Abstract: Anthracite is the highest type of coal. Total anthracite reserves account for 1 % of the world's coal reserves. The features of technological schemes of anthracite enrichment at five processing plants are investigated. Given the unique properties of anthracite and its relatively small global reserves, there is a need to maximize the extraction of useful components in the finished product. The existing methods for evaluating the efficiency of separation of coal and anthracite of class 13-100 (150) mm in gravity apparatuses are considered and analyzed. A probabilistic method is proposed for calculating the extraction of fractions of different densities into the concentrate and waste of SKVP heavy-medium separator, which allows evaluating the technological efficiency of enrichment.
