Electrostatic beneficiation of fly ash - ScienceDirect

2017-1-1  Fly ash particles are very fine compared to other minerals that are separated by electrostatics. Measured by dry ultrasonic sieving, fly ash from pulverized coal-fired boilers typically has only 10%–30% of the mass > 325 mesh (+ 45 μm).The median particle diameter is typically 15–20 μm.The median size of the unburned carbon particles is generally larger than the mineral particles.

Recovery, processing, and usage of wet-stored fly ash ...

2017-1-1  The fly ash is combined with relatively low levels of water (typically 10%–20% by mass) which reduces dusting. Examples of use in this form include fill or grout; the material may also be stored in stockpiles. Many power plants in the United States have or will be converted to dry handling and ash conditioning systems. Slurried fly ash.
