Removal of sulphates from South African mine water using coal fly ash
(University of the Western Cape, 2009)
This study evaluated SO4 2- removal from circumneutral mine water (CMW) collected from Middleburg coal mine using coal FA collected from Hendrina power station. The following parameters were investigated: the effect of the ...
Active neutralisation and amelioration of acid mine drainage with fly ash
(University of the Western Cape, 2009)
Fly ash and AMD samples were characterised by standard analytical methods for selection of the test materials. Active treatment by means of mixing fly ash with AMD in beakers and a large tank at pre-determined ratios have ...
The application of high capacity ion exchange absorbent material, synthesized from fly ash and acid mine drainage, for the removal of heavy and trace metals from secondary co-disposed process waters
(University of the Western Cape, 2005)
The objective of this study was to investigate the feasibility of the application of low cost high capacity inorganic ion exchange material, synthesized form collected fly ash and acid mine drainage solid residues, for the ...
Removal of sulphates from South African mine water using coal fly ash
(University of the Western Cape, 2009)
South African power stations generate large amounts of highly alkaline fly ash (FA). This waste product has a serious impact on the environment. Acid mine drainage (AMD) is another environmental problem associated with ...
