Acid mine drainage (AMD) causes severe environmental pollution because of its high heavy metal content and strong acidity (Gokcekus et al. 2003). Heavy metals (HM), including Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn, have the potential to become a major contamination source and are extremely detrimental to the aquatic and soil environment in general ( Kim et al. 2009 ; Anju & Banerjee 2010 ).
