The influence of the mineralogical composition of alkaline syenite enrichment wastes on the structure and properties of ceramic tiles has been established. The ceramics obtained after firing at a temperature of 950 - 1100 ° C has an uneven-grained structure, consisting of a fine-grained base (grain size less than 5 microns) and inclusions with a size of 10 - 50 microns (in ceramics with slurry) and up to 120 microns (in ceramics with magnetic fraction). The glass phase is enriched with oxides of aluminum, magnesium and iron, which are part of the syenite enrichment waste, and has a heterogeneous chemical composition. It is shown that the higher content of ferrous minerals in the magnetic fraction in comparison with the sludge significantly intensifies the processes of glass formation and sintering of ceramics, causing low water absorption and high strength.
