    The paper presents the industrial results of the fine coal particle fractions (< 2 mm) desulphurization process investigation. The purpose of the research was to evaluate the sharpness of the finest coal particles separation in spiral separators. Performing this task, the representative samples of the feed and separation products were collected in two energetic fine coal beneficiation plants. The granulometric and densimetric analyzes of the samples, as well the chemical analyzes of individual class-fractions were performed. Then, the separation sharpness factors were calculated on the basis of the separation curves approximated by Weibull distribution function. This was the basis for making conclusions concerning the adequacy of selecting separators working and technological system parameters.
