19.08.2016 · Increasing production and disposal of coal fly ash (CFA) is a matter of serious environment concern. However, CFA contains various beneficial metals and mineral matters whose demand is increasing in the industrialized world, while natural supplies are diminishing. Therefore, recovery of these potential resources from CFA can be an alternative way to save mineral resources, as well as to …
Value in Waste: Fly Ash Reuse and Recovery …
One of the primary targets for recovery from fly ash has been alumina; most fly ash contains between 25 – 30% aluminum oxide (Al 2 O 3)¹. Some sources of fly ash in China have been shown to contain as much as 45% alumina. ² In addition to its use in producing aluminum metal, alumina is used throughout a host of industries as a catalyst, pigment, abrasive, and a long list of other materials.
