Continuous pressure filtration is a modern process for the mechanical dewatering of flotation concentrates of coal and similar coal slurries. This method will give a lower moisture content than classical vacuum filtration, the improvement lying in the range 5% to 15%. Eighteen coal slurries have been examined in this survey. They are representative of a wide spectrum of filtered slurries.
