Separation of unburned carbon from coal fly ash: A review

Jul 15, 2019 A bench-scale parallel triboelectrostatic separator has been used for beneficiation of weathered fly ash particles by Cangialosi et al. . Two different configurations of the electrodes were adopted to determine the mass fractions of positively and negatively charged particles, i.e., charge distribution, in raw fly ash.
