Topic: Semi-Passive Biological Treatment of Acid Mine Drainage

Synopsis: One of the legacies of South Africa’s coal- and gold-mining industries, that has come to light in the past two decades or so, is the decant of acid mine drainage (AMD) once mining operations cease. South Africa’s AMD is often characterised by low pH levels and high sulphate concentrations, which presents particular treatment challenges. Mintek is currently developing a semi-passive biological process for AMD treatment in post-mine-closure applications. This presentation describes the development of the process to the point where a demonstration-scale plant has been constructed and commissioned in the coal-producing heartland of the country, at eMalahleni in Mpumalanga.
