Abstract
Spheres are released from within plurospheres by mixing a fluid with fly ash or bottom ash particulate material obtained by burning coal to form a slurry. The slurry is vibrated at an ultrasonic frequency and with sufficient power that plurospheres in the particulate material are cracked open to release spheres of the material which are encapsulated within the plurospheres. The so-treated material is separated from the slurry to obtain the released spheres.
