<p><span>This paper features economic-geographical, historical and political comparison between Patagonia and Siberia as the biggest resource-oriented peripheries of the world. A conclusion is made about the similarity of the social-economic role of these regions as a low-populated raw material base with small share of industry. Although the regional policy toward Patagonia has never been regulated by any program or strategic document the way it is in Siberia and East regions of China, some success has been achieved, especially in oil refining. The article analyzes the main governmental acts aimed at overcoming the raw material base role and decentralizing the Argentinean economy in the second half of XX century. The general problems obstructing the realization of the long-term measures are the political instability of </span><span>Argentina and its high dependency on the economy on foreign capital. The experience of Patagonia in the field of tax regulating, company registering limits and capital planning can be interpolated to the situation in Siberia and can become the subject of a more detailed research.</span></p>

The purpose of this article is to perform research to improve the stability, quality and efficiency of gasoline-alcohol fuel compositions, as well as obtaining high-octane gasolines corresponding to the modern standards with the addition of alcohols and their mixtures to these gasolines. Research methods: The article considers physicochemical methods for studying the stratification of alcohol-gasoline mixtures, determining the water content in them, as well as determining the octane number of alcohol-gasoline compositions. Results: The raw material base and possibilities of bioethanol production in Ukraine as an ecological additive to gasoline and as a way to increase their octane number were studied. Stratification temperatures of alcohol-gasoline mixtures and octane numbers of A-92 gasoline with different alcohol content were determined. Discussion: It is proposed to use higher concentrations of ethanol (bioethanol) in gasoline mixtures more than 40% of alcohol, because it does not require dehydration. It is proposed to use an additional fuel pump, which would work only for mixing the fuel mixture, to prevent stratification of the fuel-ethanol composition during its long-term storage in the car’s tanks.

<p>The given article contains the research results of carbon-containing chromite pellets’ production from off-grade raw material with application of internal coal-mining overburden rocks as flux. Besides, for the purpose of improvement of ecological situation in industrial regions and expansion of a raw-material base for ferrochrome and pigments manufacture we suppose to use in a charge composition the dust of aspiration units and electrostatic precipitators, which is formed at the preparation of raw materials and production of chromite pellets. The production technology of chromite pellets with use of a slime formed at the concentration of chrome ores as a binding substance was developed. Testing the suggested technology has been carried out in laboratory and trial conditions. The data of a chemical composition of initial components of a charge and calcined carbon-containing chromite pellets have shown economic and ecological efficiency of the developed technological process. Research results lead to the conclusion that the proposed granulation feedstock mixture pellets with a moisture content of 11–12% are obtained crude granules have a compressive strength of 2.3–3.2 kg/splashed. Increasing the content of Cr<sub>2</sub>O<sub>3</sub> in the pellets to 7.6% occurs due to the increase in the extraction of chromium oxide and due to the charge of chromium oxides contained in the sludge, as well as removal of the batch formulation was heat treated carbonates, and volatile organic substances. It was established that during this mode, the temperature in the lower layers is about 1200 °C, and a reduction in natural gas consumption achieves 50% and the residual carbon content in the pellets is about 1.5%, which leads to improvement of technical and economic indices of production chromite pellets and ferrochrome.</p>

Abstract In this article, work was carried out to study the chemical, mineralogical composition and toxicological properties of waste (phosphogypsum, phosphorus slags, overburden) of the phosphorus industry, the optimal content of the grain composition of gravel-sand mixtures in the composition of road mixtures (crushed stone, sand-gravel, sand) and structures of the Zhambyl region of the Republic of Kazakhstan. The possibilities of using slag-mineral mixtures in the year - round construction of highways were studied on the basis of a comprehensive study of the physicochemical processes of hardening and the formation of the structure of slag-mineral materials at negative temperatures. Technological regimes for the construction of roads of various technical categories from slag binding materials, reformed after long-term freezing, have been established. New, unparalleled, binding road mixtures have been created to increase the utilization of waste from the phosphorus industry and expand the raw material base of road building materials. The main directions of application of road mixtures based on industrial waste for the purposes of road construction have been developed: construction of structural layers of road pavements; construction of road bed layers.

The study presents the research results confirming environmental safety of the ceramic material used for construction purposes, produced basing on low-plasticity clay from the Vladimir region with the introduction of 2.5 wt. % boric acid, 5 wt. % of electroplating sludge and 30 wt. % of cullet. The material environmental safety has been previously confirmed by Daphnia mortality method in diurnal water extracts from the chipped ceramic material samples, including possible mechanical damage and deterioration during the operation. The experimental studies embraced the determination of heavy metal ions concentration in diurnal extracts from the chipped ceramic material samples in neutral and acidic media. Additional studies dealing with the heavy metals migration into the extracts were carried out in static mode during 20 days. The research results confirm the environmental safety of ceramic material in neutral and acidic media during the heavy metals immobilization, caused by ceramics self-glazing and vitrification. The research results proved that the production of the developed material will expand the regional raw material base, will contribute to the utilization of large-capacity and toxic waste with simultaneous manufacturing of high-quality and environmentally friendly construction products for new buildings construction or existing buildings and structures reconstruction.

The article discusses the prospects of the Malo-Chipiketsky zone in the southern part of the Patomsky quartz-bearing region of the Baikal province, as a potentially probable new raw material base for granular and transparent quartz in the east of the country. The assessment of the area prospects was carried out according to the algorithm developed by FSUE TsNIIgeolerud for studying quartz objects, which includes a set of the most effective methods for assessing quartz raw materials, quartz concentrates and products from them. The research results showed high efficiency of the algorithm. The studies made it possible at the stage of prospecting to expressly, with a high degree of probability, sort out objects according to the quality of raw materials, identify ore-formation types of quartz and outline possible directions for the use of raw materials. The results were used in the selection and contouring of promising sections of quartz veins to assess the predicted resources of the selected ore-formation types of quartz.
