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

Abstract

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 (uranium, nitric acid, iron, silicon, molybdenum, calcium etc.). On the basis of numerical implementation of mathematical model the software was developed and program-technical complex for increasing the efficiency and optimization of operating the extractive columns cascade and achieving the required technological parameters of the output solutions under changing characteristics of the initial solution was developed
