Industrial and laboratory tests of the possibility of gravity separation were carried out with the aim of verifying the sharpness of the separation in the process of coal separation, as well as assessing its impact on the technological indicators of the process. Parallel research was carried out on two different samples of raw coal: from the anthracite mine "Vrska Cuka" and the lignite mine "Lubnica". The Ecart probable values are Ep=97.5 kg/m3 and 40 kg/m3, respectively. Such results only confirm the fact that grain size affects the value of Ep, that is, that coarser-grained products are separated better, more efficiently than finer-grained products.enVrska CukaLubnicaGravity SeparationCoalconferenceObject
