WEBDec 1, 1989 · 1. Introduction In the coaloil agglomeration process for refining coal, oil is added to an agitated coal slurry. The hydrophobic coal particles are wetted with the oil, but not the hydrophilic clay particles and other residues. The coal particles then agglomerate into particles large enough to be separated from the residues by means of a sieve.
