The spherical agglomeration process provides an attractive method for the cleaning and recovery of fine coals in the form of compact oilbonded pellets. In treating a washery effluent containing 50 minus 20 micron material by this technique, the slurry was first mixed under vigorous agitation with oil to deash and dewater the fine coal. The flocculated coal pulp was then formed into larger ...Chat Online
