Abstract
Systems and methods for beneficiating a recovered fly ash material and/or recovering fly ash from an impound site are described. The method may include thermally treating a first portion of a recovered fly ash material to form a thermally treated fly ash having a first temperature of at least 1000° F., and contacting the thermally treated fly ash with a second portion of the recovered fly ash material to cool the thermally treated fly ash to a second temperature of less than or equal to 500° F. and form a fly ash product. The fly ash product may have a carbon content less than 8% by weight, based on the total dry weight of the fly ash product.
