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 ...
