The result of surfactants on froth flotation of unburned
2017-2-15 The efficiency of the flotation of the fine unburned carbon from coal fly ash (CFA) is closely dependent on the dispersion of the collector on the carbon surface. In this work, we carried out the froth flotation tests of CFA using four different surfactants: Sodium Dodecyl Sulfate (SDS), Sodium Dodecyl Benzene Sulfonate (SDBS), Tween-80 (TW

Use of froth flotation to remove unburned carbon from fly
2010-10-26 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. In this paper, the use of froth flotation to remove the unburned carbon from fly ash is described. Three different fly ashes were studied that had loss-on-ignition (LOI

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% [1]. Carbon content in fly ash is within the range of 0.1–25% [2], [3]. Fly ash is mainly used as a raw material for adsorbents, ceramics, glasses, geo-polymers

Characterization of Unburnt Carbon Recovered from Fly
2012-11-27 Characterization of Unburnt Carbon Recovered from Fly Ash by Froth Flotation Total Surface Area Surface area of samples was measured by BET method. The weight of the sample taken was 0.522 gram. The BET surface area was measured with a volumetric apparatus (Micrometrics model) by absorbing and desorbing nitrogen on previously dried samples.

froth flotation carbon from flyash
The froth flotation process to separate unburned carbon from fly ash has been developed by Michigan Technological University. A target of less than 1% carbon in clean ash with 90% or more recovery, or 80% of LOI in the carbon concentrate with 70% or more recovery of total carbon, can be achieved with this process.
