Acid Rock Drainage (ARD) Prediction: Static NAG and Net Acid Production Potential Testing

Preventing Long-Term Environmental Liabilities

Mining operations excavating sulfide-bearing host rocks face severe environmental liabilities if waste rock dumps generate acidic runoff. Early-stage geochemical characterization allows proactive waste rock segregation and tailings dam design.

Static ARD Testing Suite

RVA Labs performs comprehensive Acid-Base Accounting (ABA), including Total Sulphur (LECO), Acid Neutralising Capacity (ANC), and single-addition Net Acid Generation (NAG) tests using hydrogen peroxide oxidation.

Regulatory Reporting

Results classify waste materials into Non-Acid Forming (NAF), Potentially Acid Forming (PAF), or Uncertain (UC), providing defensible documentation for National Environment Management Council (NEMC) compliance and mine closure planning.
