The monograph reflects the results of fundamental and applied research in the field of the use of mining waste and mineral processing The monograph reflects the results of fundamental (carried out in accordance with the Plan of Institute of Comprehensive Exploitation of Mineral Resources Russian Academy of Sciences). Ecologically oriented technologies are justified as a recreation of the real logic of human interaction with the environment. A classification of mining waste is given, and environmental safety requirements for wastes as potential secondary raw materials are developed. The methodological foundations of the analysis of technological solutions based on the mineralogical features of mining waste are generalized. Ecological technologies for processing gold-containing waste from mining enterprises are described. Ecological and technological features of the processing of tailings of processing plants containing thin sludge are considered, the issues of the recycling of secondary products for the treatment of industrial waters of mining enterprises, the relevance and methods of sulfuric acid leaching of copper smelting slag are shown, as well as the problems of large-scale recovery of marble and drill cuttings waste in the production of building materials are discussed. Intended for specialists of mining, processing and metallurgical profiles, researchers, teachers and students of higher educational institutions. The authors of the monograph: V.A. Chanturia, I.V.
