Ivan Groznov

   

President's Technology Advisor
Seligdar

Born on October 18, 1945. In 1963, he went to the Moscow Institute of Physics and Technology.

In 1969, he started the postgraduate course of the same university and defended his PhD thesis in 1972.

Since 1969, he began teaching physics and physical disciplines in higher educational institutions. He worked as a researcher at the L. Y. Karpov Research Institute of Physics and Technology (1966-1973), the Russian University of Chemical Technology. D. I. Mendeleeva Assistant, Associate Professor of the Department of Physics (1973-1979), Institute of Chemical Physics of the Russian Academy of Sciences, Senior Researcher, Head of the Laboratory (1977 – 1997), Moscow Institute of Physics and Technology, Dean of the Faculty of Molecular and Biological Physics (1997-2013).

Since 2013, he has been working at PJSC "Seligdar" as a President's technology adviser. During this time, he published an article in an international journal, received three patents for inventions. He proposed, successfully tested and implemented the re-processing of heap leaching ore piles. He has spent the last three years creating a rotary firing kiln for direct heating of resistant sulfide ores. An oxidative heating factory was built using the developed kiln.

The experience of scientific and pedagogical activity has exceeded 50 years. He has about two dozen publications in domestic and foreign periodicals and about ten patents.

Resistant sulfide golden ores direct heating Rotary kiln

For the first time in world practice, a rotary kiln for direct heating of resistant sulfide ores with a controlled temperature distribution was designed, built and put into operation. Kiln allows performing effective heating of resistant sulfide ores in accordance with the specified technological parameters. Gold recovery during cyanidation increased from 20-30% to 90%
This machinery has extremely competitive technical, operational and economic characteristics in comparison with other technologies for extracting gold from resistant and difficult-to-enrich sulfide ores.
