The scientific results of the optimization of raw materials mixtures for the production of cement clinker with the involvement as a secondary raw material – technogenic waste of the enrichment of non-ferrous metal ores, which by their chemical composition are of interest as an iron-aluminum-silicate raw material component. It has been established that the use of non-ferrous metal ore enrichment waste in the raw material mixture in the form of secondary technogenic raw materials contributes to its utilization, reducing the specific fuel consumption during clinker firing by 5.76%, reducing the firing temperature by 50 ° C and obtaining cement clinker that meets the requirements for chemical and mineralogical compositions according to GOST 31108-2016.
