ABSTRACT:
A process and apparatus for dewatering water-containing mineral particles, e.g., pulverized coal and in particular, high moisture content, low rank coal, is described. In one embodiment, the process and apparatus make use of a hydrophobic dewatering aid to displace water chemically and/or interstitially bound to coal particles followed by stripping of the coal particles with a water-miscible solvent to facilitate drainage of such water from the coal particles.
