and developing regions.

“…The study, realized in the earlier period, has confirmed that very serious environmental impacts are detected 30 km along the Bela River. Inflowing of the untreated AMD water from an overburden disposal as well as from flotation tailing dumps will continue to significantly impact the local and regional water resources [40].…”

This paper considers the impact of copper mining-influenced water and metallurgical wastewater on the surface water in the Bor area, Serbia. Sampling, realized through the four campaigns (2020–2021), confirmed that both types of water, discharged without appropriate treatment in the Bor River, had a signific impact on the concentration of metal ions, pH and electrical conductivity on the watercourse in the Bor area. The highest concentrations of the following metal ions, Cu-271 mg/L, As-25991 μg/L, Ni-13856 μg/L, Cd-2627 μg/L, and Pb-2855 μg/L, were registered in the metallurgical wastewater samples. After changes occurred in the copper production process by stopping the discharge of untreated wastewater into the Bor River, the concentrations of monitored elements were drastically decreased. In the period 2022–2024, the concentration values for Cu, As and Pb ions were below the maximum allowable value, and the concentration values of Ni and Cd ions were also decreased. The values for pH and electrical conductivity were in the maximum allowable range. The return of wastewater to the copper production process would lead to both a reduction in the primary water consumption and reduction in the negative impact on the environment.

“…1), which is fed by surface water drainage and seepage. From seepage of the disposed waste materials and /or from accumulation of leach solution from heap leachings, this water is highly contaminated with the site specific compounds like sulphate, iron and trace metal elements concurrent to low pH-values below 3 (Gardić et al 2017;Markovic et al 2020). Also, the colour of the water is red (Fig.…”

“…Chemical characterization of the Robule Lake wastewater samples treated byMarkovic et al 2020 Results of neutralization tests, presented in Table11, show that Fe removal degree on pH 4 was 99.7% mass. This value confirmed that Fe conversion into the insoluble hydroxide form was almost finished on pH 4 and it was the good option for separation the Fe ions from the other ions elements that existed in AMD from the Robule Lake.…”

Robule Lake is located in Eastern Serbia, near city of Bor, known for copper production, and it is being influenced by waste materials from mining activities. For the purification of water from Robule Lake, contaminated with various metal ions (Fe, Cu, Zn, Mn, Cd, Ni, etc.), acid 2 mine drainage (AMD) treatment methods such as: passive treatment method, sequential neutralization, ion exchange, adsorption process based on low cost adsorbents, adsorption process based on natural zeolits, electrodialysis, filtration with nanofiltration membranes, and reverse osmosis, were evaluated by following MCDM methods: TOPSIS, VIKOR, MOOSRA; WASPAS, and CoCoSo. Criteria used for the evaluation were: efficiency in the metal ions removal and the quality of the purified water, necessity of pre-treatment and / or post-treatment of treated water, possibility of using the generated waste, capital costs, operating and maintenance costs, needed area, and sensitivity of the method. The results of the MCDM analysis showed that sequential neutralization was the most appropriate for this wastewater, while passive treatment system and ion exchange were ranked as second and third, respectively.After the selection of AMD treatment method, neutralization tests with lime were carried out on the water sample from Robule Lake. The results of sequential neutralization testing showed that concentration of Fe ions could be lowered below the maximal allowable concentration prescribed by Serbian legislation at pH value 4. The other metal ions: Cu, Zn, and Ni needed pH value 7, and Mn and Cd needed pH 10 for effective removal.
