Column leaching of fine coal tailings: impact on environment and thickener operation

Moyakhe, Dumisane; Fosso-Kankeu, Elvis; Campbell, Quentin (EARET, 2018)

The coal mining sector is synonymous with generating large quantities of waste. A comprehensive fraction of the waste is classified as fines (-500 µm) and ultrafine (-100 µm) particles, which accounts eleven per cent ...
Effect of fine coal tailing porosity on the mobility and speciation of heavy metals in the leachates

Fosso-Kankeu, Elvis; Olivier, Charl; Moyakhe, Dumisane; Barlow, Brad; Campbell, Quentin; Waanders, Frans (EARET, 2018)

The effect of porosity of coal tailings on the mobilization and speciation of heavy metals is important for the implementation of management strategies. In this study, column leaching experiments were carried out to ...
