Abstract :
As surface oxide ores are depleted, mining operations in the Central African Copperbelt increasingly exploit
deeper sulfide deposits. The storage of these sulfide materials under atmospheric conditions raises the risk of acid mine
drainage (AMD). This study evaluates the acid-generating potential (AGP) of stockpiled ores at Kamoa Copper (Kamoa,
Kakula, Kansoko sites) using a comprehensive methodology including mineralogical characterization (XRD, SEM-EDS),
chemical analyses, static tests (ABA, NAG, paste pH), and kinetic humidity cell tests (ASTM D57446-18).
