"PROCESS FOR THE SELECTIVE AGGLOMERATION OF SUB-BITUMINOUS COAL FINES" ABSTRACT OF THE DISCLOSURE The process involves adding a low quality oil to an aqueous slurry of sub-bituminous coal particles to act as a selective agglomerating agent. When the mixture is agitated, as by pumping it through a pipeline loop, the coal particles agglomerate and may later be separated from the minerals by screening. The low quality oil used is selected from the group consisting of bitumen, heavy oil, and emulsions thereof. In a preferred aspect, a light hydrocarbon diluent, selected from the group consisting of kerosene, naphtha, and diesel oil, is added to improve the agglomeration results.
