A comparative analysis of the physical and technical properties of existing and proposed perlite thermal insulation products, agricultural components, acoustic fillings, demonstrating a significant improvement in the quality of the latter. In this regard, a selective method for the development of perlite deposits with thin extraction layers is proposed to obtain a homogeneous perlite rock in terms of average density, followed by classification by the size of fractions, which will make it possible to obtain a homogeneous raw material and expanded perlite with a stable set of properties.
