September 15, 2020 marks the 85th anniversary of Sultanbek Myrzakhmetovich Kozhakhmetov, a prominent metallurgist, academician of the National Academy of Sciences of the Republic of Kazakhstan, chief researcher of the Institute of Metallurgy and Ore Beneficiation, Doctor of Technical Sciences, professor, laureate of the USSR State Prize in Science and Technology.
He is well known in Kazakhstan, CIS countries and far abroad for his developments in the field of theory and technology of autogenous processes used for processing sulfide concentrates of heavy non-ferrous metals.
After graduating from the Moscow Institute of Non-Ferrous Metals and Gold in 1958, S.M. Kozhakhmetov at the request of the President of the Academy of Sciences of the Kazakh SSR Academician K.I. Satpayev was sent to the Institute of Metallurgy and Beneficiation, where he rose from a senior laboratory assistant to the director of the institute.
For a long time S.M. Kozhakhmetov successfully combined scientific activity with scientific, organizational and social work, being a member of the presidium, academician-secretary of the Department of Earth Sciences, vice-president of the National Academy of Sciences of the Kazakh SSR. He takes an active part in the work of the National Academy of Engineering (NAE) and the National Academy of Natural Sciences (KazNANS) of the Republic of Kazakhstan, being a full member-academician of these academies.
Sultanbek Myrzakhmetovich is a world famous scientist in the field of theory and development of new technologies for the production of heavy non-ferrous metals and related elements. With his direct participation and under his leadership, a scientific direction is developing – physical and chemical foundations and the development of highly efficient and new autogenous processes in copper metallurgy. High-temperature studies of the thermodynamics, kinetics and mechanism of redox processes in sulfide-oxide systems, the controlled vapor-phase mechanism of oxidation and sublimation of unstable metal sulfides, and liquid-phase interactions of matte-slag melts with the gas phase constitute the main areas of physicochemical research by S.M. Kozhakhmetov, performed under his scientific guidance and with the active participation of his many students.
Fundamentally new autogenous processes developed, tested and implemented at copper smelters under the leadership of S.M. Kozhakhmetova together with scientists from Kazakhstan and Russia.
In 1974, at the Irtysh copper-smelting plant, the KIVCET method of smelting complex copper-zinc raw materials was mastered on an industrial scale. In 1985-1987. a joint team of scientists from MISIS, IMOB and GINTSVETMET under the general scientific supervision of Professor A.V. Vanyukov, at the Balkhash copper smelter, a method of melting copper concentrates in a liquid bath (PV – Vanyukov process) was mastered. At present, this plant, with the launch of industrial units PV-1 and PV-2, has been completely transferred to this technology for processing lean concentrates with the output of copper-rich mattes. The Vanyukov process has been developed on an industrial scale in Russia and the Republic of Uzbekistan at the Norilsk, Sredneuralsk and Almalyk copper smelters.
In 1978, for the development and industrial development for the first time in the world of kivcet technology at the Irtysh copper-smelting plant, as part of a team of scientists and engineers of the USSR and Kazakh SSR S.M. Kozhakhmetov was awarded the USSR State Prize in Science and Technology. In the same year, he successfully defended his doctoral dissertation at the Moscow Institute of Steel and Alloys.
In 2004, for the publication of a work with Israeli scientists S.M. Kozhakhmetov and his graduate student E.B. Kenzhaliev in the United States is awarded the honorary titles of Laureates of the International Society of Minerals, Metals and Materials for Extractive Metallurgy, and in 2005 Sultanbek Myrzakhmetovich for his joint scientific activities with CIS scientists becomes the Laureate of the International Academic Popularity Rating “Golden Fortune” in Kiev.
CM. Kozhakhmetov is the author of over 600 scientific works and inventions, including 10 patents of foreign countries (USA, Canada, Japan, Australia, France, etc.).
His students have defended 17 candidate and 5 doctoral dissertations. He was awarded the Orders of Friendship of Peoples, Ormet, medals and certificates of honor of the Supreme Council of the Kazakh SSR and the Republic of Kazakhstan.
Over the past decade, at the Institute of Metallurgy and Beneficiation under the scientific supervision of Academician S.M. Kozhakhmetov, together with his closest associates, developed and tested new processes for contractile pyrometallurgical selection of refractory gold-bearing raw materials and oxidized nickel ores.
Academician S.M. Kozhakhmetov, being one of the leaders of metallurgical science in Kazakhstan, enjoys great authority and respect from both scientists and manufacturers working in the field of non-ferrous metallurgy.
The staff of the Institute of Metallurgy and Ore Beneficiation heartily congratulates Sultanbek Myrzakhmetovich on his anniversary and wishes him good health, creative activity and prosperity!
