Contamination of soil, water and air by heavy metals, especially lead, poses a detrimental threat to our environment, human health, aquatic and terrestrial animals and plants. Lead uptake, transport, and accumulation by plants and animals as well as the potential for its propagation into the food chain exacerbate its toxic health effects. Lead does not undergo degradation or decompositions. It is estimated to persist in the soil for years. Thus, its long persistence in the environment contributes to its lingering health and toxic effects. Historical lead pollution results from a variety of human activities such as past practices of lead-related industrial processes, smelting, and combustion of coal ; mining activities , use of lead based paints and automotive exhaust fumes , manufacture and use of agricultural fertilizer, insecticides, and pesticides.

The research was conducted based on the results of the writing and defense of 21 qualification papers on the methodology of teaching the French language in institutions of higher education, defended during the last ten years under the scientific guidance of the author of this publication.

This article is dedicated to the researching of French views on the problem of the famine in Ukraine It was established that the professional reports about the Holodomor appeared in France only in the late s. A special place in the French historiography is taken by the research of the famine in Ukraine gathered in the collective monograph «The Black Book of Communism». Most French scientists concluded that it was an artificial famine organized by Stalin and his entourage to curb the bearers of national consciousness and the enemies of collectivization in Ukraine. Keywords: French historiography, the history of the famine , the war with peasants, Ukraine. Рустамжон Эгамберди ев. Vitaliy Guro. Almalyk Mining and Metallurgical Combine is the supplier of molybdenite concentrate in the form of calcined granules. Decreasing of kaolin content leads to decreasing of the pellet durability, while its increasing leads to the difficulty of the access of oxygen in granules. In both cases, sulfur content in marketable product grows. Besides, kaolin in cinder content complicates the sublimate Re2O7, ammonium leaching of molybdenum and gold and silver extraction from its processing cake. This paper searches the pelletization scheme, minimizing this disadv antage. The approach is based on partial or complete replacement of kaolin by organic component of the charge, burning during the granule calcining. Polyacrylonitrile and cellulose glicollic acid production wastes were chosen as an organic component. During the choice of the binding, alternative to kaolin, the authors were guided by its functional applicability as a component of the charge, giving hydrophilic and mechanical prop erties. As a result of the researches, there was defined the necessary range of these indicators for various combinations of mineral-organic binders. There were found the charge compositions, providing the required exploitation and technological properties of marketable product. There were carried out the successful pilot tests of charge mixtures. The advantages of new compositions were defined: the charge impoverishment is decreased, and valuable components are easier extracted from molybdenite concentrate. The change of the charge composition does not lead to the changes of pelletizing technology and processing of granulated product. Key words: molybdenium ore, molybdenite, granulation, organic binder, kaolin, calcining furnace, rhenium. Log in with Facebook Log in with Google. Remember me on this computer. Need an account?
