Understanding Acid Mine Drainage: Prevention and Management in PNG

Acid mine drainage (AMD) represents one of the most significant environmental challenges facing Papua New Guinea's mining industry. The tropical climate, high rainfall, and diverse geology of PNG create unique conditions that require specialised geochemical expertise. This article explores the science behind AMD, the prediction methods used including acid-base accounting and kinetic testing, and the management strategies that Crystal Green recommends for mining operations in Papua New Guinea.
