Author: Hobbs, PJ Date: Dec 2015 The water resources downstream of the West Rand Gold Field (a.k.a. the Western Basin) have been the subject of considerable interest and discussion in both the media (e.g. Béga, 2010; 2012a; 2012b; 2013; Groenewald, 2010; Jordan, 2015; Kings, ... Read more
An ecotoxicological screening tool to prioritise acid mine drainage impacted streams for future restoration

Author: Oberholster, Paul J ; Genthe, Bettina ; Hobbs, P ; Cheng, Po-Hsun ; De Klerk, Arno R ; Botha, A-M Date: May 2013 Streams impacted by acid mine drainage (AMD) typically present water exhibiting low pH and high metal concentrations. These factors result in the environmental degradation of watercourses. The objective of this study was to develop and evaluate ... Read more
Effect of the addition of zero valent iron (Fe0) on the batch biological sulphate reduction using grass cellulose as carbon source

Author: Mulopo, J ; Schaefer, Lisa M Date: Sep 2013 Mineral mining generates acidic, saline, metal-rich mine waters, often referred to as acid mine drainage (AMD). Treatment of AMD and recovering saleable products during the treatment process are a necessity since water is, especially in South ... Read more
Fate of inorganic contaminants post treatment of acid mine drainage by cryptocrystalline magnesite: Complimenting experimental results with a geochemical model

Author: Masindi, Vhahangwele ; Gitari, MW ; Tutu, H ; De Beer, Morris Date: Mar 2016 This study assessed the fate of inorganic contaminants post treatment of acid mine drainage by cryptocrystalline magnesite. To accomplish that, neutralization and metal attenuation were evaluated and complemented with simulations using ... Read more
Fate of pollutants post treatment of acid mine drainage with basic oxygen furnace slag: Validation of experimental results with a geochemical model

Author: Masindi, Vhahangwele ; Osman, Muhammad S ; Mbhele, Nkhangweleni R ; Rikhotso, Rirhandzu S Date: 2017 Basic Oxygen Furnace (BOF) slag has been widely used for Acid Mine Drainage (AMD) treatment with its reaction chemistry and contaminants attenuation mechanisms barely reported. This pioneer study was therefore designed with the aim of evaluating ... Read more
Fate, transport and effects of pollutants originating from acid mine drainage in the Olifants River, South Africa

Author: Dabrowski, JM ; Dabrowski, James M ; Hill, Liesl ; Macmillan, P ; Oberholster, Paul J Date: Aug 2014 Concentrations of pollutants were measured in water, sediment and algal samples collected along a longitudinal gradient from a stretch of the Olifants River, South Africa, that receives acid mine drainage (AMD) from the Klipspruit River. The ... Read more
Focus on CSIR research in pollution and waste: Biological sulphate removal technology

Author: Godfrey, Linda K Date: Aug 2007 Acid mine drainage (AMD) is formed when the mineral pyrite comes into contact with oxygen and water, producing elevated sulphate, metal and acidity concentrations. Biological sulphate removal technology can be used to treat AMD, using cost ... Read more
Focus on CSIR research in pollution and waste: High sulphide Concentrations tolerated by sulphate reducing bacteria

Author: Greben, H Date: Aug 2007 Acid mine drainage (AMD) is a common result of mining activities caused by bacterial oxidation of sulphide minerals (pyrite) that results in sulphate rich waste water. AMD can be treated biologically in the presence of sulphate reducing ... Read more
Geophysical delineation of AMD in the Cradle of Humankind

Author: Van Schoor, Michael ; Hobbs, Philip Date: Aug 2016 Acid mine drainage (AMD) and its effect on surface and groundwater resources in the Cradle of Humankind (COH) area near Krugersdorp is a pertinent and well-documented concern. In 2008, a water resources monitoring programme for the area was ... Read more
An in-vitro assessment of the genotoxic impacts of Acid Mine Drainage in the human MCF7 cell line

Author: Botha, S ; Botha, A ; Genthe, Bettina Date: Oct 2012 Chemical compounds and heavy metals can damage the DNA of living cells. If not repaired these DNA aberrations can initiate a cascade of biological consequences at the cellular, organ, whole animal; ultimately affecting the community and ... Read more
An interest group at work: Environmental activism and the case of acid mine drainage on Johannesburg’s West Rand

Author: Funke, Nicola S ; Nienaber, S ; Gioia, C Date: Feb 2012 From an environmental perspective, South Africa faces many challenges that affect both its ecological biodiversity as well as its socio- economic and socio-political security . One of the most prominent challenges is acid mine drainage (AMD) ... Read more
