Heavy metal pollution and acid mine drainage is a very important environmental concern where waste materials containing metal-rich sulfides from mining activity have been stored or abandoned [ 38 ]. Tailings and rock dumps are associated with the surface impacts which greatly affect surface and ground water quality.
