  • 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.
