OLD TAILINGS REHABILITATION WITH REGARD TO ENVIRONMENTAL IMPACTS AT THE MOOTEH GOLD MINE, IRAN
Abstract
The major impact of early mining resulted from the establishment of this mine tailings, which neutralized hundreds hectares of land, which due poor management and neglect have been subjected to varying degrees of water and wind erosion. Environmental impacts range from water pollution (acid mine drainage derived from oxidation of sulphides, mainly pyrite, and the heavy metals in the Mooteh mine tailings), air pollution in the form of airborne dust from unrehabilitated, partially rehabilitated and reprocessed mine tailings, and the sterilization of appreciable tracts of land where mine tailings are located. The main objective of rehabilitation method or combination of rehabilitation methods at the Mooteh gold mine are for it to have little or no maintenance in long-term and eliminate multiple sources of pollution. Of these, vegetation cover is the most important and requires a variety of preparatory steps including leaching, liming and chemical amelioration.
