This paper discusses the use of an innovative reactor constructed from natural waste substrates for the passive treatment of acid mine drainage (AMD), a major environmental concern from mining operations. AMD is characterized by acidic water with high levels of toxic ions and heavy metals, posing significant ecological risks. Analytical techniques such as FTIR, SEM-EDS, XRF, and XRD were used for material characterization, while Ion Chromatography, ICP-OES, and ICP-MS were employed for anion and metal analysis. The reactor achieved high recovery efficiencies for metals (Feł⁺, MnČ⁺, CrČ⁺, CuČ⁺, NiČ⁺, PbČ⁺, Alł⁺, and ZnČ⁺) and SO42- anions. This novel approach offers an effective, low-cost, and energy-efficient solution for AMD treatment, benefiting the mining industry by providing a sustainable method for recycling and reusing valuable resources, such as clean water and metal ions, thus reducing operational costs. |
