The possibility of extraction of metals from ores of different genesis, containing low-dimensional structures of rare and noble metals, increases their commodity value and, in a deficit for some types of metals, leads to the need to search and develop new nature-like technologies, which can be used to extract from ores of different genesis almost all valuable noble, rare earth and nonferrous metals regardless of their concentration. This article presents the results of studying the processes of comminution and flotation to extract low-dimensional structures of noble and rare metals from carbonaceous ores using low-temperature and energy impacts at successive stages of the ores' transformation. With the use of modern mineralogical, physical and chemical methods of research of composition, structure and properties of ores, the initial samples, concentrates and tailings after enrichment were studied. During the study, it was established that the difficulty of extraction of strategic metals from carbonaceous hard-enriched ores consists in fine dissemination of valuable components in concentrator minerals, mutual penetration of ore mineralization into each other and into rock-forming minerals, and in proximity of physical, chemical and technological properties of minerals, which complicates selective extraction of valuable components in concentrates. Also, difficulties in enrichment are associated with high flotation activity of waste rock, which significantly reduces the quality of concentrates.
