Abstract

Silica separation and isolation methods providing energy conservation, a decrease in losses and waste of plant raw materials, and the environmental safety of the processes are studied. Using the oxidative ashing and alkaline extraction methods, biogenic silica (SiO₂) samples with a target component content of 76.4–99.9% are prepared. The qualitative elemental composition and structural characteristics of the resulting materials are determined by physicochemical methods.
