A joint project was initiated in 1989 between the University of Kentucky Center for Applied Energy Research (CAER) and the Powell Mountain Coal Company (PMCC) to evaluate the applicability of column flotation for recovery of fine coal from classifying cyclone refuse at PMCC`s Mayflower Preparation Plant. Laboratory and extensive pilot plant studies were conducted on each of the seams processed by the plant evaluating various column operating parameters. These results were used to design a larger 8-ft. diameter x 22-ft. tall column capable of recovering fine coal from the dilute classifying cyclone overflow with a feed capacity of 1,000 gpm. In order to effectively treat the entire plant classifying cyclone overflow stream, a total of four columns operating in parallel were installed in December 1989. This paper outlines four years of operating experience and results obtained with this fine coal recovery circuit.
