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
Passive remediation of acid mine drainage using cryptocrystalline magnesite: a batch experimental and geochemical modelling approach

Author: Masindi, Vhahangwele ; Gitari, MW ; Tutu, H ; De Beer, Morris Date: Oct 2015 Acid mine drainage is generated when mining activities expose sulphidic rock to water and oxygen leading to generation of sulphuric acid effluents rich in Fe, Al, SO (Sup4) and Mn with minor concentrations of Zn, Cu, Mg, Ca, Pb depending on ...

Remediation of acid mine drainage using magnesite and its bentonite clay composite

Author: Masindi, Vhahangwele Date: Dec 2015 Wastewaters originating from mining activities are usually acidic and often contain high concentrations of Fe, Mn, Al and SO 2 in addition to traces of Pb, Co, Ni, Cu, Zn, Mg, Ca and Na. This wastewater impacts surface and subsurface water ... Read more
