A B S T R A C T PROCESS FOR DEWATERING AQUEOUS COAL SLURRIES A process for the preparation of a dry coal product from two aqueous slurries of coal particles, a first slurry containing relatively small particles and a second slurry containing relati- vely large particles, which process comprises agglomerating the coal particles in the first slurry with 10-30 %w, based on the weight of said small particles, of a binder, mixing the agglomer- ates thus obtained with the second slurry and dewatering the mix- ture with a mechanical means, e.g. a centrifuge, in which the agglomerates at least partly, disintegrate.
