ABSTRACT
Recovery and economic utilization of fluorine compounds from the phosphate industry are important problems in the chemical industry, economy, medicine, and agriculture. Recovery of fluorine-containing compounds is theoretically and practically possible in all existing technologies in phosphate raw material chemical processing. The amount and quality of fluorine-containing by-products or salable fluorine chemicals indicate the technical level of a fertilizer plant and simultaneously, qualify or define fertilizer technologies according to environmental and sanitary standards.
