In 2001, Korea produced a total of 4.91 million metric tons of fly ash, approximately 63.3% of which was recycled. Almost all of the recycled fly ash are used in concrete mixtures and cement industry. Therefore, in order to develop a new usage to increase the utilization of the fly ash, conductive induction was used in this research rather than triboelectrostatic. By applying conductive induction, we could verify the possibility of obtaining high purity fly ash below 1%LOI and high carbon fly ash over 70%LOI from raw fly ash. In this test, the potential difference between the two electrodes was conducted by changing the range of 8 to 16 kV.
