description: This work is devoted to the study of the influence of various parameters and components of the solution on the crystallization of pure copper and mixed sul-phate. The research set the following goals: 1. Search for literary sources on the theory of crystallization; 2. Review of the available data on the system under consideration; 3. Planning an experiment with the most accurate simulation of the industrial process in the laboratory; 4. Analysis of the obtained experimental results and their processing. In addi-tion to studying the behaviour of impurities, the task was 5. Calculation of the main material flows of components in the area of evaporation-crystallization of copper and mixed vitriol. The work was carried out on the basis of JSC "Institute Gipronickel", where a significant part of the actual material was collected: the results of X-ray phase and chemical analysis. Calculations were carried out, showing clearly under what con-ditions copper sulphate with a minimum amount of impurities and mixed sulphate of variable composition are formed. As a result, the influence of various conditions on the crystallization of sulphates and the behaviour of the components was analysed.
