Abstract

A technology for the regeneration of fluorine to produce calcium fluoride from a saturated solution of gas purification had developed. Investigated the optimal conditions for the synthesis of calcium fluoride gas cleaning solutions. Production of calcium fluoride will reduce the cost of secondary cryolite, and the purchase of a primary CaF2 to 80 %. The laboratory study on extraction of fluoride from solid waste leaching process followed by obtaining secondary fluorides. Waste technology will reduce the waste of aluminum production, to receive income from the use of recycled materials and implementation of carbon concentrate in other industries
