One of the main pollution sources is industrial effluents such as acid mine drainage (AMD) and other mining effluents. These effluents usually contain high levels of acidity, heavy metals and sulphate. A popular method to treat these effluents before they are released into the environment is lime neutralisation. Although this method is very effective to raise the pH of the effluent as well as to precipitate the heavy metals, it can only partially remove the sulphate. Further treatment is required to reduce the sulphate level further to render the water suitable for discharge into the environment.enAlkali - Barium - CalciumABCABC Desalination processAcid Mine DrainageAMDAMD treatmentBarium carbonatesBarium sulphatePrecipitationSulphate removalReportSwanepoel, H.
