BENEFICIATION OF FLY ASH - ROCKTRON MINERAL

The fly ash being processed contains residual carbon in the form of unburnt coal and char, commonly characterised by measurement by Loss on Ignition (LOI) and typically comprising 8-14% of the fly ash. The residual carbon is a valuable material that can be removed from the suspension by known techniques of froth flotation or pneumatic froth flotation. Froth flotation utilises differences in ...

Coal-derived unburned carbons in fly ash: A review

Beneficiation of fly ash to segregate relatively UC-free or UC-rich splits for beneficial re-use can be done by size classification, electrostatic separation, and froth flotation, as well as density separation, acid digestion, and incipient fluidization. Thermal processing may also be used to burn off the UC, leaving a relatively UC-free fly ash as the product. Keywords: Unburned carbon; Coal ...
