1998-12-1  Froth floatation process for the processing of a fly ash has been known in the art. 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.
