Studies on carbon flotation from fly ash - ScienceDirect

2015-11-1  1. Introduction. It has been estimated that 750 million tons of coal fly ash is generated on a global basis annually, and the global fly ash utilization figure is estimated to be 25% .Carbon content in fly ash is within the range of 0.1–25% , .Fly ash is mainly used as a raw material for adsorbents, ceramics, glasses, geo-polymers, concretes, etc.

2021-9-17  The unburned carbon in fly ash inhibits the performance of concrete. A device using the flotation method to remove unburned carbon in fly ash was developed, and the operating condition of the device was experimentally examined. According to the results, the device was able to remove unburnt carbon from fly ash by using the installed micro bubble nozzles and a whirl-type pump.

Froth floatation process for separating carbon from coal ...

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.

ABSTRACT Flotation was proved to be effective for decarburization and removal of dioxins from hospital solid waste (HSW) incinerator fly ash, but weathering makes it difficult. The effects of three types of surfactants including nonionic (Tween 80), anionic (SDS), and cationic (CTAB) at different pulp pH values on the flotation performance of weathered HSW incinerator fly ash were investigated.
