Plasma and plasma-frequency method of usefulness components extracting from ore minerals and concentrates: extracting of fluorine as carbon fluorides from fluorite

摘要

Extraction of fluorine in the form of carbonfluorides has been realized by the process of fluorite charge andcarbon treatment with electrical arc, direct induction heating atvarious frequencies and combine processing with high-frequencyarc and direct induction heating. Super-equilibrium yield of carbonfluorides and calcium carbide have been attained at high-frequencyprocessing the charge.
