Tsvetnye Metally

The 8-th issue of the journal «Tsvetnye Metally» (Non-ferrous metals) (August, 2014) shares the problems of theory and practice of concentration, production and processing of non-ferrous metals, complex use of crude ore, economics and management of production and metallurgical processes automation.

The article, published in the section «Economics and management of production», describes the research of the problem of competitive lagging of Russian metallurgy from enterprises of South-East Asian countries (especially China). There were made the conclusions, approving the meaning of innovation policy of metallurgical enterprises as the basic condition of overcoming of competitive lagging from the developing countries.

The article «Development of technology of Udokan deposit ores processing», published in the section «Benefication», describes the carried out laboratory researches in the time of development of Udokan deposit ores processing flowsheet. As a result, the main parameters of technological process were defined. Developed technological scheme provides obtaining of qualitative marketable products with high indices of extraction from sulfide, mixed and oxidized Udokan deposit ores, which, in turn, allows to carry out the processing of all technological types of ores by one flowsheet, and refuse the organization of selective extraction, which is too complex on deposit.

The article by N. V. Vorobev-Desyatovskiy and D. V. Ermakov tells about non-oxidation methods of detoxication of cyanide solutions and pulps of gold-mining industry. These methods are based on ion binding in insoluble or relatively low-toxic strength compounds. Method of cyanide solutions detoxication, using ion-exchange resins (anionites), is also considered in this article together with latest achievements in the area of use of cyanide ions oxidation by atmospheric oxygen on activated coals, functioning as catalysts.

Heat-resistant titanium alloys are widely applied as the materials of components of aviation gas-turbine engines compressor rotor. All these components are exposed to the influence of cyclical loads and high temperatures in exploitation process. The article by M. S. Belyaev, M. A. Gorbovets, O. S. Kashapov and I. A. Khodinev (All-Russian Scientific-Research Institute of Aviation Materials) describes the research of dependence of main strength characteristics, including the fatigue cracks growth ratio with temperatures of 20 and 600 ºC from structural state of heat-resistant titanium alloy VT41 (ВТ41). Research was carried out on forging samples. The forging was manufactured by two different schemes: with final deformation with one-phase area temperatures; and with final deformation with two-phase area temperatures.

The 85-th anniversary of «Giprotsvetmet» institute is in September, 2014. The article, devoted to this event, is included in the section «Chronicle». «Giprotsvetmet» is one of the leading institutes in Russia on designing of non-ferrous metallurgy enterprises, and main designer in the area of copper and lead-zinc sub-branches of industry in Russia and abroad. Institute made a significant contribution in creation and development of Russian non-ferrous metallurgy both in Russia and CIS countries.
