This article describes the classification of methods for treating beneficiation waste in the process of forming tailing dumps. The need for such classifications is caused by the fact that during the many decades of operation of the Kryvyi Rih Mining and processing plant (MPP) in the tailing dumps, which occupy an area of about 10,000 hectares, huge masses of beneficiation waste have accumulated, which can be considered man-made deposits. The development of industry and the need to support its raw material base, the increase in the productivity of mining enterprises cause an increase in the volume of waste output to dumps (tailing dumps). Such a provision leads to the emergence of numerous contradictions, the elimination of which requires the adoption of the necessary technological and ecological balanced solutions. In the article, the main principles of waste management are discussed. The classification of methods for treating mineral beneficiation waste in the process of implementing the principle of an ecologically oriented relationship to natural resources in the process of forming tailing dumps and sludge dumps formation is to divide many multi-parametric objects into a limited number of homogeneous classes or groups, identical in terms of technological, engineering-geological and other properties. The developed classification of methods for treating bene-ficiation waste is built taking into account the hierarchical importance of classification features. Time periods of application and intra-class compatibility of methods for treating beneficiation waste in the process of forming tailing dumps by classes A and B were established on the basis of a patent search, taking into account the time period from the invention to the introduction of the patents into production. The classification of methods for treating beneficiation mineral waste in the process of formation of tailing dumps is presented in the form of a table. The development of a classification of methods for treating benefi-ciation waste in the process of formation of tailing dumps made it possible to identify the drawbacks in the methodological provision of their construction technology and to show the direction of further scientific research.
