Glauconite-containing overburden is a promising raw material for the synthesis of glasses for various purposes

The results of a study on the use of glauconite-containing overburden rocks of the Novodvorskoye deposit of the Pinsk district of the Brest region to produce glasses for various purposes are presented. The compositions of raw materials in the system «glauconite-containing rock – chalk – iron oxide – soda ash» have been developed, the limiting amount of the raw components and basic oxides in glasses have been optimized. It has been established that the main criterion for obtaining high-quality glasses is a rational combination of refractory and low-melting oxides, which ensures the homogeneity of glasses, working viscosity, the ability to form in various ways, the absence of a tendency to crystallization, black color in the mass, as well as a complex of satisfactory physical and chemical properties. The results of the study confirmed the prospects of using the glauconite-containing overburden for the synthesis of glasses for various purposes, which will contribute to the rational use of natural resources and associated minerals of the Novodvorskoye deposit of the Republic of Belarus, and will improve the environmental situation in the areas adjacent to the deposit.
