Description
Summary:This work is important due to the development of control systems by hydrometallurgical processes, specifically, the processes of sorption and biosorption. We consider the kinetics of biosorption of silver from secondary production solutions. The decomposition of the working volume of the aggregate is performed according to the specific features of the processes taking place. The dynamic model, in the form of the usual parametric differential equations, describes the phenomena of starting substances in the circulating solution and filling the sorption structure of biosorbents. The presented model-structure assumes that the procedure of the numerical solution of the set of equations using the Runge-Kutta method has been achieved. The calculation of the nonlinearity of the model is isolated into a separate block providing an approximation of the variables according to the values of the variables at the previous iteration.
