2. Acid Mine Drainage Prevention

Acid Mine Drainage Prevention focuses on techniques to control sulfide mineral oxidation during mining operations. It discusses construction methods such as waste rock pile design and push-dumping, physical barriers like capping with dry and wet covers, blending techniques involving alkaline materials, and passivation methods using organic and inorganic coatings. Each technique is evaluated for its strengths and weaknesses, with summaries provided for their mechanisms and materials. Successful case studies, such as the Rum June mine site and Lac Tio open-pit mine, demonstrate the efficacy of these methods in real-world applications. The chapter highlights the importance of selecting the right materials and understanding the environmental impact of each technique, making it a crucial resource for professionals aiming to mitigate acid mine drainage.
