Triboelectrostatic beneficiation of fly ash ScienceDirect

May 01, 2001 1.. IntroductionThe utilization of power-plant-derived fly ash has an impact on the cost of power production from coal. The usage has been hindered by recent shifts to low NO x burners which can increase the carbon content of the ash above the specification for its use in Portland cement. Due to the drastic changes in the carbon content in fly ash, post-combustion beneficiation has been a
