This paper reviews the fundamentals of the technology and theory of the process of thermal activation of vermiculite-sungulite conglomerates contained in the waste of the Kovdor phlogopite-vermiculite field. An analytical physical model has been developed to describe a single-layer flow of vermiculite-sungulite conglomerate vibro-transported in a thermal field using a vibration hearth platform of an electric furnace. The absorptivity and reflectivity of a dense single-layer array of the processed conglomerate located on a plane under thermal radiation conditions have been determined. Using sungulite, pyroxene, olivine, and a number of other minerals, the correlation of their absorptivity with relative thermal diffusivity and thermal conductivity was demonstrated.
