ABSTRACT:
A method of using fluorinated hydrocarbons as a carrier to convey mined coal to a separation station. The carrier acts as a parting liquid for beneficiating the coal. The carrier is recovered and returned to the mine for conveying more coal. Some of the returned carrier may be used at the mining face as a dust suppressant. Ash from burning the coal may be returned with the carrier where it is disposed of as waste material.
