ABSTRACT:
Fine coal particles are recovered from a slurry of finely divided coal by mixing coarsely divided coal and a binder together to cause the binder to adhere to the surfaces of the coarsely divided coal pieces, mixing the slurry with the coal pieces having the binder adhered thereto to cause fine coal particles to adhere to the binder over the surfaces of the coal pieces serving as nuclei and thereby form agglomerates, and separating the agglomerates from the remaining slurry portion to recover the fine coal particles along with the coarsely divided coal and the binder.
