The paper presents the results of a study of the tailings of the kaolin “Kyshtym kaolin”, after enrichment of the feedstock in order to obtain quartz sand for the glass industry. Based on the results of laboratory enrichment work, quartz concentrates were obtained corresponding to grades no lower than OOBC-015 (GOST 22551-2019) from which glass was melted using a vacuum compression method and multicomponent glass of the composition SiO₂, Al₂O₃, Fe2O₃, TiO₂, CaO, MgO, Na₂O, K₂O, SO₃.
