     · As magnetic separation is the best approach for removal of iron from fly ash, selective raagnetic coating followed by wet magnetic separation has been attempted. Also, most of the plants have wet systems of ash disposal into the settling pond, so wet magnetic separation will be an advantage as the s:turry can be directly fed into the feed tank.As mullite and quartz crystallize during the solidification of fly ash particles, they purify themselves of trace elements by freezing them out into interstitial glass phases. An analytic scheme for routine chemical specification and pollution hazard assessment of fly ash is suggested.
