Use of froth flotation to remove unburned carbon from fly

21/12/2006  The fly ash from coal combustion often has a high unburned-carbon content. This can make it unusable as a cement admixture, which is the major fly ash utilization market. As a result, high-carbon fly ashes are currently disposed of by landfilling, at sometimes considerable expense. In this paper, the use of froth flotation to remove the ...

Froth floatation process for separating carbon from coal ...

In this process, the carbon of the fly ash is frothed up, and the non-frothed part of the fly ash, which is dominated by mineral materials settls down. Thus, the carbon and the mineral materials which are originally mixed together in the fly ash can be separated. The conventional froth floatation process generally comprises the steps of: adding the fly ash into a mixing tank containing a ...
