A.S. Zavertkin, V.I. Tjaganova, A.G.Tupolev. Application of chemicals and technological materials in pretreatment of shungite rock // Problems in the rational use of natural and technogenic raw materials from the Barents region in construction and technical material technology. Proceedings of Second International Conference. Petrozavodsk: Karelian Research Centre, 2005. Pp. 71-73
The authors made a study of benefication of high-carbon shungite rock by treating it with alkali, mineral acids, with alkaline waste that is left from cleaning of ceramic moulds for precision steel casting.
The report demonstrates the influence of chemicals and temperature of autoclaving on increase of carbon content up to 97.5% in shungite concentrate.
