Acid Mine Drainage (AMD) is an environmental problem that eventually occurs in
sulfide rich mine sites. In Turkey most of the metal mines are associated with
sulphide minerals and are potential AMD generators. The purpose of this PhD thesis
is to practice universally accepted tools for the prediction of AMD potential for a new
metallic mine development.
This study involves evaluation of geological data, geochemistry, mineralogy, and
acid-base accounting (static tests) data, obtained from the Erzincan-iliç / Ç / ö / pler Gold
Prospect case.
The mineralization in Ç / ö / pler is in sulfide and oxide types. The oxide is a supergene
alteration and porphyry-copper type gold mineralization is classified as an
intermediate sulfidation. The major lithologies observed in the study area are the
regionally un-correlated meta-sedimentary lithologies, Munzur Limestone, and the
Ç / ö / pler Granitoid.Thirty-eight representative samples were tested for AMD prediction purposes.
Sixteen more were included to the sampling scheme for site characterization.
Both acid producing and neutralizing lithologies are present in the mine site.
Similarly it was revealed that the sulphate sulfur content of the samples were
insignificant that any determined total sulfur amount can be directly considered as
the factor for AMD production.
Geochemical data revealed arsenic enrichments up to 10000 ppm in the study area.
Therefore, during the operational stage, in addition to the planning to avoid or
minimize AMD, it is necessary to take precautions against arsenic mobilization
during the design of the AMD neutralization scheme.
Both Kinetic studies and the heavy metal mobilization related to AMD are kept out of
the scope of this investigation. Similarly, management and abatement stages of
AMD are excluded.
