Abstract: Concentrating tables are a group of one of the oldest and most precise gravitational concentrators with a broad spectrum of application. They were used mainly for the anthracite enrichment process in the domestic coal industry. Conducted research prove that they can be also used for the enrichment of fine grained coals types. The article discusses the results of coal sludge enrichment using WILFLEY concentration tables, as the results obtained show that coal sludge enrichment using these concentration tables allows for the production of coal concentrates and half-products of satisfying quality parameters, the ash content of which varies between several and a dozen or so percent. The reciprocal connection between the actual contents and enrichment process has been determined based on a dependency analysis between the changing characteristics. The correlation analysis allowed for an evaluation of the dependencies between the technological parameters of the enrichment process and the obtained qualitative-quantitative parameters results, which allows the given mineral enrichment process to perform correctly. The enrichment process of the studied sludge has been performed using the most unfavorable construction parameters i.e. using sulcate plate, its inclination angle remained at 6°, furthermore studied material has not been hyphenated.
