Abstract: The objective of this research was to improve the magnetic separation of coal and pyrite by enhancing the magnetic susceptibility of pyrite in runofmine coal through the use of selective dielectric heating. Separation of pyrite from coal would be facilitated by changing a portion of each pyrite particle to a more magnetic form. Studies included the measurement of the dielectric ...
