A dry separation process for removing pyrite from fine coal utilizing centrifugal and electrostatic methods removed 35 to 55 percent of the total pyritic sulfur (amounting to 70 to 100 percent of available pyritic sulfur) in rejects of 10 to 15 percent. Both separation methods are benefited by restricting the particle-size range and by keeping the pyrite particles as large as possible. Removal efficiency is increased, therefore, by integrating the separation and grinding operations, as in stage grinding.
