This paper presents an analytical review of scientific works devoted to one of the topical studies in cognitive and cultural linguistics, namely, to the concept of "money", which is included in the corpus of basic concepts of European civilization. Concepts as complex mental formations attract special attention of scientists studying the problem of language conceptualization of the person’s environmental world. Language units of different levels are studied in their correlation with the cognitive structure of the concept knowledge. The framework consists of systematization of the majority of existing scientific results of verbal representation, structuring of the concept of "money" in the context of Russian, English, German, and French. A comparative analysis of the ways and means of language representation of the concept "money" in Russian, English, German, and French sets the combination of versatile and specific features that embody the nature of the concept of "money" in these national languages. The obtained scientific findings represent the opportunities of embodiment of general cultural concept of "money" in national linguocultures. The practical value is determined by the fact that the obtained structured scientific data in the specified conceptual field can be used by scientists when developing linguoculturological dictionaries of basic concepts of European culture, as well as in the development of training courses with the dictionaries in question as content database.

Decrease of mined coal quality results in deterioration of main quality characteristics of coal concentrates: ash content, moisture, calorific efficiency and sintering ability. Application of selective reagent modes of coals flotation is an effective method of solving the problem. Elaboration of the reagent modes should be based on a study of mechanism of reagents action on the coal surface. Study of the aromatic esters effect on the physicochemical and flotation properties of gas coals from the Komsomolets mine of the Kuznetsk coal basin accomplished. It was shown that the low natural floatability of gas coals is due to the significant energy unsaturation of their surface, in particular, the presence of large pores, oxygen-containing groups and mineral impurities. The results of quantum chemical calculations demonstrate that the electrophilic centres of the coal are formed due to the electron density shift to the oxygen atoms. It was determined that the hydrophobization of the coal surface can be achieved using reagents that have more rigid nucleophilic nature compared to water molecules. The study of the quantum-chemical characteristics of aromatic esters suggests that they can interact with electrophilic areas of the organic mass of coal through a charge-controlled mechanism with the formation of charge transfer complexes. Results of the study of the aromatic esters effect on the physicochemical properties of coals surface and calculation of quantum-chemical characteristics of compositions, simulating the organic coals mass and studied reagents, allow to make a conclusion about possibility to intensify the coals flotation process based on application the quantum-chemical approach at the reagents selection.
