Hydro-geochemical characterizations of a platinum group element groundwater system in Africa

The prevailing hydro-geochemical processes were assessed at an open cast platinum mine. Major conclusions relate to the Acid Mine Drainage buffering within fractured aquifer system associated with the platinum deposit. The oxidation of pyrrhotite from in situ sources is the major contributing factor towards AMD formation. Neutralization of acid in the groundwater system has solved the pH problem but introduced a salinity problem.
