Efficiency of ball milled South African bentonite clay for remediation of acid mine drainage

Author: Masindi, Vhahangwele ; Gitari, MW ; Tutu, H ; De Beer, Morris Date: Dec 2015 The feasibility of using vibratory ball milled South African bentonite clay for neutralization and attenuation of inorganic contaminants from acidic and metalliferous mine effluents has been evaluated. Treatment of acid mine drainage (AMD) ... 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
Integrated acid mine drainage management using fly ash

Author: Vadapalli, VRK ; Gitari, MW ; Petrik, LF ; Etchebers, O ; Ellendt, A Date: Jan 2012 Fly Ash (FA) from a power station in South Africa was investigated to neutralise and remove contaminants from Acid Mine Drainage (AMD). After this primary treatment the insoluble FA residue namely solid residue (SR) was investigated as a ... Read more
Integrated removal of inorganic contaminants from acid mine drainage using BOF slag, lime, soda ash and reverse osmosis (RO): Implication for the production of drinking water

Author: Masindi, Vhahangwele ; Osman, Muhammad S Date: Jun 2017 This study evaluated the interaction of acid mine drainage (AMD) with Basic Oxygen (BOF) slag. The reaction proved that pH = 10, and 99% metals removal and 75% removal were achieved. Sulphate concentration was reduced from 18000 to 4000 mg/L ... Read more
Neutralization and attenuation of metal species in acid mine drainage and mine leachates using magnesite: a batch experimental approach

Author: Masindi, Vhahangwele ; Gitari, WM ; Tutu, H ; De Beer, Morris ; Nekhwevha, N Date: Aug 2014 This paper evaluates the potential application of amorphous magnesite for remediation of Acid Mine Drainage (AMD). Magnesite was mixed with simulated AMD at specific S/L ratios and agitated in an orbital shaker and its capacity to remove ... Read more
Neutralization of acid-mine water with calcium-carbonate

Author: Maree, JP ; Du Plessis, P Date: 1994 Traditionally, Lime is used for the neutralization of acidic effluents. Calcium carbonate should be considered as an alternative because of considerations such as lower cost, low solubility at pH values greater than 7 and simple dosing system ... Read more
A novel technology for neutralizing acidity and attenuating toxic chemical species from acid mine drainage using cryptocrystalline magnesite tailings

Author: Masindi, Vhahangwele Date: Apr 2016 The present study was developed with the aim of beneficiating two waste materials by converting them into a resource. Magnesite tailings, which is the by-product of magnesite mining, was used to remediate acid mine drainage (AMD) which is the ... Read more
Synthesis of cryptocrystalline magnesite–bentonite clay composite and its application for neutralization and attenuation of inorganic contaminants in acidic and metalliferous mine drainage

Author: Masindi, Vhahangwele ; Gitari, MW ; Tutu, H ; De Beer, Morris Date: Dec 2015 The primary aim of this study was to synthesize cryptocrystalline magnesite–bentonite clay composite by mechanochemical activation and evaluate its usability as low cost adsorbent for neutralization and attenuation of inorganic contaminants ...
