Date Dec. 14, 1995A method and apparatus for separation of carbonaceous particles from fly ash utilizes an electrostatic separator having a number of separation zones arranged to define a downward serpentine pathway for particulate material. The separation zones include spaced parallel planar electrodes with collectors positioned at the outlet of each separation zone to direct the respective carbonaceous and non-carbonaceous particles to respective storage hoppers. The feedstock is introduced to the apparatus via a rotary valve at a temperature of about 100 DEG C. and the potential difference between respective pairs of electrodes is about 30 KV.
