Description:
The report gives results of a thorough physical, chemical, and magnetic characterization of a Pennsylvania coal from the Upper Freeport seam. The powdered coal was then subjected to high-gradient magnetic separations, as a function of magnetic field and fluid velocity, in both a water slurry and an air dispersion. Ash and pyritic sulfur reductions occurred with increasing magnetic field intensities and decreasing fluid velocities. The best results were obtained in water slurries where approximately 50 percent of the total sulfur and 50 percent of the ash were removed. Air dispersions produced insignificant results.
