Abstract

Language:

The energy consumption for zinc hydrometallurgy is high in the process of electrowinning. The operating parameters, which include the current density, the zinc iron concentration, and sulphuric acid concentration, influence energy consumption and the cost of electrical power. In order to reduce this cost in the zinc electrowinning process, an optimization method based on a finite element model and kriging model is proposed in this paper. The finite element model calculates the current efficiency and cell voltage, while the kriging surrogate model is used to construct the relationship among current density efficiency, cell voltage, and the operating parameters, thus replacing the time-consuming finite element analysis in the optimization process. The genetic algorithm is employed to find the global optimal solution effectively. Simulation results demonstrate the reliability of the proposed method.
