FULL CYCLE PRODUCTION AND TECHNOLOGICAL CHAINS AND PRODUCTION-CONSUMPTION BALANCES OF STRATEGIC MINERAL RAW MATERIALS AS THE BASIS FOR FORMING A CONSOLIDATED ORDER

In the context of the import substitution policy, an urgent task is to increase the demand for domestic strategic mineral raw materials. A mechanism for this may be the organization of a consolidated order. Measures in this direction can be implemented on the basis of the formation of full-cycle production and technological chains and production-consumption balances.

Keywords: strategic mineral raw materials, import substitution, consolidated order, full cycle production and technological chains, demand matrix, material systems analyses, production-consumption balance.

PLACER DEPOSITS AS THE SOURCE OF STRATEGIC MINERAL RAW MATERIALS

Placers have a significant place in the mineral resource base of strategic types of minerals both in Russia and the world as a whole. In the current political and economic conditions, when there is an urgent need in a short time and with a shortage of financial resources to organize the processes of import substitution and self-sufficiency of the country with strategic types of mineral raw materials, it is placers that make it possible to the problem of providing Russia with tin, titanium, rare (including rare earth) metals in a short time and with minimal costs.

Keywords: strategic metals, placer deposits, gold, tin, titanium, rare metals, diamonds.

GEOINFORMATION TECHNOLOGIES IN FORECASTING AND MINERAGENIC RESEARCHES

The work, based on the use of geoinformation technologies, proposes new approaches to the allocation and justification of prospecting areas, taking into account the concept of mineral-forming systems, as well as the use of the latest tools and methods. The results of multifactor GIS modeling in combination with a mineral systems approach to the analysis of the main factors of ore genesis are presented. As a result of a comprehensive analysis oregenetic, a structural weighted forecasting and search model of the south-eastern Transbaikalia was created, reflecting promising areas for conducting forecasting and mineragenic studies on a scale of 1:200000 — 1:50000. The proposed approach makes it possible to optimize decisions aimed at ensuring the sustainable development of the mineral resource base of the Russian Federation.

SPECIFIC FEATURES OF MINERAL COMPOSITION OF HIGH-TITANIUM ILMENITE ORES AFFECTING THEIR ENRICHMENT

The article presents the results of a mineralogical study of high-titanium ilmenite ores as part of prospecting and evaluation in order to assess their quality. The data received testify that ores with a simple mineral composition and favorable textural and structural characteristics have mineralogical features that adversely affect their enrichment by gravitational and magnetic methods. The main ore mineral ilmenite and the rock-forming minerals have a clear contrast in electrical properties, so they may be effectively separated by electrical methods.

Keywords: high-titanium ilmenite ores, enrichment, isomorphic impurity, opening, intergrowths, contrast, specific magnetic susceptibility, conductivity, density, concentrate. intergrown pieces.

ON THE POSSIBILITY OF COMBINED PROCESSING OF KOLA TITANIUM-CALCIUM RAW MATERIALS

On the territory of the Kola Peninsula there are deposits containing elements classified as critical (titanium, niobium, lanthanides, etc.), which are so necessary for the development of modern industries. This paper presents the results of research, which have prospects to be realized in industry in case of combined use, for example, of titanium-calcium raw materials in the form of sphene and perovskite concentrates. The search for conditions of their combined sulfuric acid processing will allow to obtain import-substituting products and reduce the radiation danger of technological processing.

OBJECTIVE POSSIBILITY OF USE OF TECHNOLOGICAL DEVELOPMENTS FOR MINING AND EXTRACTION OF RARE METALS AT IN-GROUND LEACHING WELL OBJECTS

Analysis of exploration data and in-situ leaching results, as well as the instability of the metals market indicates that the extraction of rare metals, which simultaneously pass into solution during the uranium extraction by in-situ leaching, is not always effective when processing the entire volume of pregnant uranium-containing solutions. A scheme for selective advanced extraction of rare metals from uranium solutions using mobile units and targeted sorbents is proposed.

Keywords: production unit, optimization, in-situ leaching, productivity, rhenium, rare metals, selectivity, well, uranium, efficiency.

THE NATURE OF CHANGES IN URANIUM ORES UNDER THE INFLUENCE OF GLYCERINE SOLUTIONS  IN THE PROCESS OF HEAP LEACHING

Each technological process is associated with the peculiarities of the material composition of ores, genetic, textural-structural, physico-mechanical characteristics, the laws of mineralogy and nature. Leaching, as a heterogeneous process involving two phases — a solid and a solution, according to the results of studies of uranium ores, showed the nature of the variability of the technological «life» of minerals in pieces in a pile of heap leaching under the influence of a homogeneous mixture of a leaching slightly acidic solution using glycine — the destruction of minerals and the formation of new mineral forms. The involvement of an amino acid (glycine) in the technological process led to the excitation of organic life — microorganisms (micromycetes), contributing to the disintegration of mineral particles, complexation and sorption of a useful component.

Keywords: metasomatically altered granites, heap leaching, aqueous solutions of glycine, destruction, disintegration, microorganisms, luminescence.
