Developments of the UralNIIstrom Institute in the field of technologies and equipment for enrichment of vermiculite ores and production of expanded vermiculite

Vermiculite deposits are a heterogeneous array of micaceous minerals of varying degrees of hydration with a significant number of host rocks.The development of technology and equipment for both the enrichment of vermiculite ores and for the swelling of vermiculite and hydrosludes should be carried out taking into account their mineralogical features and the composition of the host rocks. The UralNIIstrom Institute has developed a series of installations for the enrichment of vermiculite ores and the production of expanded vermiculite. The developed installations are successfully operated in the Russian Federation/ and abroad.
