This paper presents the results of thermodynamic studies on the effect of temperature on the Gibbs energy of the formation of basic minerals of cement clinker (Ca2SiO4, Ca3SiO5, Ca3Al2O6) with the simultaneous distillation of zinc (Zng) into the gas phase from mineral and man-made raw materials, in particular limestone and tailings from the enrichment of non-ferrous metals at the Balkhash processing plant. The research was carried out using the software package HSC Chemistry 6, developed by the Outokumpu metallurgical company (Finland). During the conducted research it was established that the compounds of zinc oxide have an advantage in the process of formation under the influence of the temperature of the main clinker minerals on the zinc compounds in the sulphide form, for example, the forming temperature of the beginning of the reaction with the formation of Ca2SiO4 has virtually no difference, and when the formation mineral Ca3SiO5 forming temperature of the beginning of the reaction is 19,7% lower. And when The Ca3Al2O6 mineral is formed, the formation temperature at the beginning of the reaction is lower by 17,5%, which is less energy-consuming.
