The possibility of using rocks form the Khatsavitskoe, Solokhaul’skoe, and Tugupskoe deposits in Krasnodar Krai in the production of basaltic fibers has been investigated. Using laboratory single-spinneret setup it is shown that continuous, thickened, and rough fibers are formed from melts of these rocks in a wide temperature interval. Using a setup with an induction method of melting the raw materials and acoustic blowing of the melt with compressed air, commercial prototype batches of superthin staple fibers, whose main technical characteristics fall into the range regulated by GOST 4640–93, were obtained.
