us4128474a - process forcleaningand dewatering finecoal

A wet mechanical process is described for cleaning, upgrading and dewatering fine coal. The process provides for forming an aqueous feed slurry of fine coal and its associated contaminant particles wherein all particles have a particle portion size of less than about 6 mm. ranging to zero. The feed slurry is separated into coal slurry and refuse slurry portions in a spiral gravity concentrator
