MODELS OF ORE-MAGMATIC SYSTEMS OF TUNGSTEN-ORE NODES AND FIELDS
On the geodynamic basis, using morphostructural and geophysical analyzes of the geological environment, the structure of the ore-magmatic systems of the nodes and fields containing the industrial tungsten deposits of a polymetal-tungsten formation is considered. The developed taxon models are designed to identify potentially promising areas in the ore areas containing hidden mineralization.
Keywords: tungsten, formation, geodynamics, geophysics, models ore nodes, fields.

ABOUT A PROBABLE SOURCE OF ALLUVIAL SCATTERINGS OF GOLD STREAM KURANAKH AND STREAM SNOW (VERKHOYANSK DISTRICT, YAKUTIA)
Sources of modern placers can be both indigenous ore accumulations of gold and intermediate reservoirs. Determination of the source of gold placers is of great practical and scientific importance for the prediction of gold-bearing objects. The possibility of localization of a probable source of gold placers opens including the analysis of the morphology and granulometry of gold. This article presents the results of the analysis of gold from alluvial deposits, as well as man-made formations located in the valleys of the streams Snezhnyj and Kuranah (Republic of Sakha).
Keywords: gold, placer deposits, granulometric analysis, source of placers.

DEPOSITS OF THE RESIDUAL TYPE OF THE REPUBLIC OF BASHKORTOSTAN – BASIS FOR THE CREATION OF RAW MATERIAL BASE OF «NON-DRILLING» BARIT
Barite deposits of the residual type of the Republic of Bashkortostan are considered as a promising source for the production of extremely scarce high-quality products. The results of the enrichment of ores of deposits of this type are given, which prove the possibility of obtaining from the latter barite concentrate of class A («non-drilling» barite) and allowing a positive assessment of the prospects for creating a resource base in the region. Activation of work on the search for and involvement in the production of residual deposits will reduce the problem of providing consumers with high-quality raw materials and reduce existing imports.
Keywords: barite, ore occurrence, residual, enrichment, high-quality, raw materials.

TO THE ISSUE OF CHOOSING THE OPTIMAL ALTITUDE OF AN AIRCRAFT FLIGHT DURING OF AIRBORNE GAMMA-SPECTROMETRIC SURVEY
A model of attenuation of gamma-radiation above the earth’s surface has been constructed by analyzing the literature sources and by using the actual material. The altitude of the AGSM survey at a low relief is substantiated at 70-90 meters. Increase of the survey altitude up to 120 meters is possible in conditions of mountain relief, and also in case of integration of AGSM with other geophysical methods. The technical instruction of airborne gamma-spectrometric survey, was approved in 1977, is obsolete, so there is an urgent need for the development of modern instructional documentation and the adoption of relevant special terminology.
Keywords: optimal flight altitude, AGSM, line spacing, scale of survey, gamma-ray intensity, anomaly, geological feature.

THE OPERATIONAL RESERVES OF UNDERGROUND WATER IN IMPAIRED WATER HYDROGEOLOGICAL CONDITIONS OF THE URAL OROGEN
The current practice of assessing the provision of estimated operational groundwater reserves (EOGR) of the vast majority of small and medium (up to several thousand m3/day) deposits (water intake areas) within the Ural Hydrogeological Folded Region (UHFR) is based on quantitative indicators of underground runoff and attracting surface waters of transit rivers (streams) in the designed low-flow periods. This approach does not take into account the close relationship between the underground and surface runoff in the open hydrogeological structures, which underestimates the resource potential of the estimating and exploring deposits (sites) and often functioning water intakes by 1,5–2,5 or more times. The article analyzes the quantitative assessment of the river runoff’s participation in the creation of EOGR of water supply facilities at all stages of the geological process of capturing groundwater and specific recommendations are given to refine the assessment of the provision of estimated EOGR, which will significantly increase the effectiveness of these works.
Keywords: Ural hydrogeological folded region, operational reserves of groundwater, reduction of river runoff, weathering crust, coefficient of water yield.

SELECTION OF THE METHOD OF COMPLEX PROCESSING OF THE IRON ORE OF SEROV DEPOSIT
The influence of the mineral composition and textural-structural features of iron ores from the Serov deposit on the technological properties and behavior of the ore in the beneficiation operations is shown. The revealed dependence was put into the development of a complex scheme for the processing of iron ore. When direct metallurgical processing of the original ore obtained marketable products.
Keywords: technological sample, iron ores, mineralogy, benefication, metallurgy, cast iron, ferrochrome, steel.

NEW APPROACHES IN THE METHOD OF COUNTING MULTI-COMPONENT ORE RESERVES (ON THE EXAMPLE OF THE TOMTOR ORE FIELD)
A new approach to calculating the reserves of complex rare-earth ores of the Northern and Southern sections of the Tomtor ore field, carried out according to the results of the assessment work carried out by the Yakutskgeology in 2015-2016, is presented. New scientific and methodological components have been developed for estimating reserves of rare-earth ores in the North and South sections of four on-board content based on the conversion of useful components into conditional niobium (Nb2O5) while regulating various geological and industrial parameters of the original ore. The results of an optional calculation of the reserves of rare-earth ores in the Northern and Southern sections of the Tomtor ore field are obtained. The corresponding technical and economic calculations for the feasibility study of temporary exploration standards have been carried out.
Keywords: reserves, rare earth metals, Tomtor ore field, feasibility study.

ELEMENTS MOBILITY DEGREE EVALUATION IN TECHNOGENIC SOILS OF THE TAILING DUMP OF TOKURSKAYA GOLD RECOVERY FACTORY BASED ON THE MODEL EXPERIMENTS
Based on a complex analysis of the material composition of the technogenic soils of the tailing dump of Tokurskaya gold recovery factory and experimental data, their potential environmental impact is predictively estimated. Within the combining extraction method the forms of loosely-bonded elements including water-soluble, exchangeable, complex and specifically sorbed compounds have been selected. In order of elements’ transition potentiality to a contiguous media based on loosely-bonded elements profile Ca, As, Mn, Co, and Hg are leading.
Keywords: tailing dump, technogenic pollution, migration, combining extraction.
