Case Studies of Neutral and Acid Rock Drainage Analysis

Public perception towards mining is not always positive due to environmental impacts resulting from neutral and acidic rock drainage. Neutral and acid rock drainage can impact water quality leading to additional permitting hurdles, operational challenges, and costly water treatment solutions. Lessons learned from the geochemical characterization of two historic mining sites provide insights to the pitfalls of mine planning and engineering design. Engineering designs can be optimized to mitigate potential geochemical reactions by using a multidisciplinary collaboration to mine planning.
