    SOCIAL AND POLITICAL INTEGRITY AND POLITICAL AND LEGAL ORDER

    Abstract: The article analyzes the essence and main characteristics of political integrity and political order. It presents various interpretations and research positions related to the justification of the latter. The theoretical and methodological basis of the work is domestic and foreign studies of political scientists, sociologists and lawyers. The paper uses ideological (phenomenological, sociocultural, systemic, etc.), general scientific (analysis, synthesis, analogy, etc.), as well as concrete scientific (historical-political, the method of political modeling) approaches and methods. The authors argue that in the context of the interrelationship of state, legal, political integrity and order, it is necessary to use the conceptof “political and legal order” as more adequate, since the latter allows to comprehensively present and investigate the institutional and normative organization of society, based on political, legal norms, ideas, values and ideals, that ensures the orderliness of relations and reflects the specifics and patterns of development of a particular socio-cultural system.Keywords: power, state, law, politics, order, political process, society, social dynamic

    The article presents the results of experiments intended to beneficiate gold-bearing mineral raw materials by column flotation with the use of micro aeration of pulp through a dispersant system. The influence of the pressure level in the pressure system of dispersants within the range from 202,65 to 1013,25 KPa was studied during the experiments. It was found that the parameter of 607,95 KPa enables to achieve the optimal balance of the precious metal mass yield and the content in the concentrate, with a final gold recovery of 87 %

    Intensification of copper leaching from heaps using biological oxidation

    Get PDF
    The article presents the results of experiments intended to leach copper from ore heaps of complex mineral composition biochemically. The processing of such heaps is complicated due to the presence of oxidized copper minerals among significant fragments of sulfide minerals and iron-calcium silicates. This factor does not allow to perform standard sulfuric acid leaching effectively without the use of additional oxidation catalysts, or to apply beneficiation methods for that kind of raw materials. Use of A. Ferrooxidans bacteria adapted to the composition of the copper dump, as a bio-catalytic agent, significantly accelerates the leaching process and increases the copper recovery degree into the productive solution

    Experimental researches were realized in 54 rats with. modeling of wound defects of lower extremities. Study of effectiveness of combined. local appIication of miliacyl and. light therapy in complex treatment of festering wounds was realized. in 20 patients and. another 20 patients with similar wounds were included in the control group. Clinical, microbiological, morphofunctionaI and experimental-histological researches proved high efficiency of local appIication of miliacyl and. light therapy in the complex treatment of festering wounds

    Reparation of tissues of purulent wounds at the Miliacylum treatment under conditions of infection was studied on 54 white mongrel male rats with simulated wound defects. Clinical and morphofunctional studies proved high efficiency of Miliacylum. in the treatment of purulent wounds

    A study of the biohydrometallurgical method for extracting gold from flotation tailings

    This paper shows the results of the comparative study of efficiency of gold extraction methods from technogenic flotation tails by agitation cyanidation and biooxidation followed by leaching. A representative sample of flotation tails was taken at gold extraction plant of Altyntau Kokshetau LLP. Experimentally, an increase in the efficiency of leaching gold from flotation tails during preliminary bacterial oxidation was found. By biochemical leaching, 72 % was extracted, which is 7 % more than using expensive sodium peroxide and 10 % more than using the traditional method of cyanidation

    Research of biochemical gold recovery method using high-arsenic raw materials

    Get PDF
    This article contains the results of experiments to recover gold from complex mineral raw materials containing more than 15 % arsenic. Laboratory tests showed that standard cyanidation recovers only 26,4 % of gold into the solution. Additional oxidizing reagents used increase the leaching efficiency and enable to recover more than 40 % of gold during subsequent cyanidation. The efficiency has been established for replacement of cyanide with thiourea and thiosulfate solutions. 79,5 %, i.e. the maximum recovery rate, was found in the experiment with preliminary oxidation with T. Ferrooxidans, a bacterial culture, followed by leaching with a thiourea solution
