This study investigates the effectiveness of various static methods for estimating element mobility and the acid-generating and acid-neutralizing potentials in mining waste characterized by geological diversity. The objective was to assess the reliability of standard versus simplified leaching and acid-base accounting methods in predicting acid mine drainage (AMD) potential. Various leaching tests, including methods specified by the EPA, were evaluated in parallel with acid-base accounting techniques. Results indicate that simplified leaching tests provide comparable outcomes to standard methods. Moreover, findings suggest that the EPA Method 1311, commonly utilized for waste characterization, is inadequate for accurately representing mining waste properties. The verification of a robust connection between the weathering processes of minerals, acid-base accounting, and leachate chemistry adds valuable insights for improved waste management strategies in mining operations. Overall, this research contributes to the understanding of geochemical behaviors in mining contexts, promoting the adoption of more efficient and effective testing methods for regulatory compliance and environmental protection.
