Geochemical and mineralogical evaluation of toxic contaminants mobility in weathered coal fly ash : as a case study, Tutuka dumpsite, South Africa

The current study therefore aims to provide a comprehensive characterisation of weathered dry disposed ash cores, to reveal mobility patterns of chemical species as a function of depth and age of ash, with a view to assessing the potential environmental impacts. Fifty-nine samples were taken from 3...
