The phosphate ore of the Polpinsky deposit contains up to 30 & # 37; silica. In the process of direct acidic processing of phosphorite into mineral fertilizers, silica is a ballast, which is advisable to be removed from the composition of the product. The possibility of using silica as a raw material for the glass industry was substantiated, for which its phase and chemical compositions were established and compared with the current technical conditions.
