Abstract

Problem statement: Acid mine drainage from waste rocks, tailings and other mine components, is one of the most important environmental concerns at mining sites. To attempt to determine the balance between the acid and neutralization potentials of the material and evaluate the possible acid-forming potential of mine waste, many static prediction tests have been developed to evaluate the acid-forming potentials of samples in recent years. Approach: This study attempts to highlight and summarize their essential issues and collates the mining projects that have used such static tests. Results: The advantages and disadvantages of each technique are compared to formulate and present guidelines for the appropriate selection and application of these tests. According to many studies, although several test methods have been modified in recent years, the ABA, NAG and paste pH methods are the most commonly static tests reported for initially indicating the acid-generating and neutralizing potential of samples. Conclusion/Recommendations: To provide confident acidforming predictions and consequently, the best waste management plans, at least several different techniques needs to be applied together in order to classify the acid generating potential of a sample more reliably.
