“…Many researchers have proposed several technologies categorized into active and passive treatment techniques (Bai et al, 2021;Vasquez et al, 2022). Examples of passive techniques are bioremediation, constructed wetlands, phytoremediation (Wibowo et al, 2023a;Wibowo et al, 2022b) and bioreactors (Ka-ot and Joshi, 2022;Thomas et al, 2022;Wang et al, 2021a), while the active techniques include neutralization, precipitation, adsorption, electrochemical treatment, and membrane technology (Angai et al, 2022;Bao et al, 2022;Lee et al, 2022b). Both techniques have advantages and disadvantages (Ighalo et al, 2022) .…”

Acid mine drainage (AMD) is a significant threat to the environment due to its high acidity and metal ion content. To effectively eliminate pollutants from AMD, various approaches are necessary. This review aims to provide a comprehensive understanding of recent advances in AMD mitigation. While treatment technologies have developed to eliminate AMD, they often produce sludge as a by-product and require expensive maintenance. As a cost-effective alternative, the recovery of AMD resources can reduce toxicity and promote reuse of heavy metals and rare earth elements. This review also analyzes the challenges and prospects of AMD mitigation implementation, including current mitigation conditions and knowledge gaps. Researchers can benefit from this review by gaining insight into research progress in this area, identifying strengths and weaknesses of current AMD mitigation applications, and exploring future research directions.

“…Various methods have been developed to remove heavy metal elements from AMD, such as constructed wetland method 13,14 , microbial method 15,16 , neutralization precipitation method 17 , and adsorption method [18][19][20] . Among these methods, the adsorption method is an effective method for the removal of heavy metal ions because of its advantages, which are easy operation, mild adsorption conditions, good adaptability and high efficiency.…”

A new idea to alleviate environmental pollution is the development of low-cost adsorbents using natural minerals and fishery wastes to treat high concentrations of heavy metal pollutants in acid mine drainage (AMD). Adsorbent morphology, adsorptive and regenerative capacity, and application potential are limiting factors for their large-scale use. Oyster shells capable of releasing alkalinity were loaded on the surface of lignite to develop two composite adsorbents with different morphologies (powdery and globular) for the treatment of AMD containing Pb(II) and Cd(II). The results show that the ability of the adsorbent to treat AMD is closely related to its morphologies. The pseudo-second-order kinetic model and the Langmuir model are suitable to describe the adsorption process of OS-M(P), and the maximum adsorption saturation capacities of Pb(II) and Cd(II) are 332.6219 mg/g and 318.9854 mg/g, respectively. The pseudo-second-order kinetic model and the Freundlich model are suitable to describe the adsorption process of OS-M(G). A synergistic result of electrostatic adsorption, neutralization precipitation, ion exchange and complex reaction is achieved in the removal of Pb(II) and Cd(II) by two morphologies of adsorbents. The regeneration times (5 times) and recovery rate (75.75%) of OS-M(G) are higher than those of OS-M(P) (3 times) and recovery rate (20%). The ability of OS-M(G) to treat actual AMD wastewater is still better than that of OS-M(P). OS-M(G) can be used as a promising environmentally friendly adsorbent for the long-term remediation of AMD. This study provides a comprehensive picture of resource management and reuse opportunities for natural mineral and fishery wastes.
