The process of AMD is usually accelerated when mining exposes metal sulphide in mineralized rock and ,mine waste, to oxygen and ,water,, thus causing rapid oxidation of the sulfides. Sulfide oxidation has the potential to produce sulfate, which may turn into sulfuric acid when it is dissolved by rain, leading to the production of acidity drainage.
