Abstract: Analysis of the state of the enrichment technologies used to separate the fine fractions of ores and materials shows that there are problems in obtain-ing conditioned products from such raw materials with the achievement of acceptable recovery, ensuring the effectiveness of the technologies used. Difficulties in the separation of minerals with their low size do not allow efficient processing of numerous stocks of materials from various deposits by the gravity method. The possibilities of many traditional methods of enrichment when using them for the separation of fine fractions have been exhausted. It is necessary to concentrate more the efforts of scientists and production specialists on the practical solution of basic technological op-tions in new scientific fields with the development and introduction of new apparatus designs. Unsolved opportunities remain when using the separation of small and thin classes of mineral mixtures based on the use of centrifugal fields. There is a need to continue the study of the laws of this process and practical solutions to its hardware design. It is necessary to develop the theoretical foundations of the process of separating small particles on round concentration tables by studying the dependence of the efficiency of separating materials on technologically significant factors of the designs of gravity centrifugal devices.
