Tsvetnye Metally
The articles with different directions, elucidated industrial experience and scientific developments of enterprises, companies, research institutes are presented in the issue.
Collective of authors from Research Institute of Comprehensive Exploitation of Mineral Resources (Russian Academy of Sciences) presents the paper about new methods of platinum group metal concentration from impregnation copper-nickel ores.
Results of conditions researching of heap bacterial leaching of complex copper ore from Udokanskoe deposit, taking into account climatic conditions are presented in the paper by L. N. Krylova, E. V. Adamov, T. A. Pivovarova, T. F. Kondrateva.
About 1.2-2 tonnes and more of red mud are formed during production every tonne of alumina. Hundreds millions tonnes of red mud are collected in the world. In the paper by collective of authors (V. A. Romenets, V. S. Valavin, Yu. V. Pokhvistnev, J. S.Saluja, P. R. Tripathi) the possibility of red mud utilization by Romelt process of liquid-phase reduction with iron extraction and pig iron obtaining is shown.
In the paper by G. S. Makarov it has been reported about metallurgical features of melting and out-of-furnace treatment of molten Al-Mg-Si alloys, the account which reduces metal and energy irrecoverable consumption, and effectively prepares a melt in terms of nonmetallic inclusions, hydrogen and nucleation contents for the operation of continuous billets casting. It empowers to furnish current state of demands to metal quality for extruded section producers.
In the paper by N. A. Belov, A. V. Sannikov, S. S. Mishurov, V. D. Belov the negative influence of silicon on hot-tearing tendency of aluminium alloys as AN2ZhMts (Russian grade) has been experimentally determined. The paper, when the solution of realization of multi-functional multi-operated device for electric actuator control for system of control in chemical and metallurgical industries has been presented by authors, is published in “Automation” section. The device allows to control induction, synchronous andDC motors,(up to 3 simultaneously) and also provides unstressed reversing and dynamic braking, implementation of digital local control loops of various process variables and different kinds of protections and locking systems, possibility of software upgrade, communication with the upper level through USB, RS-485 and Ethernet interfaces. Scientific innovation of the proposed approach lies in elaboration of the universal power part and software for different electric motors control taking into account their special features in the computer-aided control systems.
Staff and editorial board of “Tsvetnye Metally” congratulate on hero of an anniversary, such as Kozyrev V. S., Popov V. A.
The paper about Saint Petersburg Electrotechnical University “LETI” is published in the “Chronicle” section.
