coal and pyrite run of mine coal were separated by a gravi-tational technique into fractions designated as 1.3 float clean coal and 2.0 sink (pyrite and ash). Dielectric properties were measured and used to predict heating rates. Predicted val-ues suggested that pyrite and ash would heat 1.3–3.3 times faster than clean coal.
