• Description:
  A dry separation process for removing pyrite from fine coal by use of centrifugal and electrostatic methods removed 30-50 percent of the total pyritic sulfur (equivalent to 50-70 percent of the available pyritic sulfur). Both separation methods were benefited by restricting particle size range and keeping pyrite particles as large as possible. Removal efficiency, therefore, was increased by integrating the separation and grinding steps as in stage grinding. With stage grinding, nearly 90 percent of the available pyritic sulfur was removed from a Pittsburgh seam roof coal. [Description provided by NIOSH]
