The dielectric properties of both raw and beneficiated fractions of a Jharia coal sample were measured in the frequency range 100 kHZ-12 MHZ. It has been observed that as ash yield increases, dielectric constant also increases. An empirical relation A = ae3 + b has been proposed, where A is the ash
