Predicting whether mine tailings or waste rock dumps will generate acidic drainage requires balancing the Maximum Potential Acidity (MPA) generated by sulphide oxidation against the inherent Neutralization Potential (NP) provided by carbonate and silicate minerals.
RVA Laboratories pairs static Sobek titrations with multi-stage Net Acid Generation (NAG) tests to calculate the Net Neutralization Potential (NNP) and provide definitive ARD risk classifications.
