There are records of acid mine drainage where coal, pyritic Sulphur, copper, zinc, silver and lead among others have been mined. Acid mine drainage is produced by the oxidative dissolution of sulphide minerals in the presence of oxygen and water. Treatment methods currently used in South Africa are reverse osmosis and neutralization method.
