Critical and Strategic Minerals in the Russian Federation

Global development and scientific and technological progress are intensifying the use of mineral raw materials (MRMs)-the necessary basis for the production of high-tech products. The advanced producing countries of these products are in dire need of various raw materials, which are critical and, as a rule, are supplied from third countries. Strategic is a mineral raw material, which is of particular importance for ensuring the economic development of the country, its defense and security. Due to the complex structure of extraction, processing and consumption of raw materials, many of its types are in short supply. In the world literature, the concept of "deficient MRMs" in its content most closely corresponds to "critical MRMs," that is, raw materials that are critically needed for industry and are characterized by a significant risk of their supplies. Most critical raw materials are needed for production promising high-tech industrial products and new materials and, in particular, for "green technologies" in connection with the course of decarbonization of the economy actively pursued by world powers. In the production of such products, the consumption of MRMs is growing rapidly, especially rare-earth elements (REEs), V, Li and platinum-group elements (PGEs). From the list of 61 kinds of MRMs that are strategic for Russia, the extraction of oil, gas, Cu, Au, PGEs, Ni, apatite ores, K salts, and diamonds (as well as nonlisted coals, Fe ores, Na salts, V, B ores, magnesite, and chrysotile asbestos) fully covers their current domestic consumption in the Russian Federation and the achieved level of export. U, Mn, and Cr ores; Zr; high-purity quartz raw materials (SiO2); bauxite (Al); graphite; fluorite and nonstrategic barite; kaolin; and bentonite are deficient; their exploitation only partially provides domestic consumption, which is largely dependent on imports; it is carried out in insufficient volumes in the presence of significant reserves of relatively low quality. The most deficient in this list are Ti, Li, Ta, Nb, and REEs (usually, there are groups of heavy and light rare earths (HREEs and LREEs, respectively)): their domestic consumption is provided mainly by imports with very limited production (despite large reserves, including low-quality ores). Re, Be, Nb, Ta, HREEs, Y, Sc, LREEs, Ge, Ga, Li, Hf, and Co, and, of nonstrategic MRMs, Bi and Sr, should be considered critical MRMs in the Russian Federation. The most important source of dispersed/associated elements is represented by raw materials of mining enterprises of nonferrous metallurgy: Cu and Zn subsectors, In, Ge, Ga, Cd, Tl, Se, Te, Sb, Bi, etc.; Al subsectors, Ga; for Au and Au-Ag deposits, Sb, As, Te, Se, Bi, Tl. An associated source of lithium is represented by brines of gas-condensate fields. The issues of assessing complex raw materials for high-tech industry are considered using the example of pyrite, porphyry, and gold-ore deposits of the Uralian fold belt, which play an important role in its overall metallogenic potential.
