froth flotation was used to separate unburned carbon from the –100 mesh portions of fly ash samples. Froth flotation is the most common physical separation technology utilized in the mining industry because of its reliability, low maintenance, and economics. The iron oxide component in fly ash can be extracted with the magnetic separation
