Removal of moisture from ultra-fine clean coal (minus 100 mesh) to below 20% level is difficult using conventional dewatering equipment. This paper describes a couple of dewatering approaches which were found to be effective in providing filter cakes containing less than 20% moisture. These approaches involve addition of metal ion-surfactant, and split size dewatering of coal without addition of any reagent.
