Abstract: Processing and use of coal sludge and fine coal enrichment waste (precipitation of filter presses, filter cakes) is currently one of the most important problems in the operation of coal processing plants (CPP), the solution of which will not only reduce fuel losses with waste, but also improve the process of coal preparation, increase the output of concentrate and reduce its cost, significantly improve the environment. The most effective method of enrichment of fine classes of coals is oil granulation methods, which have been actively developed in Russia and abroad over the past decades. Studies of the process of enrichment of finely ground coal by the method of oil granulation using the products of capture of chemical volatile substances of coke chemical production as a collecting agent have been carried out. When working out the methodology of the experiment on coal enrichment by oil granulation method, it is supposed to use medium coal oil of "B" and "B1" types as an oil agent. Due to the relatively low cost of these products, in the future they should be considered as a promising binder. The obtained results of the enrichment of various coals showed high selectivity of the oil granulation process when using coal oil as a binder. It was found that at a binder consumption of 5.0% of the initial coal, a coal oil concentrate with an ash content of 12.6-12.9% was obtained with an initial ash content of 22.0-21.2%.
