Adsorption and desorption of zinc and copper in acid mine ...

On the other hand, acid mine drainage contains various metal ions, such as zinc, copper, iron, and manganese which are toxic for the ecosystem in a certain concentration. One of the solutions to remove these metal ions is through adsorption. Therefore, the study of adsorption and desorption of zinc and copper onto synthetic zeolite was conducted.

Mine Drainage

Mine drainage can pose serious water-quality problems. In Colorado alone, more than 1300 miles of streams are impacted by metal input associated with mining activity. An understanding of the processes that control metal transport and attenuation in these waters is critical in assessments of the potential environmental impact of mine drainage.
