Physico-mathematical model of uranium concentrate extraction processing in countercurrent columns cascade

Autor: Noskov, M. D., Istomin, A. D., Korotkevich, V. M., Kozyrev, A. S., Shikerun, T. G., Shamin, V. I., Mikhailova, N. A., Romanov, M. E.

Publikováno v: Bulletin of the Tomsk Polytechnic University

Mathematical model of extraction recycling uranium concentrate in cascade of countercurrent column cascade has been presented. The model describes nonequilibrium interconnected physical-chemical processes subject to a large number of components (uran
