Abstract Acid mine drainage (AMD) and minesite salinity are arguably the most serious threats posed to the environment by open cut mining and mineral processing. AMD arises when sulphur, usually in the form iron sulphide (pyrite) contained in the ore and/or waste materials, is exposed to oxidation, the products of which are leached out as acid. As the pH of the system drops, bacteria begin to catalyse the chemical reaction. Open cut mining and mineral processing also lead to the storage of water on the surface where evaporation raises the salinity of the water. This paper reviews some of the acid mine studies done in recent years, suggests engineered solutions to mitigate the problem and shares some local experiences of AMD and minesite salinity.
