  • 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

  • Beneficial Reuse of Coal Ash from Dominion Energy Coal Ash

    Nov 30, 2017· Fly ash historically comprised approximately 75% of the coal ash generated annually in the US. Because modern coal-fired power plants produce a number of other products besides ash, fly ash currently only represents about 40% of the total CCPs generated in the US (other CCPs include non-ash products such as FGD materials, defined below).
