Abstract

See full text

A froth flotation method is provided for removing carbon from fly ash which utilizes an environmental friendly conditioning agent. The conditioning agent preferably comprises a biodegradable oil which is added to a slurry containing raw fly ash and water. The conditioning agent renders the carbon in the fly ash hydrophobic such that upon aeration of the slurry, air bubbles attach to the carbon particles and carry them to the surface of the slurry in the form of a froth, such that the carbon may be removed.
