- 1 - Abstract An improved process is described for agglomeration beneficiation of ground coal in which undiluted heavy oil or bitumen is used as the agglomerating vehicle. The ground coal, water and heavy oil or bitumen are mixed at an elevated temperature sufficient to lower the viscosity of the heavy oil or bitumen to a level permitting easy mixing and at an elevated pressure sufficiently high to prevent boiling of the water. This mixing causes agglo- meration of the carbonaceous solids with the heavy oil or bitumen and the agglomerates obtained are separated from the tailings containing aqueous medium and inorganic solids. The separated agglomerates are preferably used with additional heavy oil or bitumen to form a slurry feedstock for a coprocessing unit. This provides a very efficient total process since the coal agglomeration beneficiation uses a portion of the same heavy oil or bitumen feedstock which is used for coprocessing and no additional hydrocarbon diluent is required.
