    Abstract. A laboratory-size electromagnetic device has been built to separate the high-iron magnetic fraction from coal fly ash. Fly ash, the fine particulate matter produced when pulverized coal is buned, contains an average of 18 wt. percent iron expressed as Fe/sub 2/O/sub 3/ found in a distinctive fraction of finely divided, dense, largely spheroidal particles of high magnetic susceptibility
