This paper presents the results of the research aimed at the creation of the ilmenite-fluorite welding flux using mineral raw materials of the Far Eastern region. The authors have performed thermodynamic calculation based analysis of the possible physical and chemical processes in the slag system. The experimental research we have conducted resulted in the mathematical dependencies that allow selecting flux components that would ensure the desired properties of the hard facing surfaces formed. Experimental overlay welding sessions were performed to determine the welding-technological characteristics and properties of the welded deposit. The results of the research show that the flux, consisting of 50 % of the mineral components extracted in the Far Eastern region and of 50 % of the standard flux АN22 is basic (В = 1.46) and has a low oxygenation capacity (А = 0.22). This facilitates reduction processes in the slag bath and, as a consequence of, results in obtaining high quality weld deposit. High level mechanical and performance properties of the coatings formed is maintained due to the reduction of alloying elements and possible formation of carbides (CrFe)7C3 or (CrFe)23C6, alloyed cementite (CrFe)7C3 and other substances. As an example, overlay welding under AN22PK-DMS flux produces the maximum content of chrome in the welded deposit of 12 – 15 %, and the maximum content of manganese of 6 %.

The article considers the possibility of expanding the range of fermented milk products enriched with natural sources of biologically active substances, which is an urgent task today, as it corresponds to the concept of state policy of the Russian Federation in the field of healthy nutrition. As a solution to this problem, it has proposed to enrich the curd mass as part of the daily diet. Promising plant raw materials of the Far Eastern region, such as Ahnfeltia tobuchinensis, a representative of the genus of red algae growing in the Far Eastern Seas, are used as functional and enriching ingredients; Dahurian larch wood extract – arabinogalactan (Lavitol-arabinogalactan) and peppermint (Méntha piperíta). Grounded ahnfeltia was used in the size of not more than 0,5 mm. On the basis of the analysis of the composition and properties of the applied non-traditional additives, the possibility of enrichment of curd products with dietary fiber and organic iodine from plant components has been substantiated. Optimal ratios of enriching prescription components to the weight of cottage cheese in a finished product are the following: ahnfeltia powder – 1,5%, arabinogalactan – 2,5%, peppermint – 1%. Also, when determining the optimal dosages of the introduced components, it is proposed to replace the prescription amount of sugar with flower honey, which is a natural sweetener and a powerful antioxidant. Organoleptic and physicochemical parameters of the finished samples have been analyzed. As a result of the research the functional curd product one portion (100 g) of which is capable to satisfy daily physiological need of an organism for iodine for 29,32%, in dietary fibers for 12,38% has been developed.

Analysis of current status and use of lead and zinc resources in the Far Eastern region, on the territory of Primorsky region for many decades and such analysis is of practical importance for evaluation and selection of areas in this field of activity. Russia safeguarded stocks and lead and zinc resources in the long term. On the territory of the Far East region there are significant deposits of these metals, but for single resources most of them substantially less large deposits in other regions of Russia - Siberia, Altai, Ural. Significantly to support lead-zinc industry in the region is possible in case of exploration of new deposits of ores with high quality. Lead and zinc minerals industrial scale in the region undoubtedly has and can be represented by a leading geological-industrial types of fields, but there is currently little studied. You must not reforming the present state of the industry and its innovative development: need to develop intra-regional use of raw materials in the form of the final product, that will give the region's resources development of new incentives. Nonferrous metals resource potential of the region, with an effective strategy to use them can be a significant factor in changing the geopolitical significance of the far eastern part of Russia.

The antiradical properties of hydrolysates and hydrothermal extracts of bivalve mollusks (Anadara broughtonii) from the Far Eastern Region of Russia and their influence on lipid oxidation in mayonnaise were investigated. The radical binding activity of hydrolysates and extracts of A. broughtonii varies from 55% to 89%. The maximum radical-binding activity was observed for acid hydrolysates. The antiradical efficiency of acid hydrolysates is 35%–41% of the BHT (butylhydroxytoluene) index. The antiradical activity depends on the (method of) technological and biotechnological processing of raw materials. Acid and enzymatic hydrolysates and hydrothermal extracts of A. broughtonii in mayonnaise slow down the process of oxidation of lipids and hydrolysis of triglycerides. Acid hydrolysates reduce the speed of oxidation and hydrolysis of lipids in mayonnaise more efficiently than the enzymatic hydrolysates.

The analysis of macroeconomic indicators of the results of solid mineral extraction (TPI) in 11 subjects of the Far Eastern Federal district (DFO) was performed. The total value of production of all types of minerals (DPI) in terms of money at DFO is about 2.4 trillion rubles (45% of total gross regional product (GRP) of the region is equal to 5 trillion rubles.). More than 63% of the volume of DPI is achieved at the expense of fuel and energy resources of the Sakhalin region and the Republic of Sakha (Yakutia). In the dynamics of the region, there is a significant increase in GRP, production and value added for the DPI in general, and the production of fuel and energy minerals, but slower growth in the production of solid minerals. Ore (metal) raw materials of the region’s subjects in its total GRP is about 21%, in value terms-500 billion rubles. The region produces 16-18 types of ore mineral raw materials, including 12 types of raw materials as the main components of production, 4-5 types-as associated components. The main one is gold production (in 2019 more than 170 tons), silver (more than 930 tons). In the Far Eastern Federal district, reserves and resources of the main TPI for the long term have been identified. It is possible to significantly support the mining industry of the region in the case of exploration of new deposits with high-quality ores. Ore mineral raw materials of the leading geological and industrial types are currently insufficiently studied. It is necessary to develop intra-regional use and processing of raw materials to final products, create metallurgical industries, this will give new incentives to the development of the region’s resources. The analysis is of practical importance for evaluating and selecting directions in the deposits of subsurface use.

Article is devoted to a question of financial and economic stability of the enterprises. Uncertainty and instability of the external environment can lead to a slowdown in economic growth, to a decline in production and reduction of investment. In recent years, problems of financial instability and bankruptcy have grown into a category of economic security of the country. Annually for these reasons, thousands of businesses cease operations, which has a negative impact on the social and economic situation of the regions. The article examines the theoretical and methodological tools of financial stability of economic entities as an indicator of the effectiveness of the financial management system in commercial organizations. This is ensured by permanent solvency by maintaining a sufficient level of liquidity of assets (finished goods, receivables, short-term financial investments, etc.). The author made attempts to create a methodology for assessing the financial and economic sustainability of mining companies in the Far Eastern region that are engaged in the extraction and processing of non-ferrous metal ores in order to avoid their bankruptcy and as an exit - merger into a vertically integrated company. This will allow to connect the technological cycle at individual enterprises: from the extraction of raw materials and its processing to the production of high-value products and to increase their competitiveness both on the Russian market and on the world market.
