AB Acid mine drainage (AMD), resulting from mining activities, poses a significant environmentalconcern. It adversely affects metallic materials, particularly carbon steel composites used inmining machinery and structures. Highly acidic and oxidizing compounds like sulfuric acid and ferricions cause corrosion, iron oxide formation, and hydrogen gas release, which degrade carbon steel.AMD also alters the solvent’s properties, dissolving heavy metals and contaminants, and intensifyingthe environmental impact of mining. A 30-week experiment immersed metal plates in AMD to studyits effects. Weekly observations of the plates and solvent were made. The plate measurements andphysicochemical data were analyzed using graphical–statistical analysis and fuzzy logic techniquesto assess the data quality and identify errors. The results reveal consistent findings with prior studies,such as material degradation with weight loss and alterations in acid drainage media, includingincreased pH and total dissolved solids (TDS). These changes in the solvent characteristics stem fromthe dissolution of metal ions from corroded surfaces, reacting with the acid solution. Overall, thisstudy discusses the effects of AMD (acid mine drainage) on metallic materials and emphasizes thesignificance of monitoring and reducing the environmental consequences of mining activities.
