ACID MINE DRAINAGE TREATMENT AND METAL REMOVAL …

Acid mine, drainage (AMD) is a dangerous form of pollution characterized by high acidity (pH near 2-3) and substantial quantities of sulfate and soluble metals (Fe, Zn, Cu, Ni, Pb, and Cd ions). The accumulation of sulfate in sediments and aquatic systems causes the release of toxic sulfides that can damage the environment ( Utgikar et al., 2002 ; Ghigliazza et al., 2000 ).
