Abstract

In the United States, approximately 50 million tonnes of fly ash are generated by electrical utilities annually. The current consumption rate for fly ash materials is less than 20% because most fly ash materials do not meet market specifications and the quality of the ash is inconsistent. A beneficiation process that produces quality-controlled fly ash components has been developed. The synthesis of mullite as a refractory material is one industrial application for the silicate sphere component from the beneficiated fly ash. As-received (untreated) fly ash did not produce a usable mullite refractory. This article discusses the fly ash beneficiation process and mullite synthesis. © 1994 TMS.
