EXPORTech Company, Inc., and the Bradley Pulverizer Company report the results of preliminary testing of a new method of coal desulfurization employing dry magnetic separation. High ash and high sulfur minerals are extracted from the internal circulation of an air-swept mill used to prepare pulverized coal for combustion. This reject is cleaned using ETCi`s ParaTrap dry magnetic separator. Clean coal recovered from the mill reject is returned to the mill feed. Significant levels of pre-combustion coal desulfurization have been achieved at high Btu recovery for Lower Kittanning coal by combining coal pulverization and dry magnetic separation.
